Background Art
[0002] In recent years, methods of shaping using a water-curable material such as cement or gypsum and an additive manufacturing apparatus have been proposed. For example, Patent Document 1 discloses an "additive manufacturing method capable of stably manufacturing a shaped object having a delicate and diverse design even when the hydration of a cementitious mixture progresses and the fluidity of the mixture decreases."
[0003] On the other hand, techniques for varying the production rate of mortar according to the scale of the construction work to be applied are also known. For example, Patent Document 2 discloses a mortar kneading apparatus that rotationally drives a mortar kneading shaft in a variable speed manner.
[0004] In addition, various efforts have been made regarding the control of equipment during additive manufacturing. For example, Patent Document 3 discloses an additive manufacturing system capable of achieving labor saving in the construction of a laminated structure by using a predetermined learning model. Further, Patent Document 4 discloses a three-dimensional shaping system that uses a detection device for detecting information correlated with the discharge amount of a nozzle and adjusts the rotational speed of a screw so that the discharge amount of the nozzle becomes constant.

[0014] Also, in various information processes according to one embodiment, an input and an output corresponding to the input can be realized. Here, if an output is obtained as a result of the input, the aspect of information (hereinafter referred to as reference information) referred to in such information processing is not limited. The reference information may be, for example, rule-based information such as a database, a lookup table, a predetermined function (including a judgment formula such as a regression formula constructed by a statistical method), a learned model in which the correlation between the input and the output is learned in advance, or a large language model capable of outputting a desired result by inputting a prompt.
[0015] Also, in one embodiment, the "part" may include, for example, hardware resources implemented by a circuit in a broad sense and information processing of software that can be specifically realized by these hardware resources. Also, in one embodiment, various information is handled, and these information are represented, for example, by physical values of signal values representing voltage and current, the level of signal values as a set of binary bits composed of 0 or 1, or quantum superposition (so-called quantum bits), and communication and calculation can be executed on a circuit in a broad sense.
[0016] Furthermore, a circuit in a broad sense is a circuit realized by combining at least a suitable combination of circuits, circuits, processors, and memory. The processor may be a general-purpose processor or a dedicated circuit. In other words, it includes application-specific integrated circuits (ASICs), programmable logic devices (for example, simple programmable logic devices (SPLDs), complex programmable logic devices (CPLDs), and field programmable gate arrays (FPGAs)), etc.
[0017] 1. Overall Structure This section describes the overall configuration of the molding system of this embodiment. Here, the molding system is capable of performing the manufacturing method of the molded object described above. Figure 1 is a diagram showing the overall configuration of the manufacturing system 100. Figure 2 is a diagram showing the overall configuration of the molding system 200.
[0018] The manufacturing system 100 shown in Figure 1 includes an information processing device 1 and a printing material manufacturing device 2. The printing material manufacturing device 2 manufactures 3D printing materials and is configured to communicate with the information processing device 1, enabling the exchange of various types of information. The communication line in this communication includes the internet and wireless networks, mediating data exchange between devices connected to the same line.
[0019] Furthermore, the molding system 200 shown in Figure 2 includes the aforementioned manufacturing system 100 and a 3D printer 3. That is, the molding system 200 shown in Figure 2 includes a 3D printing material manufacturing system 100 and a 3D printer 3 configured to print the 3D printing material manufactured by the manufacturing system 100, and is configured to manufacture a predetermined object. The 3D printer 3 shown in Figure 2 may also be configured to communicate with the information processing device 1.
[0020] The systems exemplified in the manufacturing system 100 and the molding system 200 consist of one or more devices or components. Therefore, the information processing device 1 alone can also be referred to as one of the various systems. The elements that may constitute the manufacturing system 100 and the molding system 200 will be described below.
[0021] [Information Processing Device 1] The information processing device 1 is a device that performs various information processing in a manufacturing system 100, etc. Figure 3 is a diagram showing the hardware configuration of the information processing device 1. The information processing device 1 has a communication unit 11, a storage unit 12, a control unit 13, a display unit 14, and an input unit 15, and these units are electrically connected by a communication bus 10. The following describes each of the units provided in the information processing device 1.
[0022] (Communications Section 11) The communication unit 11 is configured to transmit various electrical signals from the information processing device 1 to external components. The communication unit 11 is also configured to receive various electrical signals from external components to the information processing device 1. Furthermore, the communication unit 11 may have a network communication function, enabling the communication of various information between the information processing device 1 and external devices via a communication line.
[0023] (Storage unit 12) The storage unit 12 stores various types of information as defined above. This can be implemented, for example, as a storage device such as a solid-state drive (SSD) that stores various programs related to the information processing device 1 executed by the control unit 13, or as a memory such as random access memory (RAM) that stores temporarily necessary information (arguments, arrays, etc.) related to program calculations. The storage unit 12 stores various programs and variables related to the information processing device 1 executed by the control unit 13.
[0024] (Control Unit 13) The control unit 13 is, for example, a central processing unit (CPU) not shown. The control unit 13 realizes various functions related to the information processing device 1 by reading predetermined programs stored in the memory unit 12. That is, information processing by software stored in the memory unit 12 is concretely realized by the control unit 13, which is an example of hardware, and can be executed as each functional unit included in the control unit 13. These will be described in detail later. Note that the control unit 13 is not limited to being a single unit, and may be implemented with multiple control units 13 for each function, or a combination thereof.
[0025] (Display section 14) The display unit 14 may be included in the housing of the information processing device 1, or it may be an external component. The display unit 14 displays a graphical user interface (GUI) screen that can be operated by the user. It is preferable to use a display device such as a CRT display, liquid crystal display, organic EL display, and plasma display, depending on the type of information processing device 1.
[0026] (Input section 15) The input unit 15 may be included in the housing of the information processing device 1 or it may be externally attached. For example, the input unit 15 may be integrated with the display unit 14 and implemented as a touch panel. If it is a touch panel, the user can input tap operations, swipe operations, etc. Of course, a switch button, mouse, QWERTY keyboard, etc. may be used instead of a touch panel. In other words, the input unit 15 receives operation input made by the user. This input is transmitted as a command signal to the control unit 13 via the communication bus 10, and the control unit 13 can execute predetermined controls and calculations as needed.
[0027] [Printing material manufacturing equipment 2] The printing material manufacturing apparatus 2 may constitute part of the 3D printing material manufacturing system 100. While the printing material manufacturing apparatus 2 may have various elements, in this embodiment, it will be described as an apparatus equipped with a predetermined mixing tank 21. The mixing tank 21 may include a stirring blade 211 configured to agitate the contents of the mixing tank 21, a motor 212 for rotating the stirring blade 211, and input sections (input sections 213, 214) configured to allow raw materials to be introduced into the mixing tank 21. Here, the input section 213 is configured to allow the introduction of a first raw material that, when mixed with other raw materials (a second raw material), can produce 3D printing material. Specifically, in the printing material manufacturing apparatus 2 shown in Figure 1, etc., the first raw material stored in the storage section 22 is introduced into the mixing tank 21 in accordance with the opening and closing of the valve V2. This first raw material is, for example, a powder, but may be a raw material in various other forms. Furthermore, the input section 214 is configured to allow the introduction of a second raw material that, when mixed, produces 3D printing material. In this embodiment, the second raw material is shown as water W, and the water W is introduced into the mixing tank 21 in accordance with the opening and closing of valve V1.
[0028] The printing material manufacturing apparatus 2 may also include a removal unit 23 configured to remove the contents of the mixing tank 21 (the 3D printing material mixed in the mixing tank 21). This removal operation can be achieved by opening and closing a valve V3. The printing material manufacturing apparatus 2 is also equipped with a pump P1 for sending the manufactured 3D printing material to the outside. As shown in Figure 2, typically the manufactured 3D printing material is sent to the 3D printer 3 and subjected to the printing process.
[0029] The printing material manufacturing apparatus 2 may have a different configuration or additional configurations than those shown in Figures 1 and 2, depending on the raw materials used and the properties of the 3D printing material being manufactured. For example, if powder is used as the raw material, a screw may be used to feed the powder into the mixing tank 21. In addition, the printing material manufacturing apparatus 2 may be equipped with various sensors for managing the temperature and pressure inside the apparatus.
[0030] Here, we will describe the 3D printing material produced by the printing material manufacturing apparatus 2. As mentioned above, the 3D printing material in this embodiment is made by mixing multiple types of raw materials. In the printing material manufacturing apparatus 2 shown in Figure 1, a configuration in which a first raw material (powder) and water W are mixed is shown as multiple types of raw materials, but more specifically, the multiple types of raw materials that can produce 3D printing material may include a hydraulic material and water. That is, such a hydraulic material hardens when water is added (the viscosity of the material changes), but according to the manufacturing system 100 of this embodiment, the configuration regarding the formulation of the raw materials is adjusted, so as a result the properties of the 3D printing material are easily stabilized. In addition to the water W in the configuration in which the first raw material (powder) and water W are mixed as described above, or instead of water W, a liquid admixture may be mixed with the first raw material (powder). In other words, the various raw materials for the 3D printing material in this embodiment may include a hydraulic material and water and / or a liquid admixture.
[0031] Furthermore, the 3D printing material is not limited to the above and may be a variety of materials. In exemplary embodiments, the 3D printing material may be a molding material that is mineralized via hydration, polymerization, or firing. More typically, the 3D printing material may be mortar, concrete, or ceramic material. Furthermore, from the viewpoint of stabilizing the manufacturing process, the 3D printing material may be a combination of materials selected from, for example, a binder (A), fine aggregate (B), admixture (C), fibrous material (D), etc., as shown below (mortar).
[0032] ·Binding material (A) The 3D printing material of this embodiment may include a binder (A). Here, binder (A) is a general term for inorganic materials that contribute to the strength development of mortar and concrete. Such a binder (A) gives a predetermined crystal (mineral) through a hydration reaction (i.e., the binder (A) shown below corresponds to a hydraulic material).
[0033] Here, the binder (A) may contain cement components (A1). These cement components (A1) may include components selected from the group consisting of ordinary Portland cement, moderate-heat Portland cement, low-heat Portland cement, rapid-hardening Portland cement, sulfate-resistant Portland cement, blast furnace cement, and fly ash cement.
[0034] In addition, the binder (A) may contain admixtures (A2). These admixtures (A2) may include components selected from the group consisting of fly ash, blast furnace slag (fine) powder, limestone (fine) powder, stone powder, silica fume, and expansive agents (limestone-based expansive agents). These admixtures (A2) can typically be blended in combination with the cement components (A1) described above, but the binder (A) may also be composed solely of these admixtures (A2).
[0035] These binders (A) may be used individually or in combination of two or more types. When using two or more types in combination, binders with different particle sizes may be mixed.
[0036] • Fine aggregate (B) The 3D printing material of this embodiment may contain fine aggregate (B). In this embodiment, fine aggregate (B) refers to aggregate that passes through a 10 mm mesh sieve completely and passes through a 5 mm mesh sieve by mass of 85% or more (JIS A 0203:2014).
[0037] The type of fine aggregate (B) may be set as appropriate depending on the application. For example, fine aggregate (B) may contain one or more components selected from the group consisting of sand, mountain sand, land sand, sea sand, silica sand, crushed sand, and slag fine aggregate. These fine aggregates (B) may be used individually or in combination of two or more types. When using two or more types in combination, fine aggregates with different particle sizes may be mixed.
[0038] • Admixture that imparts thixotropy (C) The 3D printing material of this embodiment may contain an admixture (C) that imparts thixotropy. This admixture (C) can contribute to improving the thixotropy of concrete or mortar. Note that the admixture (C) here does not correspond to the binder (A) and fine aggregate (B) mentioned above, but refers to any agent that contributes to improving the thixotropy of the resulting concrete or mortar.
[0039] The admixture (C) may be appropriately selected from known materials capable of imparting the aforementioned properties. Although not necessarily limited thereto, the admixture (C) may be an organic compound having a polar group in its chemical structure. The polar group here may be a monovalent group having a heteroatom, such as a hydroxyl group, carboxyl group, hydroxyl group, or amino group, or a divalent bond (linking group) having a heteroatom, such as a urethane bond, amide bond, urea bond, ester bond, carbonyl bond, ether bond, or thioester bond. These polar groups allow the aforementioned organic compound to exert intermolecular interactions, making it easier to impart thixotropy to the molding material. On the other hand, the admixture (C) may be an inorganic compound such as a silicate (layered silicate) or clay. Furthermore, the admixture (C) may be a low molecular weight compound (for example, with a molecular weight of 1000 or less) or a high molecular weight compound (for example, with a molecular weight exceeding 1000). As an example, the admixture (C) that imparts thixotropy may contain one or more components selected from the group consisting of cellulose, modified cellulose, minerals, nanofibers, urethane, xanthan gum, dieutan gum, starch ether, guar gum, polyacrylamide, carrageenan gum, agar, protein, and latex.
[0040] Examples of modified cellulose that can be used as admixture (C) in this embodiment include carboxymethylcellulose, methylcellulose, hydroxypropylmethylcellulose, hydroxyethylcellulose, and hydroxypropylcellulose. Although cellulose and the modified celluloses mentioned above usually exist in a fibrous form, they are treated as admixture (C) in this specification because they have a high effect in imparting thixotropy.
[0041] Examples of minerals that can be used as admixture (C) in this embodiment include clay minerals such as attapulgite, bentonite, montmorillonite, kaolin, and sepiolite.
[0042] Examples of nanofibers that can be used as admixture (C) in this embodiment include carbon nanofibers and cellulose nanofibers. Although these nanofibers usually exist in a fibrous form, they are treated as admixture (C) in this specification because they have a high effect in imparting thixotropy.
[0043] Examples of synthetic fibers that can be used as admixture (C) in this embodiment include polyolefin compounds such as polypropylene and polyethylene, polyvinyl alcohol, and polyvinyl acetate.
[0044] Examples of urethanes that can be used as admixture (C) in this embodiment include various urethane-based thickeners used as urethane-based association type thickeners. Examples of these urethane-based association type thickeners include "Tixostar" manufactured by Nippon Materials Technology Co., Ltd., the "Adekanol" series manufactured by ADEKA Corporation, and the "SN Thickener" series manufactured by Sunopco Corporation.
[0045] Examples of proteins that can be used as admixture (C) in this embodiment include amino acid condensates having a predetermined molecular weight.
[0046] Examples of latex that can be used as admixture (C) in this embodiment include chloroprene rubber latex and acrylic latex.
[0047] • Textile materials (D) Furthermore, the 3D printing material of this embodiment may also contain a fibrous material (D). By appropriately incorporating this fibrous material (D), it is possible to improve the strength of the resulting molded object and to balance the lamination properties and pumpability. Note that the fibrous material (D) in this specification does not correspond to the components listed as thickeners (C).
[0048] The type of fiber material (D) can be set as appropriate. For example, fiber material (D) may include at least one fiber material selected from the group consisting of metal fibers, carbon fibers, aramid fibers, PP (polypropylene) fibers, PVA (polyvinyl acetate) fibers, PE (polyethylene) fibers, glass fibers, nylon fibers, and PBO (polybenzoxazole) fibers.
[0049] In addition, the fiber material (D) may include naturally derived fiber materials. Examples of naturally derived fiber materials include plant-derived fiber materials and animal-derived fiber materials. Here, "plant" in plant-derived fiber materials refers to plants such as bamboo, hemp, rice, and wheat that can be used to produce fiber materials industrially. "Animal" in animal-derived fiber materials typically refers to sheep, etc.
[0050] The fiber length (average fiber length) of the fiber material (D) is preferably 1 to 30 mm, more preferably 3 to 25 mm, and most preferably 5 to 20 mm. The content of the fiber material (D) in the molding material can be appropriately set depending on the application. When the molding material includes a binder (A) and fine aggregate (B), the content of the fiber material (D) may be in the range of 0.5 to 2.5 parts by volume, 0.6 to 2.2 parts by volume, or 0.7 to 1.9 parts by volume, when the total of the binder (A) and fine aggregate (B) is 100 parts by volume. By setting it within such a range, it is possible to balance the curability of the molding material with the improvement of the mechanical properties of the resulting molded object.
[0051] Other ingredients In addition, the 3D printing material of this embodiment may contain other components besides the above-mentioned components (A) to (D) for the purpose of imparting desired properties. Examples of other components include rheological modifiers (including water-reducing agents, dispersants, fluidizing agents, etc., and referring to components other than component (C) mentioned above), defoaming agents, setting retarders, gas foaming substances, setting regulators, AE agents, superabsorbent polymers, rust inhibitors, water-repellent agents, antibacterial agents, colorants, antifreeze agents, anion exchangers such as hydrotalcite, humectants such as urea, and various aggregates. The amounts of these components are arbitrary. Furthermore, the components that can be included in the 3D printing material of this embodiment include various chemical admixtures shown in "Concrete Engineering 2013, Vol. 51, No. 1, pp. 40-44".
[0052] Furthermore, it is preferable that the 3D printing material of this embodiment contains a rheology modifier. By appropriately incorporating this rheology modifier, a balance can be achieved between the lamination properties and the pumpability of the 3D printing material. In one embodiment, the rheology modifier can be a polycarboxylic acid-based rheology modifier, a melamine-based rheology modifier, a naphthalene-based rheology modifier, a lignin sulfonate-based rheology modifier, a gluconate-based rheology modifier, or the like. The amount of these rheology modifiers to be blended is preferably 0.01 to 3 parts by mass, more preferably 0.03 to 1 part by mass, and most preferably 0.05 to 0.5 parts by mass, when the total mass of the binder (A) and fine aggregate (B) is 100 parts by mass. This rheology modifier may also be referred to as a "water-reducing agent," "dispersant," or "fluidizing agent."
[0053] In addition, when obtaining mortar, water is usually added in addition to the above-mentioned components (A) to (D). Furthermore, when concrete is used as a 3D printing material, coarse aggregate and the like may be added. In this embodiment, raw materials other than water may be set as the first raw material as a premix material. That is, the mixing tank 21 may be configured to produce a predetermined 3D printing material by mixing the first raw material and water.
[0054] Furthermore, the 3D printing material may be a material that is mineralized through a polymerization reaction. Typical examples of materials that are mineralized through such a polymerization reaction include geopolymer concrete. In other words, the 3D printing material in this embodiment may be a combination of an amorphous material and an alkaline solution. The amorphous material here includes fly ash and blast furnace slag. The material that is mineralized through such a polymerization reaction may also include the various components that can be included in the mortar described above.
[0055] Furthermore, the 3D printing material may be a ceramic material. Such ceramic materials are typically mineralized by firing. This ceramic material is appropriately selected from known materials that can be used in additive manufacturing processes, and may include, for example, zirconia, hydroxyapatite, aluminum nitride, alumina-reinforced zirconia, alumina, silicon nitride, cordierite, etc. Such ceramic materials may also contain the various components that can be included in the mortar as described above.
[0056] In the above description, a system was explained in which water and a premix material which is a hydraulic material are mixed. However, in other exemplary embodiments, a liquid admixture may be set as part of the raw materials to be blended. Such a liquid admixture can also be introduced from an input section used in the printing material manufacturing apparatus 2, such as the input section 214, and can be introduced into the mixing tank 21 as appropriate by opening and closing a valve.
[0057] In this context, "liquid admixture" refers to a component that is liquid at room temperature and is not water. Typically, this includes the components listed above as "Component (C)" or "Other Components" that are liquid at room temperature. In this specification, water and such liquid admixtures may collectively be referred to as "liquid raw materials."
[0058] [3D Printer 3] A 3D printer 3 is a type of industrial robot that creates three-dimensional objects by layering 3D printing material using 3D data created by a computer as a design. Here, commercially available or known devices can be used as 3D printers 3. More specifically, various shapes can be created by extruding 3D printing material (modeling material) from a nozzle equipped in the 3D printer 3.
[0059] When manufacturing such various objects using the 3D printer 3, the following process is typically followed. First, the overall shape of the object is designed in advance. Second, code to control the 3D printer 3 for printing the designed object is also designed in advance. Examples of code formats include STL, G-code, OBJ, 3MF, VRML, 3DS, and AMF. In this embodiment, the code designed in this way may include information about the 3D printing material (modeling material) (composition, specific gravity, curing speed, etc.). Examples of code formats that include such material information include 3MF and AMF, and it is possible to improve the accuracy of the shape of the actual object to be manufactured by simulating the object to be printed using the code that has been designed once.
[0060] Furthermore, during the printing process, code can be added or edited in a later stage to suit the environment or conditions of the printing site. Additionally, the code (for example, input information other than the printing path, such as printing speed) may be adjusted in real time during printing.
[0061] 2. Functional Configuration This section describes the functional configuration of this embodiment. Figure 4 is a functional block diagram showing the functions of the information processing device 1. As described above, information processing by software (stored in the memory unit 12) is concretely realized by hardware (control unit 13), and can be executed as each functional unit included in the control unit 13.
[0062] Specifically, the information processing device 1 (control unit 13) may include, as functional units, an acquisition unit 131, an adjustment unit 132, an extraction unit 133, a printing unit 134, a storage management unit 135, a display control unit 136, a reception unit 137, an estimation unit 138, a transfer unit control unit 139, and a notification unit 130. The steps that each functional unit can perform will be described below. Note that such functional units may be increased or decreased as appropriate depending on the application to which the information processing device 1 is applied.
[0063] (Acquisition part 131) The acquisition unit 131 is configured to perform the acquisition step. In the acquisition step, the acquisition unit 131 acquires various parameters. Typically, the acquisition unit 131 acquires one or more parameters relating to the physical properties of the 3D printing material during and / or after the mixing process of the 3D printing material. The acquisition unit 131 also acquires various parameters within the molding system during and / or after the mixing process of the 3D printing material. Examples of these various parameters include parameters relating to the operation of the equipment. More specific processing will be described later.
[0064] (Adjustment section 132) The adjustment unit 132 is configured to perform the adjustment step. In the adjustment step, the adjustment unit 132 adjusts the composition of at least one of several types of raw materials for the 3D printing material based on one or more acquired parameters. More specific processing will be described later.
[0065] (Removal section 133) The extraction unit 133 is configured to perform the extraction step. In the extraction step, the extraction unit 133 performs the process of extracting the mixed 3D printing material. In a specific example, the extraction unit 133 controls the valve V3 of the printing material manufacturing apparatus 2 and performs the process of extracting the mixed 3D printing material into a predetermined area (such as the extraction unit 23) inside or outside the apparatus.
[0066] (Printing Department 134) The printing unit 134 is configured to perform a printing step. In the printing step, the printing unit 134 uses the 3D printer 3 to print in a predetermined area.

Typically, the memory management unit 135 is configured to store information handled by the information processing device 1 in a memory area. This memory area may be, for example, the memory unit 12 of the information processing device 1 or the memory units of various devices and terminals, but this memory area does not necessarily have to be within the system shown in Figures 1 and 2, and the memory management unit 135 can also manage to store various information in an external memory device or the like.
[0068] (Display control unit 136) The display control unit 136 is configured to execute the display control step.

[0070] (Estimation part 138) The estimation unit 138 is configured to perform the estimation step. In the estimation step, the estimation unit 138 estimates the quality of the molded object based on one or more parameters received in the reception step and second reference information. Here, the second reference information is information that associates at least one or more parameters related to 3D printing with the quality of the molded object. More specific processing will be explained later.
[0071] (Transfer Unit Control Unit 139) The transfer unit control unit 139 is configured to execute the transfer unit control step. In the transfer unit control step, the transfer unit control unit 139 controls the transfer unit provided in the molding system of this embodiment. More typically, the transfer unit control unit 139 controls the operation of the first transfer unit and / or second transfer unit, which will be described later, based on one or more parameters acquired by the acquisition unit 131. More specific processing will be described later.
[0072] (Newspaper Section 130) The notification unit 130 is configured to execute a notification step. In the notification step, the notification unit 130 issues a warning when one or more parameters acquired by the acquisition unit 131 exceed a predetermined threshold. More specific processing will be explained later.
[0073] 3. Details of Information Processing Section 3 will explain the information processing methods performed by the molding system 200, etc., with reference to activity diagrams, etc. Figure 5 is an activity diagram showing the flow of information processing using the molding system 200, etc.
[0074] In this embodiment, first, the acquisition unit 131 acquires one or more parameters relating to the physical properties of the 3D printing material during the mixing process and / or after mixing (Activity A101).
[0075] The parameters acquired in this activity A101 can be various. That is, the parameters acquired by the acquisition unit 131 in the acquisition step may be various parameters such as viscosity, temperature, composition ratio, electrical properties, specific gravity, and optical properties of the 3D printing material. However, it is preferable to acquire one or more parameters related to the viscosity and / or temperature of the 3D printing material in the acquisition step. Acquiring such parameters makes it easier to perform the subsequent adjustment step stably. Such an acquisition step can be achieved, for example, by acquiring various parameters using various sensors and equipment provided in the printing material manufacturing apparatus 2.
[0076] Prior to the acquisition step, an extraction step may be performed. This extraction step involves extracting the mixed 3D printing material. In a typical example, this extraction step is achieved by transferring the mixed 3D printing material from the mixing tank 21 of the printing material manufacturing apparatus 2 to the extraction unit 23. In this case, the acquisition step involves acquiring one or more parameters related to the physical properties of the 3D printing material extracted in the extraction step. That is, the acquisition step is performed by acquiring the aforementioned parameters from inside the extraction unit 23 or from equipment provided in the extraction unit 23. For example, a sensor capable of detecting temperature, etc., may be provided in the extraction unit 23, and the acquisition unit 131 may acquire parameters such as temperature from the sensor. Alternatively, the system may be configured to acquire parameters such as the viscosity of the 3D printing material based on the load of the pump P1 provided in the extraction unit 23.
[0077] After the acquisition unit 131 acquires the parameters in this manner, the adjustment unit 132 adjusts the composition of at least one of the multiple raw materials of the 3D printing material based on the acquired one or more parameters (Activity A102).
[0078] Activity A102 is performed, for example, by generating various signals based on parameters acquired by the acquisition unit 131, and using these signals to perform various controls on the printing material manufacturing apparatus 2 or equipment related to the printing material manufacturing apparatus 2.
[0079] Such adjustments can take various forms, but typically, the adjustment step controls the composition of at least one of several raw materials based on one or more acquired parameters and a preset first reference information regarding 3D printing materials.
[0080] In other words, the information processing device 1 may store in advance physical properties of the 3D printing material to be used in the printing step as first reference information, and by matching the acquired parameters with the first reference information, it can calculate what adjustments should be made to the 3D printing material related to the acquired parameters. Furthermore, it may be configured to generate a predetermined signal based on such calculation results and control various devices. The first reference information here may include rule-based reference information such as lookup tables or databases. The first reference information may also be a trained model that has been trained to associate one or more parameters with the physical properties of the 3D printing material (or the mixing conditions to achieve those physical properties).
[0081] A typical example is when the viscosity parameter acquired by the acquisition unit 131 is at a higher level than the viscosity stored as the first reference information; in such cases, the method of mixing the raw materials may be controlled to lower the viscosity. There are various methods of mixing, but for example, at least one of the following may be adjusted: the amount of raw materials, the mixing speed, the mixing temperature, and the mixing position. In other words, in the example above, the valve V1 may be opened and water W may be introduced into the mixing tank 21 from the input unit 214 to reduce the viscosity of the 3D printing material. In addition, the input speed of the raw materials may be adjusted according to the state of the 3D printing material, the temperature at which the raw materials are introduced (temperature of powder and water), and the mixing position (from which position in the mixing tank 21 to introduce the materials, or, if the mixing tank 21 is divided into multiple tanks, which tank to introduce them into, etc.) may be adjusted.
[0082] Other examples of parameters acquired in the acquisition step and adjusted in the adjustment step include the following:
[0083] In other words, the acquisition unit 131 may perform a process to acquire one or more parameters relating to the physical properties of the 3D printing material based on the load when the stirring blade 211 stirs the contents of the mixing tank 21. In addition, the adjustment unit 132 may perform a process to adjust the manner in which at least one of several types of raw materials is introduced from the input unit. In other words, in such an example, the viscosity (or a similar parameter) of the 3D printing material can be acquired from the load of the stirring blade 211. The load here may be estimated by the torque value or power consumption when stirring. Furthermore, the properties of the 3D printing material in the mixing tank 21 can be adjusted by opening and closing valves V1 and V2 according to the acquired parameters.
[0084] As mentioned above, the acquisition unit 131 may perform a process to acquire one or more parameters relating to the physical properties of the 3D printing material taken out from the extraction unit 23, and the adjustment unit 132 may perform a process to adjust the manner in which at least one of several types of raw materials is introduced from the input unit. In other words, as mentioned above, parameters relating to temperature and viscosity can be acquired from sensors provided in the extraction unit 23 or from pumps P1 provided in the extraction unit 23, and the manner in which raw materials are introduced can be adjusted accordingly. For example, in the various prior art documents shown in Patent Document 3, there is no idea of acquiring parameters relating to the physical properties of the 3D printing material taken out from the extraction unit 23 and using them for control. For example, Patent Document 3 shows that various controls are performed based on the materials that are primarily mixed in the mixer, and there is no idea of providing a separate extraction unit for 3D printing material. In contrast, in the above embodiment, it is possible to acquire parameters after the 3D printing material has been taken out to the extraction unit 23, so the variety of types of parameters to be acquired naturally increases. Furthermore, this offers advantages in that it makes it easier to improve the precision of the adjustment steps and to stabilize the quality of the 3D printing material.
[0085] In addition, based on one or more parameters related to the physical properties of the 3D printing material acquired by the acquisition unit 131, the adjustment unit 132 may adjust the supply mode of the liquid admixture. For example, if the temperature of the 3D printing material is high, the viscosity of the 3D printing material is likely to decrease, and the reactivity as a hydraulic material is likely to increase, which may affect the pumpability during 3D printing. In response to this, by appropriately blending (adding) a liquid admixture that can adjust the rheology of the 3D printing material, the physical properties of the 3D printing material can be adjusted to enable good molding.
[0086] After the formulation has been adjusted as described above, the printing unit 134 prints the 3D printing material in a predetermined area (activity A103). This activity A103 is typically achieved by the printing unit 134 controlling the 3D printer 3 to print the 3D printing material in a predetermined area. As mentioned above, the 3D printer 3 uses 3D data created by a computer as a design drawing to manufacture a predetermined object. By using a 3D printing material whose formulation has been adjusted as described above, the contents of the design drawing can be faithfully reflected, and thus the desired object can be obtained stably.
[0087] Furthermore, each step (acquisition step, adjustment step, printing step) as shown in Activities A101 to A103 may be executed simultaneously. In addition, prior to Activity A103, the physical properties of the 3D printing material after the formulation has been adjusted in the adjustment step may be evaluated. Moreover, the information processing related to Activities A101 to A103 may be controlled to stabilize the properties of the 3D printing material to be used for 3D printing by performing the information processing continuously (continuously) for each frame rate of the acquisition unit 131 or each control rate of the control unit 13.
[0088] Furthermore, information regarding the history of each step performed as described above may be stored in a predetermined area by the function of the memory management unit 135.
[0089] As described above, according to the first embodiment, the configuration of the raw material mixture is adjusted based on the parameters acquired by the acquisition unit 131. The printing unit 134 performs 3D printing using the 3D printing material with such adjusted configuration, and as a result, it can be said that a stable object can be obtained.
[0090] In the first embodiment, the printing material manufacturing apparatus may be referred to as the printing material manufacturing apparatus 2A. Furthermore, the molding system 250 can be configured by including this printing material manufacturing apparatus 2A.
[0091] Figure 6 shows the overall configuration of the molding system 250. In this molding system 250, the information processing device 1 and the 3D printer 3 can adopt the same configuration as the molding system 200 described above. On the other hand, the printing material manufacturing device 2A in the molding system 250 differs from the printing material manufacturing device 2 provided in the molding system 200 in that it has the following characteristics.
[0092] In other words, the printing material manufacturing apparatus 2A shown in Figure 6 is characterized by being a combination of the first apparatus 24 and the second apparatus 25. To put it another way, the printing material manufacturing apparatus shown in Figure 6 may be an assembly of multiple apparatuses.
[0093] Here, the first apparatus 24 includes a hopper 241 into which a premix material (typically a powdered premix material) for 3D printing is fed; a first tank 242 for containing the premix material and water; a first screw 243 for receiving the premix material fed into the hopper 241 and transferring it to the first tank 242; a second screw 244 for mixing the premix material and water in the first tank 242; a motor 245 for rotating the first screw 243; and a motor 246 for rotating the second screw 244. The first apparatus 24 may also be equipped with a vibrator 247 to facilitate the downward fall of the premix material fed into the hopper 241. Furthermore, in the first apparatus 24, water W is added to the first tank 242. In other words, the system is configured so that water W is supplied to the first tank 242 by opening and closing valve V4, and in Figure 6, water W is supplied before reaching the first tank 242 during the transfer process of the premix material. In this regard, the supply location of water W is not limited to this, and for example, the system may be configured so that water W is supplied directly to the first tank 242. In Figure 6, the first screw 243 and the second screw 244 are shown as screws that enable the transfer and mixing of the premix material, but in the molding system of this embodiment, various mechanisms capable of such transfer and mixing may be employed. That is, various first mechanisms capable of transferring the premix material may be employed instead of the first screw 243, and various second mechanisms capable of stirring the premix material may be employed instead of the second screw 244.
[0094] Furthermore, the second device 25 includes a hopper 251 into which the mixture mixed in the first tank 242 of the first device 24 is introduced, a second tank 252 that receives the mixture introduced into the hopper 251, a third screw 253 that agitates the mixture in the second tank 252, a motor 254 that rotates the third screw 253, a third tank 255 that receives the mixture agitated in the second tank 252, a fourth screw 256 provided in the third tank 255 that pushes the mixture agitated in the second tank 252 to the 3D printer 3, and a motor 257 that rotates the fourth screw 256. The second device 25 may also be equipped with a vibrator 258 to facilitate the downward fall of the received mixture. In Figure 6, the third screw 253 and the fourth screw 256 are shown as screws that enable agitation and transfer of the mixture, but in the molding system of this embodiment, various mechanisms that enable such agitation and transfer may be employed. In other words, various third mechanisms capable of stirring the mixture may be used instead of the third screw 253, and various fourth mechanisms capable of transferring the mixture may be used instead of the fourth screw 256.
[0095] Furthermore, the transfer of the mixture (3D printing material) extruded by the fourth screw 256 of the second device 25 to the 3D printer 3 by the pump P1 is the same as in the molding system 200.
[0096] Furthermore, the following configuration may be adopted in such a printing material manufacturing apparatus 2A.
[0097] In other words, in the first apparatus 24, a sensor (powder sensor) capable of detecting the flow rate (powder flow rate) of the premix material may be provided downstream of the first screw 243 and before the first tank 242. Also, in a typical example, when the premix material and water are mixed, an exothermic reaction proceeds in the first tank 242, so a cooling mechanism for cooling the first tank 242 may be provided. This cooling mechanism may be provided inside the first tank 242, or it may be provided outside the first tank 242 (covering the first tank 242).
[0098] Furthermore, in the first apparatus 24, the following configuration may be adopted in order to ensure that the premix material introduced into the hopper 241 is stably supplied to the first tank 242. That is, as mentioned above, the first apparatus 24 may be equipped with a vibrator 247 to facilitate the downward dropping of the premix material introduced into the hopper 241. The vibration conditions of this vibrator 247 (vibration frequency and vibration energy) may be adjusted according to the physical properties of the premix material (composition, particle size (particle size distribution, average particle size, etc.), particle shape, density, etc.) and the environment in which the printing material manufacturing apparatus 2A is installed (temperature and humidity). It should be noted that the vibrator 247 may generate heat when vibrating, so it is preferable that the first apparatus 24 has an insulating structure to prevent the heat from propagating inside the apparatus (where the premix material moves). The receiving surface of the premix material inside the first apparatus 24 and in the hopper 241 may be subjected to surface treatment to improve the fluidity (of the powder). Furthermore, a stirrer may be provided inside the hopper 241 to suppress the solidification of the premix material. In this specification, "thermal insulation structure" refers to a structure in which a material with lower thermal conductivity than the materials constituting the various elements of the first apparatus 24 and the second apparatus 25 is interposed between the components. More specifically, a typical example of a thermal insulation structure is a structure in which a component made of resin or rubber is interposed between the vibrator 247 and the hopper 241, etc.
[0099] Furthermore, the second apparatus 25 may be provided with a cooling mechanism to cool the second tank 252 in order to remove the heat generated by stirring in the second tank 252. This cooling mechanism may be provided inside the second tank 252 or outside the second tank 252 (covering the second tank 252). Also, as mentioned above, the second apparatus 25 may be equipped with a vibrator 258 to facilitate the downward dropping of the mixture introduced into the hopper 251. The vibration conditions of the vibrator 258 (vibration frequency and vibration energy) may be adjusted according to the physical properties of the mixture (composition, viscosity, etc.) and the environment in which the printing material manufacturing apparatus 2A is installed (temperature and humidity). Since the vibrator 258 may generate heat when vibrating, it is preferable that the second apparatus 25 has an insulating structure to prevent the heat from propagating inside the apparatus (where the mixture moves).
[0100] Furthermore, since various motors are expected to generate heat when rotating, it is preferable that the various motors and / or various screws have an insulating structure to prevent such heat from propagating into the first device 24 and the second device 25.
[0101] In addition, Figure 6 shows an embodiment in which water W is added to the first apparatus 24, but the liquid admixture described above may be added to the first apparatus 24 in addition to, or instead of, water W. The amount of such liquid admixture supplied can also be controlled by opening and closing valve V4.
[0102] Various controls are performed on the printing material manufacturing apparatus 2A as described above, based on the functions of the adjustment unit 132 of the information processing apparatus 1. The control methods may vary, but typically the following controls may be performed.
[0103] In an exemplary embodiment, the adjustment unit 132 of the information processing device 1 may, as an adjustment step, separately adjust the driving conditions of the first screw 243 and the driving conditions of the second screw 244 based on one or more acquired parameters. That is, in the first device 24, the first screw 243 generally contributes to the stable supply of premix material, and the second screw 244 generally contributes to the conversion of premix material into a mixture. In the above embodiment, the equipment is controlled separately (separatedly) for these contributions. This makes it possible to balance the supply rate of raw materials and the production rate of the mixture, and makes it easier to improve the quality as a 3D printing material. Typically, the driving conditions here include the rotation conditions (rotation speed) of the screws. That is, the adjustment unit 132 can control motors 245 and 246 to adjust the rotation speed of each screw. For example, in the various prior art examples shown in Patent Document 3, there is no idea of separating the functions of the first mechanism (first screw 243) and the second mechanism (second screw 244) and using them separately for control. For example, Patent Document 3 shows an embodiment that controls up to the amount of mixture, but it does not show how to optimize the driving conditions of the mechanism used during mixing (second mechanism; second screw). In contrast, in the above embodiment, each mechanism can be properly controlled, which has the advantage of making it easier to stabilize the quality as a 3D printing material.
[0104] Furthermore, the control of the driving conditions of the first screw 243 may be based on the detected value of a sensor (powder sensor) capable of detecting the flow rate (powder flow rate) of the premix material described above. That is, one or more parameters acquired by the acquisition unit 131 of the information processing device 1 may include the detected value of the sensor (powder sensor), and the adjustment unit 132 may adjust the configuration of at least one of the premix material and water and / or liquid admixture based on at least the detected value of the sensor (powder sensor). Specific means of adjusting the configuration of the premix material include controlling the driving conditions of the first screw 243 and adjusting the blending amount. Typically, the driving conditions here refer to the screw rotation conditions (speed of rotation). That is, the adjustment unit 132 can control the motor 245 and adjust the speed of rotation of the first screw 243. On the other hand, specific means of adjusting the configuration of the water and liquid admixture (liquid raw material) include adjusting the degree of opening and closing of the valve V4. For example, in the various prior art examples shown in Patent Document 3, there is no idea of utilizing the detected values obtained from such powder sensors for equipment control. In contrast, in the above embodiment, the premix material being transported by the first mechanism can be measured immediately, which makes it easier to improve the control of the preparation step and, as a result, makes it easier to stabilize the quality as a 3D printing material.
[0105] In an exemplary embodiment, the adjustment unit 132 of the information processing device 1 may, as an adjustment step, adjust the supply mode of water and / or liquid admixture to the first tank 242 based on one or more acquired parameters. That is, in the first apparatus 24, the premix material and liquid raw material are mixed in the first tank 242, but in the embodiment described above, at least the supply mode of the liquid raw material is controlled to ensure stable mixing. The control of the supply mode here may involve controlling one or more selected from the group consisting of the amount of liquid raw material supplied, the supply rate of the liquid raw material, the temperature of the liquid raw material, the supply pressure of the liquid raw material, the supply position of the liquid raw material, and the jet shape of the liquid raw material. In a more specific example, this includes increasing the supply rate of water or liquid admixture or decreasing the temperature of the supplied water or liquid admixture as the internal temperature of the first tank 242 rises. Separately, the aforementioned supply mode of liquid raw material may be adjusted based on the physical properties of the mixture present in the first tank 242 or the second apparatus 25. The amount and rate of liquid raw material supply can typically be adjusted by adjusting the degree of opening and closing of valve V4. The temperature of the liquid raw material may be controlled by a temperature control mechanism (such as a cooling mechanism) provided in the liquid raw material flow path (not shown). Figure 6 shows a configuration in which the supply position of the liquid raw material (water W) is fixed, but the supply position of the liquid raw material may be adjusted, for example, as follows. That is, multiple supply ports for the liquid raw material to the first tank 242 of the first device 24 may be provided. In other words, the adjustment unit 132 may control which of these multiple supply ports from which the liquid raw material is supplied, thereby enabling position-selective supply of the liquid raw material. In this case, the supply of the liquid raw material is not limited to one port, and the liquid raw material may be supplied from multiple supply ports. In a more specific example, it is also possible to control the mixing process by determining the supply position of the liquid raw material based on the physical properties of the mixture in the first tank 242, and supplying the liquid raw material from that supply position at a predetermined pressure, thereby ensuring proper mixing. Furthermore, in this embodiment, the jet shape of the liquid raw material may be controlled by the function of the adjustment unit 132. Control of the jet shape here includes controlling the spray angle, the diffusion angle during spraying, and the fineness of the spray particles of the liquid raw material.Such control can be achieved, for example, by the adjustment unit 132 changing the shape of the liquid raw material supply port.
[0106] In an exemplary embodiment, the adjustment unit 132 of the information processing device 1 may, as an adjustment step, adjust the driving conditions of the third screw 253 and / or the fourth screw 256 in the second device 25 based on one or more acquired parameters. That is, the third screw 253 generally contributes to improving the stability of the mixture when it is pumped by the pump P1 by stirring the mixture, and the fourth screw 256 generally contributes to properly transferring the stirred mixture to the pump P1. In other words, as an adjustment step, the adjustment unit 132 may control the stable supply of the mixture (3D printing material) to the pump P1 by adjusting the driving conditions of at least one of the third screw 253 and the fourth screw 256 in the second device 25 based on one or more acquired parameters. Typically, the driving conditions here include the rotation conditions (rotation speed) of the screws. That is, the adjustment unit 132 can control motors 254 and 257 to adjust the rotation speed of the third screw 253 and the fourth screw 256.
[0107] In an exemplary embodiment, the adjustment unit 132 of the information processing device 1 may, as an adjustment step, adjust the driving conditions (vibration conditions) of the vibrator 258 in the second device 25 based on one or more acquired parameters. As mentioned above, the vibrator 258 has the function of making it easier for the mixture introduced into the second device 25 to fall downward. That is, the adjustment unit 132 may control the stable supply of the mixture (3D printing material) to the pump P1 by adjusting the vibration conditions (vibration frequency and vibration energy) of the vibrator 258. The adjustment of the driving conditions (vibration conditions) here may include adjusting the vibration frequency and vibration energy.
[0108] [Second Embodiment: Estimation Method for Estimating the Quality of a Molded Object] Next, a second embodiment will be described. The estimation method according to the second embodiment is shown below. A method for estimating the quality of a molded object, It comprises a reception step and an estimation step, In the aforementioned reception step, one or more parameters related to 3D printing are accepted. In the estimation step, the quality of the molded object is estimated based on one or more parameters received in the reception step and the second reference information. Herein, the second reference information is an estimation method in which information relating at least one parameter related to 3D printing and the quality of the printed object is associated.
[0109] The estimation method described above can be realized by the functions of the information processing device 1 as shown in the first embodiment. That is, the reception unit 137 and estimation unit 138 provided in the information processing device 1 perform the reception step and estimation step described above, thereby realizing the estimation method of the second embodiment. The information processing device 1 itself, which includes the reception unit 137 and the estimation unit 138, or a group of elements including the information processing device 1 plus related equipment and facilities, may be referred to as an "estimation system" capable of executing the estimation method.
[0110] This estimation method will be explained with reference to an activity diagram. Figure 7 is an activity diagram showing the flow of information processing performed by the information processing device 1. While each embodiment from the second embodiment onward may adopt the various features described in the previously mentioned embodiments, for the sake of simplification, this specification omits explanations of overlapping parts.
[0111] In other words, in the estimation method of the second embodiment, the reception unit 137 first receives one or more parameters related to 3D printing (activity A201).
[0112] In Activity A201, the parameters received by the reception unit 137 may be parameters related to various processes related to 3D printing.
[0113] Typically, 3D printing is, Process (1) Design of the 3D object Process (2) Manufacturing of 3D printing materials Process (3) Fabrication using a 3D printer Process (4) Curing of the molded object Various processes are carried out as described above, and the parameters accepted in the second embodiment may be parameters related to (or managed by) these various processes.
[0114] For example, in process (1), information regarding the 3D printing material (modeling material) to be used (composition, specific gravity, curing speed, etc.) is managed in addition to the mechanical parameters related to the object to be designed. In the reception step, the relevant parameters can be received in relation to process (1).
[0115] Furthermore, in step (2), in the first embodiment, the acquisition unit 131 can manage various parameters that can be acquired, and the reception unit 137 can receive such parameters.
[0116] Furthermore, in process (3), parameters (nozzle extrusion amount, extrusion speed, etc.) used to control the 3D printer (3D printer 3, etc.) are managed and used. In the reception step, the relevant parameters can be received in relation to process (3).
[0117] Furthermore, in process (4), the curing conditions of the molded object (temperature, humidity, curing time, etc.) are controlled. In the reception step, the relevant parameters for process (4) can be received.
[0118] The reception step may involve the reception unit 137 actively acquiring various parameters, or it may involve the reception unit passively accepting input of various parameters through the user's terminal operation, etc.
[0119] As described above, after the receiving unit 137 receives the parameters, the estimation unit 138 estimates the quality of the molded object based on one or more parameters received in the receiving step and the second reference information (Activity A202).
[0120] The second reference information used in Activity A202 is information that associates at least one parameter related to 3D printing with the quality of the printed object. Here, such second reference information may include rule-based reference information such as lookup tables or databases, or it may be a trained model that has been trained to associate one or more parameters related to 3D printing with the quality of the printed object.
[0121] Here, "quality of the printed object" refers to the quality of the printed object corresponding to a previously performed 3D print, and is, for example, the quality evaluated by a test specimen produced in a certain process. Furthermore, the quality of the printed object thus evaluated is associated with various parameters used to produce the printed object (typically the various parameters related to the aforementioned processes (1) to (4)). The second reference information used in the second embodiment is generated by associating these parameters.
[0122] In other words, in the estimation step of the second embodiment, the quality of the 3D printed object can be estimated based on one or more parameters related to 3D printing received by the receiving unit 137 and the second reference information, without requiring evaluation of the 3D printed object (molded object) received in the receiving step.
[0123] Furthermore, if the second reference information includes a rule base, the received parameters should be matched with the second reference information, and information regarding the quality of the printed object should be output. If the second reference information is a pre-trained model, the received parameters should be input into the pre-trained model, and information regarding the quality of the printed object should be output.
[0124] Furthermore, the quality of the molded object estimated as described above may be displayed on the display unit 14 of the information processing device 1 or the like by the function of the display control unit 136. In addition, the information processing device 1 may be configured to print a printed document showing the quality of the molded object estimated as described above (a printing device not shown may be controlled by the control of the information processing device 1).
[0125] Furthermore, the second reference method may be updated as appropriate based on one or more parameters related to 3D printing and the quality of the molded object (e.g., actual measurement results (actual values)) obtained when the reception step and estimation step are performed as described above. Also, as in the first embodiment, information regarding the history obtained when the reception step and estimation step are performed may be stored in a predetermined area based on the function of the memory management unit 135.
[0126] In the second embodiment, the quality of the molded object can be efficiently estimated based on the parameters received by the receiving unit 137.
[0127] [Third Embodiment: Molding System] Next, the third embodiment will be described. The molding system according to the third embodiment is shown below. It is a molding system, The system comprises a manufacturing system for producing 3D printing material by mixing multiple types of raw materials, a 3D printer configured to print the 3D printing material produced by the manufacturing system, and a control unit. The aforementioned 3D printer is A first transfer unit that receives and transfers the 3D printed material manufactured by the aforementioned manufacturing system, A second transfer unit receives and transfers the 3D printing material transferred from the first transfer unit, The system comprises a nozzle for printing 3D printing material transferred from the second transfer unit onto a predetermined area, The control unit is configured to perform an acquisition step and a transfer unit control step, In the acquisition step, one or more parameters are acquired from the manufacturing system and / or the 3D printer during the mixing process of the 3D printing material and / or after mixing. The molding system, in the transfer unit control step, controls the operation of the first transfer unit and / or the second transfer unit based on the acquired one or more parameters.
[0128] A typical example of such a molding system will be explained with reference to the figures. Figure 8 shows the overall configuration of the molding system 300 in the third embodiment. As shown in Figure 8, the molding system 300 comprises an information processing device 1, a printing material manufacturing device 2, and a 3D printer 3. Here, the information processing device 1 may have the same configuration as the information processing device 1 shown in each of the embodiments described above. Note that the printing material manufacturing device 2 in Figure 8 differs from the one shown in the first embodiment in that it does not have a pump P1. In this regard, in the molding system 300 shown in Figure 8, the manufactured 3D printing material is described as being transported by a transfer mechanism (transfer unit) provided in the 3D printer 3, but in the 3D printer of the third embodiment, it can be called a "3D printer" including a configuration that can accept the 3D printing material manufactured by the printing material manufacturing device 2 (manufacturing system). That is, in the example of the molding system 200 shown in Figure 2, the pump P1 may be referred to as part of the configuration of the 3D printer 3.
[0129] Furthermore, the printing material manufacturing apparatus 2 may also be referred to as a "manufacturing system" since it is configured to communicate with the information processing apparatus 1. Note that the specific configuration of the printing material manufacturing apparatus 2 (manufacturing system) is not limited to that shown in Figure 8, and a different configuration may be adopted as appropriate. That is, the printing material manufacturing apparatus 2 portion shown in Figure 8 may be replaced with the printing material manufacturing apparatus 2A shown in Figure 7.
[0130] In this embodiment, the 3D printer 3 may have the configuration shown in Figure 9. Figure 9 is a diagram showing an overview of the 3D printer 3 in the third embodiment. The 3D printer 3 shown in Figure 9 includes a first transfer unit TS1 that receives and transfers 3D printing material manufactured by the printing material manufacturing apparatus 2 (manufacturing system), a second transfer unit TS2 that receives and transfers the 3D printing material transferred from the first transfer unit TS1, and a nozzle NZ that prints the 3D printing material transferred from the second transfer unit TS2 in a predetermined area. The 3D printer 3 shown in Figure 9 also includes a first transfer path TR1 through which the 3D printing material transferred by the first transfer unit TS1 passes, and a second transfer path TR2 through which the 3D printing material transferred by the second transfer unit TS2 passes. The nozzle NZ is configured so that its position is controlled by the printing unit 134 of the information processing device 1, thereby enabling printing in a predetermined area. The 3D printer 3 may also have configurations other than those shown in Figure 9. For example, it may include other transfer units (third transfer unit) not shown. Furthermore, one or more pressure sensors may be installed inside the first transport path TR1 or the second transport path TR2 to detect the pressure inside the transport path. Also, one or more sensors (flow sensors) may be installed inside the first transport path TR1 or the second transport path TR2 to detect the speed at which the 3D printed material moves inside the transport path.
[0131] In this embodiment, the first transfer unit TS1 is selected from known configurations capable of receiving and transferring 3D printing material. Typically, the first transfer unit TS1 is configured to pump 3D printing material. More specifically, the first transfer unit TS1 may be a pump. Examples of pumps that can be used include, but are not limited to, rotary pumps, gear pumps, diaphragm pumps, bellows pumps, tubing pumps, roller pumps, syringe pumps, pulsating pumps, and non-pulsating pumps, and various other pumps may be used (the pump used in the first transfer unit TS1 may be a pump equipped with a hopper). The amount of 3D printing material that the first transfer unit TS1 can transfer per unit of time may be appropriately set according to the properties of the 3D printing material, as well as the contents of the first transfer path TR1, the second transfer path TR2, and the second transfer unit TS2.
[0132] In this embodiment, the second transfer unit TS2 is selected from known configurations capable of receiving and transferring 3D printing material. Typically, the second transfer unit TS2 is configured to pump 3D printing material. More specifically, the second transfer unit TS2 may be a pump. Examples of pumps that can be used include, but are not limited to, rotary pumps, gear pumps, diaphragm pumps, bellows pumps, tubing pumps, roller pumps, syringe pumps, pulsating pumps, and non-pulsating pumps. (Note that the pump used in the second transfer unit TS2 may be a pump equipped with a hopper.) On the other hand, since the second transfer unit TS2 is located close to the nozzle NZ, it is preferable that it is configured to precisely transfer (discharge) the 3D printing material. From this viewpoint, it is preferable that the second transfer unit TS2 is a non-pulsating pump. The amount of 3D printing material that the second transfer unit TS2 can transfer per unit of time may be set appropriately according to the properties of the 3D printing material, as well as the contents of the first transfer path TR1, the second transfer path TR2, and the first transfer unit TS1.
[0133] In this embodiment, the first transfer path TR1 is the path through which the 3D printing material to be transferred by the first transfer unit TS1 passes. This first transfer path TR1 may be an open system or a closed system. For example, the first transfer path TR1 is a closed system, and together with the transfer outlet of the first transfer unit TS1 and the transfer inlet of the second transfer unit TS2, it forms a predetermined closed space. In this way, when the first transfer path TR1 constitutes a closed system, the inside of the first transfer path TR1 may become pressurized during the process of transferring the 3D printing material. The pressure load (feeding pressure) of the first transfer unit TS1 during the transfer process of the 3D printing material can be appropriately set according to conditions such as the length of the first transfer path TR1. For example, when defining the pressure load per unit length (m) of the first transfer path TR1 by the first transfer unit TS1, this pressure load per unit length (m) of the first transfer path TR1 is preferably in the range of 0.10 to 0.42 MPa / m, more preferably in the range of 0.14 to 0.33 MPa / m, and even more preferably in the range of 0.18 to 0.24 MPa / m. The above-mentioned pressure load per unit length (m) of the first transfer path TR1 by the first transfer unit TS1 is defined as the value obtained by dividing the pressure (pumping pressure) that the first transfer unit TS1 applies to the first transfer path TR1 by the length of the first transfer path TR1. Specifically, taking the case where the length of the first transport path TR1 is 10 m as an example, the pressure that the first transport unit TS1 applies to the first transport path TR1 (internal pressure of the first transport path TR1) is preferably in the range of 1 to 4.2 MPa, more preferably in the range of 1.4 to 3.3 MPa, and even more preferably in the range of 1.8 to 2.4 MPa. By setting it within this range, the 3D printing material can be flowed appropriately according to the length of the first transport path TR1.
[0134] In this embodiment, the first transfer path TR1 may be provided with a mechanism for adjusting the internal pressure of the first transfer path TR1. That is, although not shown in Figure 9, the first transfer path TR1 may be connected to an accumulator to make it easier to keep the internal pressure of the first transfer path TR1 within a predetermined range. This accumulator can store the pressure generated by the 3D printed material when the 3D printed material is sealed inside the first transfer path TR1. For example, in the various prior art documents shown in Patent Document 4, the idea of providing such an accumulator between the transfer sections is not shown.
[0135] In this regard, as mentioned above, in typical cases, a pressure sensor can be installed inside the first transfer path TR1. However, if the volume of the first transfer path TR1 is large, the control of the transfer unit based on the detected value of this pressure sensor may not be sufficient to control the internal pressure. From this point of view, by connecting an accumulator to the first transfer path TR1, the internal pressure of the first transfer path TR1 can be further optimized. Furthermore, by connecting an accumulator to the first transfer path TR1 in this way, the types of equipment that can be applied to the first transfer unit TS1 and the second transfer unit TS2 can be expanded, which can also contribute to improving the robustness of the 3D printer 3.
[0136] Furthermore, the 3D printing material used in the molding system of the third embodiment may contain the admixture (C) that imparts thixotropy as shown in the first embodiment. By using the internal pressure of the first transfer path TR1 described above, while the 3D printing material contains the admixture (C) that imparts thixotropy, the following effects can be achieved. That is, when the thixotropy of the 3D printing material is high, the viscosity of the material tends to increase during the process of staying in the first transfer path TR1. In contrast, by using the internal pressure of the first transfer path TR1 as described above, the second transfer section TS2 can operate more stably, and as a result, the molding process can be stabilized.
[0137] Furthermore, the first transport path TR1 may be tubular (hose-like). The material constituting this tube (hose) can be appropriately selected, and may be, for example, resin, metal, ceramics, etc.
[0138] Furthermore, the length of the first transfer path TR1 (the distance from the exit of the first transfer unit TS1 to the entrance of the second transfer unit TS2) can be set as appropriate. On the other hand, from the viewpoint of performing the molding process stably, an upper limit may be set for the length of the first transfer path TR1. For example, the length of the first transfer path TR1 may be 50m or less, 45m or less, 40m or less, 35m or less, or 30m or less. Also, the length of the first transfer path TR1 may be 50cm or more, 1m or more, or 3m or more.
[0139] Furthermore, the volume of the first transfer path TR1 when it constitutes a closed system can also be set as appropriate. For example, the volume of the first transfer path TR1 is 3000 cm³. 3 More than 18000cm 3 The range may be as follows: 4500cm 3 More than 13000cm 3 The range may be as follows: 7000 cm 3 More than 8000cm 3 The range may be as follows. By setting it within this range, the printing material transferred from the printing material manufacturing apparatus 2 can be stored appropriately, and it becomes easier to discharge printing material of stable quality from the nozzle NZ.
[0140] In this embodiment, the second transport path TR2 is the path through which the 3D printing material transported by the second transport unit TS2 passes. This second transport path TR2 may be an open path or a closed path. For example, if the tip of the nozzle NZ is open, the second transport path TR2 is an open path. On the other hand, if the nozzle NZ is configured to be openable and closable, the closed nozzle NZ and the transport outlet of the second transport unit may form a closed system.
[0141] The pressure load (feeding pressure) of the second transfer unit TS2 during the 3D printing material transfer process can be appropriately set according to conditions such as the length of the second transfer path TR2. For example, the feeding pressure by the second transfer unit TS2 is preferably in the range of 0.1 to 5 MPa, more preferably in the range of 0.15 to 4 MPa, and even more preferably in the range of 0.2 to 2 MPa. By setting it within this range, the 3D printing material can be flowed appropriately within the second transfer path TR2. The relationship between the pressure load (feeding pressure) by the first transfer unit TS1 and the pressure load (feeding pressure) by the second transfer unit TS2 can be appropriately set, but it is preferable to adopt a configuration in which the pressure load by the first transfer unit TS1 is greater than the pressure load by the second transfer unit TS2. This makes it easier to stabilize the entire molding process.
[0142] Furthermore, the length of the second transfer path TR2 (the distance from the exit of the second transfer unit TS2 to the entrance of the nozzle NZ) can be set as appropriate. On the other hand, from the viewpoint of performing the molding process stably, an upper limit may be set for the length of this second transfer path TR2. For example, the length of the second transfer path TR2 may be 15m or less, 12m or less, 10m or less, 8m or less, or 5m or less. Also, the length of the second transfer path TR2 may be 10cm or more, 15cm or more, or 20cm or more.
[0143] Furthermore, the volume of the second transfer path TR2 when it constitutes a sealed system can also be set as appropriate. The range of the volume of this second transfer path TR2 is determined, for example, according to the properties of the printing material.
[0144] Furthermore, if the second transfer unit TS2 is a pump equipped with a hopper, the pressure inside the hopper (internal pressure) can also be set as appropriate. For example, the pressure inside the hopper of the second transfer unit TS2 may be in the range of 0.1 MPa to 1.5 MPa, 0.2 MPa to 1 MPa, or 0.4 MPa to 0.6 MPa. By setting it within such a range, the molding process can be carried out without placing an excessive load on the second transfer unit TS2.
[0145] In this embodiment, the relationship between the length of the first transport path TR1 and the length of the second transport path TR2 may be set as appropriate. On the other hand, the length of the first transport path TR1 may be longer than the length of the second transport path TR2. For example, when the length of the first transport path TR1 is defined as L1 and the length of the second transport path TR2 as L2, L1 / L2 may be 1.5 or more, 3 or more, or 5 or more. Setting it to such a value makes it easier to extrude printing material of stable quality from the nozzle NZ.
[0146] In this embodiment, the relationship between the volume of the first transport path TR1 and the volume of the second transport path TR2 may be set as appropriate. On the other hand, the volume of the first transport path TR1 may be set to be larger than the volume of the second transport path TR2. For example, when the volume of the first transport path TR1 is defined as V1 and the volume of the second transport path TR2 as V2, V1 / V2 may be 1.5 or more, 3 or more, or 5 or more. Setting it to such a value makes it easier to extrude printing material of stable quality from the nozzle NZ.
[0147] The following describes a molding process (which may also be called a "molding method") using the molding system 300 described above. Figure 10 is an activity diagram showing the flow of information processing using the molding system 300, etc. In the molding process of the third embodiment, the control unit 13 of the information processing device 1 performs a predetermined molding by executing an acquisition step and a transfer unit control step. Here, in the acquisition step, one or more parameters are acquired from the manufacturing system and / or 3D printer during and / or after the mixing process of the 3D printing materials, and in the transfer unit control step, the operation of the first transfer unit TS1 and / or the second transfer unit TS2 is controlled based on the acquired one or more parameters.
[0148] In other words, in the molding process of this embodiment, first, the acquisition unit 131 of the information processing device 1 acquires one or more parameters from the manufacturing system and / or 3D printer during and / or after the mixing process of the 3D printing materials (activity A301). These parameters may be various parameters relating to the printing material manufacturing device 2 and the 3D printer 3, but in one embodiment, they include parameters relating to the driving of equipment within the manufacturing system during and / or after the mixing process of the 3D printing materials. Here, equipment within the manufacturing system is, for example, equipment that transports raw materials or 3D printing materials. That is, taking the molding system 300 in Figure 8 as an example, the acquisition unit 131 of the information processing device 1 may be configured to acquire signals from valves (valves V1, V2, V3) and motors 212 provided in the printing material manufacturing device 2, thereby enabling the acquisition of parameters relating to the driving status of the printing material manufacturing device 2. Furthermore, parameters relating to the driving of equipment within the manufacturing system may be acquired based on signals from equipment and sensors not shown in Figure 8. The parameters acquired by the acquisition unit 131 may include parameters relating to the physical properties of the 3D printing material during the mixing process and / or after mixing. Examples of these physical property parameters include the various parameters described in the first embodiment.
[0149] On the other hand, the acquisition unit 131 of the information processing device 1 may acquire one or more parameters from the 3D printer 3. Examples of parameters that can be acquired from the 3D printer 3 include parameters relating to the driving of the first transfer unit TS1, the second transfer unit TS2, and the nozzle NZ, as well as parameters relating to the pressure inside the first transfer path TR1 and the second transfer path TR2, parameters relating to the movement speed of the 3D printed material moving inside the first transfer path TR1 and the second transfer path TR2, and parameters relating to the temperature of each element constituting the 3D printer 3.
[0150] Next, in the molding process of this embodiment, the transfer unit control unit 139 controls the operation of the first transfer unit TS1 and / or the second transfer unit TS2 based on one or more acquired parameters (Activity A302). Based on the functions of these transfer units, the printing unit 134 prints the 3D printing material in a predetermined area (Activity A303).
[0151] The method by which the transfer unit control unit 139 controls each transfer unit may vary, but typically, in the transfer unit control step, the operation of the first transfer unit TS1 and / or the second transfer unit TS2 is controlled based on one or more acquired parameters and a preset third reference information relating to the molding process.
[0152] In other words, the information processing device 1 may store process values related to the 3D printing material to be used in the printing step as third reference information in advance, and by matching the acquired parameters with the third reference information, it can calculate what kind of control should be applied to the first transfer unit TS1 and / or the second transfer unit TS2 when executing the molding process. That is, it may be configured to generate a predetermined signal based on such calculation results and control each transfer unit. The third reference information here may include rule-based reference information such as a lookup table or a database. Furthermore, the third reference information may be a trained model that has been trained by associating one or more parameters with conditions related to the molding process.
[0153] In this embodiment, it is preferable that both the first transfer unit TS1 and the second transfer unit TS2 are controlled by the transfer unit control unit 139. Patent Document 4 shows an embodiment in which only the rotational speed of the drive motor of the screw located at the tip is adjusted based on the detection result (see Patent Document 4, paragraph 0017, etc.). In other words, Patent Document 4 does not have the concept of precisely controlling the first transfer unit TS1 that transfers the 3D printing material to the second transfer unit TS2. In contrast, by adopting the above embodiment in the present application, multiple types of transfer units can be appropriately controlled, making it easier to stabilize the quality of the printing material in the molding process and further improve the molding accuracy in the 3D printing process.
[0154] In one embodiment, the acquisition unit 131 may acquire parameters related to the drive of the second transfer unit TS2, and then the transfer unit control unit 139 may control the first transfer unit TS1. Here, the parameters acquired by the acquisition unit 131 from the second transfer unit TS2 may be set as appropriate, but typically include the rotation speed of the pump when the second transfer unit TS2 is a pump. That is, in one embodiment, the transfer unit control unit 139 can control the drive conditions of the first transfer unit TS1 (typically the pump rotation speed when the first transfer unit TS1 is a pump) based on the pump rotation speed of the second transfer unit TS2 acquired by the acquisition unit 131. However, even in this embodiment, the parameters acquired by the acquisition unit 131 may include parameters other than those related to the drive of the second transfer unit TS2 as described above. That is, in addition to the parameters related to the drive of the second transfer unit TS2, other parameters such as the internal pressure of the first transfer path TR1 may be acquired, and then the control conditions of the first transfer unit TS1 may be determined and control performed.
[0155] From a different perspective, the control of the first transfer unit TS1 may be as follows: The first transfer unit TS1 may be feedback controlled (PID control, etc.) according to the internal pressure of the first transfer path TR1. That is, the acquisition unit 131 may acquire the internal pressure of the first transfer path TR1 as a parameter based on information received from various sensors, and the transfer unit control unit 139 may control the driving conditions of the first transfer unit TS1 accordingly. However, depending on the physical properties of the 3D printing material used, it may not be possible to properly detect pressure fluctuations in the first transfer path TR1. For this reason, it is also effective for the transfer unit control unit 139 to control the driving of the first transfer unit TS1 using parameters related to the driving of the second transfer unit TS2 in addition to, or instead of, the internal pressure of the first transfer path TR1.
[0156] To explain from another perspective, the acquisition unit 131 may acquire parameters inside the first transport path TR1, and then the transport unit control unit 139 may control the drive of at least one of the first transport unit TS1 and the second transport unit TS2. Examples of parameters inside the first transport path TR1 include the internal pressure of the first transport path TR1 and the movement speed of the 3D printed material moving inside the first transport path TR1. In other words, the drive of at least one of the first transport unit TS1 and the second transport unit TS2 may be controlled based on a detected value detected by a predetermined sensor. Here, the detected value acquired by the sensor is not limited to one, and the drive of at least one of the first transport unit TS1 and the second transport unit TS2 may be controlled based on multiple detected values. Control based on multiple detected values includes, for example, control based on the difference between multiple detected values. Typically, within the first transport path TR1, it is possible to obtain detection values from a pressure sensor near the first transport unit TS1 and a pressure sensor near the second transport unit TS2, and determine the driving conditions of the first transport unit TS1 and / or the second transport unit TS2 from the difference between these values. Note that the internal parameters of the first transport path TR1 may be obtained by elements other than sensors provided inside the first transport path TR1. For example, since the internal pressure of the first transport path TR1 is highly dependent on the driving conditions of the first transport unit TS1, various controls may be performed based on the driving conditions of the first transport unit TS1. This method of obtaining the internal parameters of the first transport path TR1 is also unprecedented in the prior art, such as in Patent Document 4.
[0157] As described above, the transfer unit control unit 139 controls the first transfer unit TS1 and / or the second transfer unit TS2, and then the printing unit 134 prints the 3D printing material in a predetermined area. The method for printing the 3D printing material in a predetermined area is the same as that shown in the first embodiment.
[0158] Furthermore, each step shown in Activities A301 to A303 (acquisition step, transfer unit control step, printing step) may be executed simultaneously. In addition, the information processing related to Activities A301 to A303 may be controlled to stabilize the molding process by being performed continuously (continuously) for each frame rate of the acquisition unit 131 or each control rate of the control unit 13.
[0159] In the third embodiment, the molding system controls the transfer mode of the 3D printing material in the 3D printer 3 by parameters related to the printing material manufacturing apparatus 2 (manufacturing system). This enables a stable molding process.
[0160] [Fourth Embodiment: Manufacturing System for 3D Printing Materials] Next, the fourth embodiment will be described. The manufacturing system for 3D printing materials according to the fourth embodiment is shown below. A manufacturing system for 3D printing materials made by mixing multiple types of raw materials, Equipped with a control unit, The control unit is configured to perform an acquisition step and a notification step, In the acquisition step, one or more parameters relating to the operation of equipment in the manufacturing system during the mixing process and / or after mixing of the 3D printing material are acquired. In the notification step, the manufacturing system issues a warning when one or more of the acquired parameters exceed a predetermined threshold.
[0161] Figure 11 is an activity diagram showing the information processing flow in the fourth embodiment. While not limited thereto, the 3D printing material manufacturing system of the fourth embodiment may have a configuration similar to, for example, the manufacturing system 100 shown in Figure 1. The information processing that can be realized by the manufacturing system 100 shown in Figure 1 will be described below.
[0162] In other words, in the fourth embodiment, first, the acquisition unit 131 acquires one or more parameters related to the driving of equipment in the manufacturing system during and / or after the mixing process of the 3D printing material (activity A401). As described in the third embodiment, equipment in the manufacturing system is, for example, equipment that transports raw materials or 3D printing material. In other words, taking the manufacturing system 100 in Figure 1 as an example, the acquisition unit 131 of the information processing device 1 may be configured to acquire signals from valves (valves V1, V2, V3) and motors 212 provided in the printing material manufacturing device 2, thereby enabling the acquisition of parameters related to the driving status of the printing material manufacturing device 2.
[0163] Next, the notification unit 130 issues a warning (activity A402) when one or more parameters acquired by the acquisition unit 131 exceed a predetermined threshold. That is, the storage unit 12 of the information processing device 1 may store the type of parameter and the threshold value for that parameter in association with each other. The information processing device 1 may also determine whether or not to issue a warning by comparing the parameters acquired by the acquisition unit 131 with the stored threshold values.
[0164] The method of outputting warnings can be selected as appropriate. For example, based on the functions of the display control unit 136, it is possible to display visual information via the display unit 14 of the information processing device 1 indicating that the operating status of the printing material manufacturing apparatus 2 is unsatisfactory. In this embodiment, it is also possible to warn that a part in the manufacturing system 100 needs to be replaced. In addition, based on the functions of the control unit 13, various information related to the above-mentioned warnings can be output as audio.
[0165] Furthermore, if the acquisition unit 131 continuously acquires signals from the printing material manufacturing apparatus 2, the notification unit 130 may use a sudden change in the continuously acquired state quantity as a trigger for issuing a warning. In addition, warning conditions can be set as appropriate according to the user's needs.
[0166] In the fourth embodiment, the manufacturing system is controlled so that predetermined warnings are issued based on parameters related to the printing material manufacturing apparatus 2 (manufacturing system). This makes it easier to manage the process and enables a stable molding process.
[0167] [Fifth Embodiment: Molding System] Next, the fifth embodiment will be described. The molding system according to the fifth embodiment is shown below. A 3D printing system configured to print 3D printing materials, Control unit and A first transfer unit that receives and transfers the aforementioned 3D printing material, A second transfer unit receives and transfers the 3D printing material transferred from the first transfer unit, The system comprises a nozzle for printing 3D printing material transferred from the second transfer unit onto a predetermined area, A molding system in which the first transfer unit and / or the second transfer unit are controlled by the control unit.
[0168] Although not limited thereto, the molding system of this embodiment may include a 3D printer 3 shown in Figure 9 and an information processing device 1 configured to communicate with the 3D printer 3. In other words, the molding system of the fifth embodiment may also have the same configuration of the 3D printer 3 (each transport unit, each transport path, nozzle, etc.) as the molding system described in the third embodiment.
[0169] On the other hand, in the fifth embodiment, the information processing device 1 does not necessarily have to acquire parameters from the manufacturing system, and the 3D printing material transferred to the first transfer unit TS1 does not have to be manufactured by the printing material manufacturing device 2. In other words, in the molding system of the fifth embodiment, the first transfer unit TS1 does not need to be connected to the printing material manufacturing device 2, and may be configured to accept and transfer pre-prepared 3D printing material. For example, the first transfer unit TS1 in the fifth embodiment may be a cartridge or hopper that can accept and transfer pre-prepared 3D printing material. Furthermore, if the first transfer unit TS1 and / or the second transfer unit TS2 are controlled by the control unit 13 of the information processing device 1, this control may be based on content other than the aforementioned parameters. In a typical example, in the molding system of the fifth embodiment, the acquisition unit 131 may acquire signals based on manual operation from the operator (user), and each transfer unit may be controlled based on said signals.
[0170] As described above, the molding system of the fifth embodiment is configured such that the first transfer unit TS1 and / or the second transfer unit TS2 can be controlled by a predetermined control unit, making it easier to achieve a stable molding process.
[0171] [others] The following describes variations of the information processing methods for the aforementioned manufacturing system 100, molding system 200, molding system 250, molding system 300, etc.
[0172] Although the embodiments described above were explained as comprising a manufacturing system 100, a molding system 200, a molding system 250, and a molding system 300, a program may be provided to cause at least one computer to execute each step of the method for manufacturing 3D printing materials and the method for manufacturing molded objects.
