Embodiment for Carrying Out the Invention

[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram for explaining an embodiment of a method for manufacturing a building according to the present invention.

[0010] In FIG. 1, here, a building (particularly a residential building) manufactured by a 3D printing layered manufacturing method will be referred to as a "3D printer house" and will be denoted by reference numeral 100. The 3D printing layered manufacturing method is a manufacturing method in which, based on digital data of a building, materials such as concrete, mortar, or ceramic output from the head of a 3D printer (see FIG. 2) described later are laminated in a predetermined direction to manufacture at least a part of the building (here, the frame 5 described later).

[0011] A "3D printer" is a device that forms one layer by outputting a material onto a predetermined surface parallel to the XY plane based on a 3D model (the above-described digital data, which is here referred to as 3D house data. The 3D house data also includes data related to the frame 5 described later), and then further moves the head in a substantially Z direction (substantially vertical direction) to print the next layer so as to stack it on the said layer (3D printing layered manufacturing method). The 3D printer will be denoted by reference numeral 3 (see FIG. 2). By using the 3D printer 3, it becomes possible to manufacture (print) a 3D printer house 100 having a wall surface such as a "sphere" as shown in FIG. 1, for example.

[0012] The 3D printer house 100 is, for example, built by assembly on a foundation F, and includes a house main body 110 composed of a plurality of frames 5 described later, a roof 120 also composed of the frame 5, and a plurality of windows M (fittings). The 3D printer house 100 with such a configuration is manufactured through various steps including, for example, a printer output step S1, a painting and waterproofing step S2, a transportation consideration step S3, a transportation step S4, a foundation step S5, a frame assembly step S6, and other component manufacturing steps S7.

[0013] Note that the 3D printer 3 (see Fig. 2. The 3D printers 3-1 to 3-n (n is an integer value of 1 or more) are collectively referred to) has different data formats depending on, for example, the printer manufacturer and the printer type. That is, the forms of the digital data are different. Therefore, the center server 1 described later in Fig. 2 is equipped with a function that enables conversion of the form of digital data according to the 3D printer 3 (output 3D printer) to be used.

[0014] First, the above-mentioned printer output step S1 will be described. Fig. 2 is a diagram for explaining the printer output step in Fig. 1.

[0015] The information processing system related to the manufacture of the 3D printer house 100, specifically the manufacture of the frame 5, can manufacture the frame 5 by controlling the execution of the printer output step S1 with the following flow. First, when the user operates the user terminal 4, order information is input, and this input order information is transmitted from the user terminal 4 to the center server 1. This order information includes the conditions desired by the user, that is, user conditions (specific examples of user conditions will be described later).

[0016] Next, the center server 1 receives the order information transmitted from the user terminal 4. Based on the user conditions included in the order information, the center server 1 determines the judgment elements for determining the 3D printer 3 that manufactures at least a part of the 3D printer house 100. After the determination elements are determined, based on the determined determination elements, the center server 1 extracts one or more candidates suitable for use from among a plurality of pre-registered 3D printers 3 (registered 3D printers).

[0017] Note that when the center server 1 cannot extract a candidate 3D printer 3 (when candidate extraction is not possible), a change request for changing user conditions is generated, and this generated change request is transmitted to the user terminal 4.

[0018] After one or more candidates suitable for use are extracted from among the plurality of 3D printers 3, the center server 1 determines a 3D printer 3 (output 3D printer) to be used for manufacturing the housing 5 from among the one or more extracted candidates. When the 3D printer 3 is determined, the center server 1 converts the 3D housing data (digital data) according to the format of the 3D printer 3 that will be used as a result of the determination. Specifically, the form of the 3D housing data is converted into a form of digital data that can be handled by the 3D printer 3 by a slicer for the 3D printer 3.

[0019] After the conversion into a form that can be handled by the 3D printer 3 (output 3D printer) used for manufacturing the housing 5, the center server 1 transmits the 3D housing data to the print server 2 that manages the 3D printer 3. The print server 2 that manages the 3D printer 3 receives the 3D housing data transmitted from the center server 1.

[0020] After receiving the 3D housing data, the print server 2 that manages the 3D printer 3 (output 3D printer) transmits the 3D housing data to the 3D printer 3 used for manufacturing the housing 5. After receiving the 3D housing data, the 3D printer 3 (output 3D printer) starts manufacturing the housing 5.

[0021] One or more frameworks 5 that make up the 3D printer house 100 are manufactured by the information processing system in the above-described process flow. In the printer output step S1, since one or more frameworks 5 that make up the 3D printer house 100 are manufactured using the 3D printer 3, it is possible to contribute to shortening the construction period and reducing costs.

[0022] According to the information processing system, first, for example, a plurality of 3D printers 3 existing at home and abroad, including those other than the company's own, are registered in advance. Next, if the 3D printer 3 used for manufacturing the framework 5 is determined from among them and the 3D house data is transmitted and received, for example, even if the company does not increase the number of 3D printers it owns (or even if the company does not own a 3D printer 3), it is possible to manufacture many 3D printer houses 100 at various locations according to the user's order. In other words, by adopting the above-described information processing system (in the service provided by adopting the above-described information processing system), for example, even if the company does not increase the number of 3D printers it owns, it is possible to increase the production quantity and spread of the 3D printer house 100 by a method similar to remote operation.

[0023] Next, the configuration of the above-described information processing system will be described with reference to FIG. 3. FIG. 3 is a diagram showing an example of the configuration of an information processing system including the center server of FIG. 2.

[0024] The information processing system shown in FIG. 3 is configured to include a center server 1, a print server 2, a 3D printer 3, and a user terminal 4. The center server 1, the print server 2, and the user terminal 4 are interconnected via a predetermined network N such as the Internet. The 3D printer 3 is directly connected to the corresponding print server 2 (this is an example, and it may be connected via the above-described predetermined network N or another network).

[0025] The center server 1 is an information processing device managed by, for example, an administrator of an information processing system. The center server 1 executes various processes while appropriately communicating with the print server 2 and the user terminal 4.

[0026] The print server 2 is managed by, for example, a printer administrator who has jurisdiction over the 3D printers 3 at various locations, or an administrator of an information processing system, etc. The print server 2 is an information processing device for controlling the 3D printers 3. The print server 2 executes various processes for realizing this service while appropriately communicating with the center server 1 and the 3D printers 3. Here, it is assumed that there are a plurality of print servers 2, and they are denoted by reference numerals 2-1 to 2-n (n is an integer value of 1 or more). When there is no need to distinguish them individually, they will be referred to as the print server 2.

[0027] As described with reference to FIG. 2, the 3D printer 3 forms one layer by outputting a material onto a predetermined surface parallel to the XY plane based on a 3D model prepared in advance for manufacturing the 3D printer housing 100 (for manufacturing one or more housings 5), and then further moves the head in a substantially Z direction (substantially vertical direction) to print the next layer so as to stack it on the said layer (which will be described later with reference to FIG. 8). There is one or more 3D printers 3 for each of the print servers 2-1 to 2-n. For example, for the print server 2-1, they are denoted by reference numerals 3-1-1 to 3-1-m (m is an integer value of 1 or more). Also, for example, for the print server 2-n, they are denoted by reference numerals 3-n-1 to 3-1-p (p is an integer value of 1 or more) (when there is no need to distinguish them individually, they will be referred to as the 3D printer 3 as described above).

[0028] The user terminal 4 is an information processing device managed and operated by a user (not shown). The user terminal 4 is composed of a personal computer, a tablet, a smartphone, etc. Since there are multiple users, there are also multiple user terminals 4 accordingly. Here, they are given symbols 4-1 to 4-k (k is an integer value of 1 or more), and when there is no need to distinguish them individually, they are collectively referred to as user terminal 4.

[0029] Next, with reference to FIG. 4, an example of the hardware configuration of the center server 1 in the information processing system shown in FIG. 3 will be described. FIG. 4 is a block diagram showing an example of the hardware configuration of the center server in the information processing system shown in FIG. 3.

[0030] The center server 1 includes a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a bus 14, an input / output interface 15, an input unit 16, an output unit 17, a storage unit 18, a communication unit 19, and a drive 20.

[0031] The CPU 11 executes various processes according to the programs recorded in the ROM 12 or the programs loaded from the storage unit 18 to the RAM 13. In the RAM 13, data and the like necessary for the CPU 11 to execute various processes are also appropriately stored.

[0032] The CPU 11, ROM 12, and RAM 13 are interconnected via the bus 14. The input / output interface 15 is also connected to this bus 14. The input unit 16, output unit 17, storage unit 18, communication unit 19, and drive 20 are connected to the input / output interface 15.

[0033] The input unit 16 is composed of, for example, a keyboard, a touch panel, etc., and accepts the input of various information. The output unit 17 is composed of a display such as a liquid crystal display and a speaker, etc., and outputs various information as images and sounds. The memory unit 18 is composed of a DRAM (Dynamic Random Access Memory) or the like, and stores various data. The communication unit 19 communicates with other devices (for example, the print server 2 and the user terminal 4 shown in FIG. 2) via a network N including the Internet.

[0034] A removable medium 30 made of a magnetic disk, an optical disk, a magneto-optical disk, or a semiconductor memory or the like is appropriately mounted on the drive 20. The program read from the removable medium 30 by the drive 20 is installed in the memory unit 18 as necessary. Also, the removable medium 30 can store various data stored in the memory unit 18 in the same manner as the memory unit 18.

[0035] Although not shown, the print server 2 and the user terminal 4 in FIG. 3 can also have a configuration basically the same as the hardware configuration shown in FIG. 4. Therefore, the description of the hardware configurations of the print server 2 and the user terminal 4 of the information processing system is omitted.

[0036] Through the cooperation of various hardware and various software that make up the information processing system shown in FIG. 3 including the center server 1 in FIG. 4, the center server 1 can execute various processes.

[0037] Hereinafter, the functional configuration executed in the center server 1 that constitutes the information processing system will be described. FIG. 5 is a functional block diagram showing an example of the functional configuration of the center server in FIG. 4 in the information processing system in FIG. 3.

[0038] As shown in FIG. 5, in the CPU 11 of the center server 1, a printer output control unit 51, a painting waterproof control unit 52, a transportation consideration control unit 53, a transportation control unit 54, a foundation work control unit 55, a building assembly control unit 56, and an other parts manufacturing control unit 57 function. In addition, the storage unit 18 of the center server 1 is provided with an order information DB 71, a 3D printer information DB 72, and a 3D housing data DB 73.

[0039] Based on the above-described 3D housing data, the printer output control unit 51 executes control for manufacturing one or more frameworks 5 that constitute the 3D printer housing 100 using the material output from the header 6-1 (see FIGS. 8 and 9) of the 3D printer 3.

[0040] In executing the control for manufacturing the framework 5, although not particularly shown, the printer output control unit 51 functions as an order information acquisition unit, a determination element determination unit, a candidate extraction unit, a 3D printer determination unit, a digital data transmission control unit, a digital data format conversion unit, and a user condition change request unit.

[0041] The above-described order information acquisition unit in the printer output control unit 51 acquires order information (for example, order information input and ordered on the display screen shown in FIG. 6) for the user to order the manufacture of a building (for example, the 3D printer housing 100 in FIG. 1) from the user terminal 4 of the user. Here, the order information at least includes user conditions desired by the user. The user conditions include a budget, a delivery date, the location where the above-described building is to be arranged (for example, the construction site shown in FIG. 7), and the design of the building. The order information acquired by the order information acquisition unit is stored in the order information DB 71.

[0042] In addition, the order information acquisition unit in the printer output control unit 51 acquires order information including new user conditions as new user conditions specified by the user who has received a change request described later from the user terminal 4. The order information including the above-described new user conditions (described later) is stored, for example, in the order information DB 71.

[0043] The above-mentioned determination element determination unit in the printer output control unit 51 determines a determination element (described later) for determining a 3D printer 3 (output 3D printer) that manufactures at least a part (such as the building body 5, etc.) of the building based on the user conditions included in the order information. Regarding the above-mentioned "manufacturing at least a part (such as the building body 5, etc.)", the place of manufacturing shall refer to the place where the 3D printer 3 is installed.

[0044] The information of the 3D printer 3, that is, various information such as the manufacturer, type, installation location, and operating status, etc., shall be stored in the 3D printer information DB 72 in advance, for example (the 3D printer 3 as the registration information stored in the 3D printer information DB 72 corresponds to the "registered 3D printer" described later). The 3D printer information DB 72 also stores information necessary for transporting the above-mentioned part, etc. manufactured by the 3D printer 3 (output 3D printer) (for example, transportation cost, transportation method, etc.).

[0045] In addition to the above, the determination element determination unit determines, as the above-mentioned determination elements, the budget, the moving distance from the place, the earthquake resistance strength, the delivery date, and the type of the 3D printer 3 capable of constructing the building of the design, etc. based on the budget, delivery date, place where the building is located, and the design of the building included in the user conditions.

[0046] The above-mentioned candidate extraction unit in the printer output control unit 51 extracts one or more from the plurality of the above-mentioned registered 3D printers registered in the 3D printer information DB 72 in advance as candidates based on the above-mentioned determination elements. In addition, the candidate extraction unit redetermines the above-mentioned determination elements based on the new user conditions (described later) included in the order information, and extracts the above-mentioned one or more 3D printers 3 (registered 3D printers) based on the redetermined determination elements.

[0047] The above-mentioned 3D printer determination unit in the printer output control unit 51 determines one of the above-mentioned one or more registered 3D printers extracted as candidates as the output 3D printer (here, it is assumed that one is determined, but this is not limited to this).

[0048] The above-mentioned digital data transmission control unit in the printer output control unit 51 executes control to transmit the digital data to a control device (such as the print server 2 in FIG. 2) that controls the above-mentioned output 3D printer (3D printer 3) based on digital data such as 3D house data. In addition, the digital data transmission control unit executes control to transmit the digital data whose form has been converted by the digital data form conversion unit described later to the above-mentioned control device. Note that digital data such as 3D house data is assumed to be stored in the 3D house data DB 73 in advance, for example.

[0049] The above-mentioned digital data form conversion unit in the printer output control unit 51 converts the form of digital data such as 3D house data into a form that can be handled by the output 3D printer (3D printer 3) using a slicer for the output 3D printer.

[0050] When it is determined that there is no registered 3D printer (3D printer 3) to be extracted as a candidate by the above-mentioned candidate extraction unit, the above-mentioned user condition change request unit in the printer output control unit 51 executes control to transmit a request for changing the above-mentioned user conditions to the user terminal 4.

[0051] Since the above-mentioned order information acquisition unit, determination element determination unit, candidate extraction unit, 3D printer determination unit, and digital data transmission control unit in the printer output control unit 51 each function, it is possible to contribute to shortening the construction period and reducing costs because manufacturing can be performed using the 3D printer 3.

[0052] In this embodiment, by the respective functions of an order information acquisition unit, a determination element determination unit, a candidate extraction unit, a 3D printer determination unit, and a digital data transmission control unit, for example, a plurality of 3D printers 3 existing at home and abroad, including those other than the company's own, are registered in advance, and from among them, a 3D printer 3 used for manufacturing the 3D printer house 5 is determined, and the transmission and reception of 3D house data are performed. For example, even if the company does not increase the number of owned 3D printers (or even if the company does not own a 3D printer 3), a large number of 3D printer houses 100 can be manufactured at various locations according to the user's order.

[0053] Also, in this embodiment, by the function of the above-described digital data form conversion unit, the form of the digital data can be converted into a form that can be handled by the output 3D printer using a slicer for the output 3D printer. Therefore, for example, the 3D printer house 100 can be manufactured regardless of the manufacturer or type of the 3D printer 3. Also, in this embodiment, by the function of the above-described user condition change request unit, when it is determined that there is no registered 3D printer to be extracted as a candidate, control can be executed to transmit a request for changing the user conditions to the user terminal 4. Thereby, the 3D printer house 100 can be manufactured based on the changed order information including new user conditions (described later).

[0054] The painting and waterproofing control unit 52 in the CPU 11 executes control for a painting and waterproofing operation on one or more housings 5 manufactured (or manufactured) under the control of the printer output control unit 51 by a predetermined robot (the painting and waterproofing performed by the predetermined robot will be described later with reference to FIG. 11). Regarding the painting and waterproofing by the predetermined robot, information stored in the order information DB 71, the 3D house data DB 73, etc. is used. By the function of the painting and waterproofing control unit 52, since the predetermined robot performs painting and waterproofing, the involvement of workers in the construction can be reduced, and as a result, it can contribute to shortening the construction period and reducing costs.

[0055] Before transporting one or more hulls 5 manufactured under the control of the printer output control unit 51, the transportation consideration control unit 53 executes control of consideration processing related to reinforcement for ensuring strength capable of withstanding the forces applied during the transportation. In addition, the transportation consideration control unit 53 also executes control of, for example, a processing robot in order to reflect the result of the consideration processing related to the above-described reinforcement on one or more hulls 5. Since the transportation consideration control unit 53 functions, it is possible to ensure strength capable of withstanding the forces applied during transportation, so that, for example, breakage or the like during transportation can be prevented. That is, since there is no need for rework or the like, as a result, it is possible to contribute to shortening the construction period and reducing costs.

[0056] The transportation control unit 54 executes control for transporting one or more hulls 5 for which strength capable of withstanding the forces applied during transportation has been ensured to a predetermined location where the 3D printer house 100 is arranged or the vicinity thereof. In the present embodiment, the transportation control unit 54 executes control of various robots (including a crane or the like) used for packing the hull 5 and loading it onto a predetermined transport vehicle (such as a truck), and control of creating a transport plan by the transport vehicle. Since the transportation control unit 54 functions, it is possible to improve the efficiency during transportation, so that, as a result, it is possible to contribute to shortening the construction period and reducing costs.

[0057] The foundation work control unit 55 executes control for manufacturing at least the formwork FK (see FIGS. 1 and 13) of the foundation F (see FIGS. 1 and 13) for assembling one or more hulls 5. In the present embodiment, the foundation work control unit 55 also executes control for manufacturing (printing) the formwork FK using the 3D printer 3 in the same manner as the hull 5. In addition, at a predetermined location where the 3D printer house 100 is arranged, control of robots for performing foundation work (for example, a robot for placing concrete, a crane, a steel bar binding robot, etc.) is also executed. By the function of the foundation work control unit 55, the foundation work that has been carried out by craftsmen can be robotized, for example, and as a result, it can contribute to shortening the construction period and reducing costs.

[0058] The frame assembly control unit 56 executes control for assembling one or more frames 5 at the above-mentioned predetermined location (the predetermined location where the 3D printer house 100 is arranged). In the present embodiment, the frame assembly control unit 56 executes control of a robot (including a crane, a concrete pump truck, etc.) that assembles one or more frames 5. In addition, when assembling one or more frames 5, the frame assembly control unit 56 also executes control for incorporating the prefabricated interior 220 (see FIG. 15) into the housing main body 210. Regarding the above-mentioned interior 220, the frame assembly control unit 56 includes an interior assembly control unit 561 and executes control for assembling the interior 220. This interior assembly control unit 561 functions when assembling the interior 220, for example, at an interior assembly factory different from the above-mentioned predetermined location (the predetermined location where the 3D printer house 100 is arranged). The assembled interior 220 is transported, for example, under the control of the above-mentioned transport control unit 54. By the function of the frame assembly control unit 56 including the interior assembly control unit 561, the assembly work that has been carried out by craftsmen can be robotized, for example, and as a result, it can contribute to shortening the construction period and reducing costs.

[0059] The other part manufacturing control unit 57 executes control for manufacturing other parts (for example, fittings such as window M) other than one or more frames 5 using another 3D printer 7 (see FIG. 21) different from the 3D printer 3. In the present embodiment, the other part manufacturing control unit 57 controls the above-mentioned other 3D printer 7 to control the manufacturing of the window M and the like. By the function of the other part manufacturing control unit 57, the manufacturing of fittings that has been carried out by craftsmen can be robotized, for example, and as a result, it can contribute to shortening the construction period and reducing costs.

[0060] Here, an example of the process of manufacturing the 3D printer house 100 executed by the above-described center server 1 and the like will be described. Although the illustration of the flowchart is omitted, for convenience of explanation, the following description will be made using the step numbers of steps S11 to S22 (in the following description, it is assumed that there is a description of "not shown" before steps S11 to S22 except for a part shown in FIG. 7).

[0061] In step S11, the user terminal 4 transmits the order information input by the user to the center server 1. After the execution of step S11, the process proceeds to step S12.

[0062] In step S12, the center server 1 receives the order information transmitted from the user terminal 4. At this time, in the center server 1, the order information acquisition unit in the printer output control unit 51 functions. After the execution of step S12, the process proceeds to step S13.

[0063] In step S13, the center server 1 determines the determination elements for determining at least a part (one or more frameworks 5) of the 3D printer house 100 to be manufactured by the 3D printer 3 based on the user conditions included in the order information. At this time, in the center server 1, the determination element determination unit in the printer output control unit 51 functions. After the execution of step S13, the process proceeds to step S14.

[0064] In step S14, the center server 1 extracts one or more candidates suitable for use from among a plurality of pre-registered 3D printers 3 (registered 3D printers) based on the determined determination elements. At this time, in the center server 1, the candidate extraction unit in the printer output control unit 51 functions. After the execution of step S14, the process proceeds to step S15.

[0065] In step S15, the center server 1 determines whether or not one or more candidates suitable for use have been extracted from among a plurality of pre-registered 3D printers 3 (registered 3D printers). This determination is made by the subsequent candidate extraction unit in the printer output control unit 51 functioning. In the center server 1, when the extraction of the candidate 3D printer 3 cannot be performed (''NO'' in step S15), the process proceeds to step S16, and when the extraction can be performed (''YES'' in step S15), the process proceeds to step S17.

[0066] In step S16, since the center server 1 cannot extract the candidate 3D printer 3, it generates a change request for changing the user conditions and transmits this to the user terminal 4. At this time, in the center server 1, the user condition change request unit in the printer output control unit 51 functions. After the execution of step S16, the process proceeds to step S11.

[0067] In step S17, since the center server 1 has been able to extract the candidate 3D printer 3, it determines the 3D printer 3 (output 3D printer) to be used for manufacturing the housing 5 from among the candidate 3D printers 3. At this time, in the center server 1, the 3D printer determination unit in the printer output control unit 51 functions. After the execution of step S17, the process proceeds to step S18.

[0068] In step S18, the center server 1 converts the form of the 3D housing data (digital data) according to the format of the 3D printer 3 that has been determined to be used by the determination of the 3D printer 3 (output 3D printer) into a form of digital data that can be handled by the 3D printer 3 by a slicer for the 3D printer 3. At this time, in the center server 1, the digital data form conversion unit in the printer output control unit 51 functions. After the execution of step S18, the process proceeds to step S19.

[0069] In step S19, the center server 1 transmits 3D house data converted into a form of digital data that can be handled by the 3D printer 3 (output 3D printer) to the print server 2 that has jurisdiction over the 3D printer 3. At this time, in the center server 1, the digital data transmission control unit in the printer output control unit 51 functions. After the execution of step S19, the process proceeds to step S20.

[0070] In step S20, the print server 2 receives the 3D house data transmitted from the center server 1. After the execution of step S20, the process proceeds to step S21.

[0071] In step S21, the print server 2 transmits the 3D house data to the 3D printer 3 (output 3D printer) used for manufacturing one or more building bodies 5. After the execution of step S21, the process proceeds to step S22. In step S22, the 3D printer 3 (output 3D printer) manufactures one or more building bodies 5 that constitute the 3D printer house 100 based on the received 3D house data.

[0072] An example in which order information is input by a display screen displayed on the user terminal 4 will be described with reference to FIG. 6. FIG. 6 is a diagram showing an example in which order information is input by a display screen displayed on a user terminal in the information processing system of FIG. 3.

[0073] On the display screen (user screen YG) of the user terminal 4, for example, a budget input field, an input field for the location where the building is to be placed (for example, the construction site of the 3D printer house 100 shown in FIG. 7), a delivery date input field, a building design selection field, and other input fields are displayed (this is an example and is not limited to these). With this display, the user can input user conditions desired by the user into the above-described various input fields and the above-described selection fields. Then, the user terminal 4 can generate order information including at least user conditions, and can send this to the center server 1. In addition, when there is a request to change the above-mentioned user conditions, the user can input again, and can send order information including at least the new user conditions to the center server 1.

[0074] At the center server 1, based on the "budget" among the user conditions included in the acquired order information, the determination element is also determined to be "budget". Also, based on the "location" among the user conditions, the determination elements are determined to be "moving distance from the construction site" and "seismic resistance strength (material strength, compressive strength)". Also, based on the "delivery date" among the user conditions, the determination element is also determined to be "delivery date". Also, based on the "design" among the user conditions, the determination element is determined to be "3D printer capable of construction". As for these others, the determination element is determined to be "others such as heat insulation and fire resistance".

[0075] Referring to FIG. 7, an example based on the above-mentioned order information will be described. FIG. 7 is a diagram showing an example of the flow in which a building body is manufactured in an example based on the order information input by the display screen of FIG. 6.

[0076] The example in FIG. 7 is an example in which order information CJ-1 in which the user's request is "I want to construct a 3D printer house 100 with design C at a predetermined location in X Prefecture within 1 month with a budget of 3 million yen" is received by the center server 1. At the center server 1, one or more candidates for the 3D printer 3 are extracted based on the order information CJ-1 and the determination elements (for example, steps S14 etc. not shown above).

[0077] The decision-making factors in this case are "transportation distance from the construction site, there is no 3D printer 3 within X Prefecture, so re-presentation of transportation costs (+〇 million yen increase)", "delivery date (operation status of 3D printer)", "seismic-resistant structure, compressive strength of materials, national seismic-resistant standards", etc. Note that the above-mentioned "re-presentation" shows an example when the decision in step S15 above is "NO" and the process proceeds to step S16. In this case, three candidates for 3D printer 3 can be extracted. The first candidate, KP-1, is a 3D printer 3 in X Prefecture, and its operation status is such that the delivery date is subject to a two-month wait. The second candidate, KP-2, is also a 3D printer 3 in X Prefecture, and its operation status is such that the delivery date is subject to a one-month wait. The third candidate, KP-3, is a 3D printer 3 not in X Prefecture but in Y Prefecture, and its operation status is such that the delivery date is subject to a one-week wait.

[0078] In the center server 1, for example, if delivery date is emphasized among the three candidates KP-1 to KP-3, the 3D printer 3 of candidate KP-3 is determined as the output 3D printer (for example, in step S17 etc. mentioned above). Also, in the center server 1, after the 3D printer 3 of candidate KP-3 is determined as the output 3D printer, the form of the 3D house data (digital data) of design C is converted into a form of digital data that can be handled by the 3D printer 3 by the slicer for the 3D printer 3 (for example, in step S18 etc. mentioned above). The converted 3D house data of design C is transmitted from the center server 1 to the print server 2 that has jurisdiction over the 3D printer 3 (output 3D printer) and is received (for example, in steps S19 and S20 etc. mentioned above).

[0079] Note that the above example is for Japan, but it can also be applied to foreign countries. In that case, X Prefecture above can be read as X Country, and Y Prefecture can be read as Y Country.

[0080] With reference to Figure 8, the manufacturing (printing) of the building body 5 using the 3D printer 3 will be described. FIG. 8 is a diagram showing an example of manufacturing (printing) a housing using a 3D printer in the printer output step of FIG. 1.

[0081] In a factory (not shown), a 3D printer 3 for performing additive manufacturing by printing is arranged. The 3D printer 3 can store a material such as concrete, mortar, or ceramic in a storage unit by passing it through, for example, two hoses, and then output (discharge) it from a header 6-1 (denoted as 6 if there is no need to distinguish). Based on 3D housing data, the 3D printer 3 forms one layer by outputting a material onto a predetermined surface parallel to the XY plane, and then further moves the header 6-1 in a substantially Z direction (substantially vertical direction) to print the next layer so as to stack it on the said layer. The 3D printer 3 can print a wall-like housing 5 of the 3D printer housing 100, for example, as shown in FIG. 8, by stacking a plurality of layers in a substantially Z direction (substantially vertical direction).

[0082] The wall-like housing 5 shown in FIG. 8 has two surfaces, namely, a surface that becomes an outer wall and a surface that becomes an inner wall. The wall-like housing 5 also has ribs R1 to R4 that are substantially perpendicular to the two surfaces. Although not particularly limited, in this embodiment, a method of forming a double structure with two surfaces (hereinafter referred to as the "double structure method") is adopted. If the double structure method is adopted, for example, by inserting a heat insulating material or the like between the two surfaces, the heat insulating effect can be enhanced, and the sound insulating effect and the like can also be enhanced.

[0083] The above-mentioned wall-like housing 5 has openings H1 and H2. The openings H1 and H2 are formed as, for example, frame-like portions for providing reinforcing bars or concrete columns (or formed as structural portions for injecting a special mortar that substitutes for reinforcing bars or concrete (effective as a portion that meets building standards)).

[0084] In FIG. 8, a wall-shaped housing 5 is manufactured (printed) by stacking a plurality of layers in the Z direction (substantially vertical direction). However, the 3D printer 3 of the present embodiment can also manufacture a housing 5 that requires an angle (overhang) as shown in FIG. 9, for example.

[0085] Referring to FIG. 9, a first example of manufacturing (printing) a housing 5 that requires an angle (overhang) will be described. FIG. 9 is a diagram showing an example (first example) of manufacturing (printing) a housing (for example, a roof) with an angle in the printer output step of FIG. 1.

[0086] For the 3D printer 3 shown in FIG. 9, for example, a curing accelerator for promoting the curing of the material is mixed in the head 6-1, and the material after mixing the curing accelerator is output from the head 6-1 and cured in, for example, 30 seconds. Also, if the 3D printer 3 is controlled to shift the stacking of the materials, a housing 5 (for example, a dome-shaped roof) that requires the angle (overhang) shown in FIG. 9 can be manufactured (printed). In FIG. 9, by controlling the 3D printer 3 so as to shift the stacking of the material mixed with the curing accelerator, a housing 5 that requires an angle (overhang) of, for example, 45 degrees or more, such as a roof, can be easily and quickly manufactured. Therefore, it can contribute to shortening the construction period and reducing costs.

[0087] Referring to FIG. 10, a second example of manufacturing (printing) a housing 5 that requires an angle (overhang) will be described. FIG. 10 is a diagram showing an example (second example) of manufacturing (printing) a housing (for example, a roof) with an angle in the printer output step of FIG. 1.

[0088] The 3D printer house 150 shown in FIG. 10(a) has a wall / roof integrated housing 5 that is substantially in a V shape. This wall / roof integrated housing 5 is arranged such that the portion indicated by reference numeral 5a is on the lower side, the portion indicated by reference numeral 5b is on the upper side, and the portion indicated by reference numeral 5c is on the front side in FIG. 10(a). Although the body 5 requires an angle (overhang), by controlling the 3D printer 3 to stack materials in the direction of the arrow as shown in Fig. 10(b), a wall / roof integrated body 5 in a "lying horizontally" state can be easily and quickly manufactured. Therefore, it can contribute to shortening the construction period and reducing costs.

[0089] In the second example, after manufacturing the wall / roof integrated body 5 in a "lying horizontally" state, by changing it to the state shown in Fig. 10(a), that is, an upright state, even a body 5 that requires an angle (overhang) can of course be easily manufactured. In addition, since the horizontal stripe stacking marks shown in Fig. 10(b) cause the body 5 to become vertical, for example, it is possible to facilitate the flow of rainwater and the like, and it is also possible to make it difficult for dirt to adhere.

[0090] Next, with reference to Fig. 11, the above-mentioned painting and waterproofing step S2 will be described. Fig. 11 is a diagram showing the painting and waterproofing step of Fig. 1. (a) is a diagram showing the head of a 3D printer equipped with a nozzle for material output and a nozzle for painting. (b) is a diagram showing the material mixed with paint. (c) is a diagram showing dipping the manufactured body into a paint pool.

[0091] The head 6-1 shown in Fig. 11(a) is configured with a nozzle for material output and a nozzle for painting (or is configured with a nozzle for material output, a nozzle for painting, and a nozzle for spraying waterproof paint (not shown)). By adopting such a head 6-1, painting and waterproofing can be performed simultaneously with the manufacture (printing) of the body 5. As a result, it can contribute to shortening the construction period and reducing costs.

[0092] The pump for material supply shown in Fig. 11(b) is filled with a material in which, for example, solid paint for the 3D printer 3 is mixed. By using such a material, painting can be performed simultaneously with the manufacture (printing) of the body 5. As a result, the painting process can be labor-saving. In other words, it can contribute to shortening the construction period and reducing costs. As shown in FIG. 11(c), the manufactured housing body 5 may be lifted by a crane and immersed in a paint-filled pool tank, whereby painting may be performed all at once.

[0093] Subsequently, with reference to FIG. 12, the above-described transportation study step S3 and transportation step S4 will be described. FIG. 12 is a diagram showing the transportation study step and transportation step of FIG. 1. (a) is a diagram showing the transportation study state, and (b) is a diagram showing the transportation state based on the transportation study result.

[0094] In the transportation study step S3, as shown in FIG. 12(a), the situation of the housing body 5 during transportation (for example, the stress distribution by stress analysis, etc.) is visualized. Whether the housing body 5 is damaged during transportation is examined by the center server 1, and reinforcement or the like based on the examination is applied to the housing body 5. Examples of reinforcement include injecting special mortar or the like into the openings H1 and H2 (see FIG. 8) of the housing body 5 described above (this is to be taken as an example). Note that before the manufacture of the housing body 5, a study is conducted (in this case, the transportation study step S3 is performed before the printer output step S1 or at the same timing, etc.). Based on the study result, for example, reinforcing bars or the like are inserted into the portions that require reinforcement, or injection of special mortar or the like as described above is performed.

[0095] In the transportation step S4, as shown in FIG. 12(b), the housing body 5 is lifted by the crane C and loaded onto the truck T. The truck T transports the housing body 5 to a predetermined location where the 3D printer house 100 is located or the vicinity thereof based on the transportation plan created by the center server 1. Note that since the 3D printer 3 is away from the above-described predetermined location (construction site), the transportation study step S3 and transportation step S4 are executed. However, this is not the case when the 3D printer 3 is installed at the predetermined location.

[0096] Next, with reference to FIG. 13, the above-described basic step S5 and the body assembly step S6 will be described. FIG. 13 is a diagram showing the basic step and the body assembly step of FIG. 1.

[0097] Steps ST1 and ST2 shown in FIG. 13 correspond to the basic step S5 of FIG. 1. Also, steps ST3 and ST4 shown in FIG. 13 correspond to the body assembly step S6 of FIG. 1.

[0098] First, in step ST1, at a predetermined location (construction site, site) where the 3D printer house 100 is to be placed, a formwork FK for the foundation F, reinforcing bars TK provided inside thereof, and column foundation reinforcing bars TP1 to TP4 are arranged. The column foundation reinforcing bars TP1 to TP4 are installed to be longer (higher) by a predetermined length than the height of the foundation F. Next, in step ST2, concrete is placed inside the formwork FK of the foundation F. As a result, a solid foundation is formed, and the column foundation reinforcing bars TP1 to TP4 protrude above the foundation F.

[0099] Note that the formwork FK corresponds to a plurality of bodies 5 manufactured (printed) by the 3D printer 3. By manufacturing (printing) the formwork FK by the 3D printer 3, it is possible to be speedy and reduce the involvement of craftsmen in the foundation work, and as a result, it is possible to contribute to shortening the construction period and reducing costs. Regarding the reinforcing bars TK, in this embodiment, a reinforcing bar binding robot is used. Regarding the placement of concrete, the hardening time can be shortened by using a hardening accelerator or quick-drying concrete. Incidentally, normal foundation work (foundation work for general buildings) was carried out by craftsmen and took several days. After that, it also took several weeks for curing.

[0100] Next, in step ST3, one or more bodies 5 manufactured (printed) by the 3D printer 3 are installed on the foundation F using a crane C.

[0101] Next, in step ST4, the assembly of one or more bodies 5 proceeds, and for example, concrete is poured into the openings H1 to H4 from the hose HO of the concrete pump truck CP, respectively. Although not shown in FIG. 13, the assembly of one or more bodies 5 can proceed while incorporating the prefabricated interior 220 (see FIG. 15). Also, for example, the assembly of the roof 120 (body 5) as shown in FIG. 1 can proceed.

[0102] Subsequently, with reference to FIG. 14, the manufacturing of the body 5e in which the part of the foundation 5e-2 is integrated will be described. FIG. 14 is a diagram showing a body in which the foundation part is integrated, (a) is a diagram showing a cross-section of the body, and (b) is a diagram showing an example of the manufacturing of the body in (a).

[0103] In FIG. 14, the 3D printer house 180 includes bodies 5e, 5f, and 5g manufactured (printed) by the 3D printer 3, and the assembly is completed by joining them as shown in the figure. The body 5e and the body 5f are manufactured in a shape in which the foundation 5e-2 is integrated with the wall 5e-1. Also, the body 5g is manufactured in a shape that functions as a roof. Taking the body 5e as an example, similar to the second example described above, the wall 5e-1 and the foundation 5e-2 are manufactured in a "lying horizontally state", and by raising this vertically, it is arranged in the state shown in (a) of FIG. 14. Note that the bodies 5f and 5g are also manufactured in a "lying horizontally state" like the body 5e. Since the 3D printer house 180 has the shape as described above, the foundation work can be greatly simplified, and as a result, it can contribute to shortening the construction period and reducing costs.

[0104] Subsequently, with reference to FIG. 15, the step of assembling the body 210 by incorporating the interior 220 will be described. FIG. 15 is a diagram showing the body assembly step of FIG. 1. (a) is a diagram showing an example of the exterior of a building, and (b) is a diagram showing an example of the step of assembling the body while incorporating the interior of the building in (a).

[0105] In FIG. 15(a), the 3D printer house 200 includes a body 210 that constitutes walls, a roof, etc., and an interior 220 incorporated inside the body 210. The body 210 is manufactured (printed) by the 3D printer 3. The interior 220 is manufactured in a predetermined factory in advance and transported to a predetermined location (construction site, site) in the above-described transportation step S4.

[0106] Subsequently, the interior 220 of FIG. 15 will be described with reference to FIGS. 16 and 17 respectively. FIG. 16 is a diagram showing the interior of FIG. 15. (a) is a diagram showing an example (first example) of the manufacture of an interior box that constitutes the interior, and (b) is a diagram showing an example of interior furniture, etc. in the interior box incorporated when assembling the body. FIG. 17 is a diagram showing an example (second example) of an interior box that constitutes the interior of FIG. 15.

[0107] The interior 220 is manufactured using a plurality of robotic arms as shown in FIG. 16(a) on the line of the above-described predetermined factory. Here, for example, it is manufactured to be an interior box in the shape of a box, and interior furniture, etc. as shown in FIG. 16(b) is arranged inside it. The interior box shown in FIG. 16(a) is an example, and it may be an interior box as shown in FIG. 17 that can be taken in and out of the interior 220, for example. The interior box shown in FIG. 17 is manufactured, for example, to be equipped with a life line for water supply and drainage and the electrical system. Also, such an interior box may be manufactured in the form of a self-propelled vehicle type. By assembling the body 210 while incorporating the interior 220 of FIGS. 15 to 17, it is possible to contribute to shortening the construction period and reducing costs as compared with the case of performing interior work later.

[0108] Next, with reference to FIG. 18, the assembly of the roof 120 and the like will be described. FIG. 18 is a diagram showing the steps of assembling the housing body in FIG. 1. (a) is a diagram showing an example of assembling the housing body (roof), and (b) is a diagram showing an example of a roof having a shape different from that in (a).

[0109] The roof 120 manufactured (printed) by the 3D printer 3 is lifted by the crane C and assembled to the housing main body 110 as shown in FIG. 18(a). Manufacturing the roof 120 by the 3D printer 3 and assembling it at the above-mentioned predetermined location (construction site) can contribute to shortening the construction period and reducing costs. Incidentally, ordinary roof work (roof work of general buildings) is carried out by craftsmen and takes about one week.

[0110] FIG. 18(b) shows a roof 300 having a shape different from that of the above-mentioned roof 120. Although not particularly shown, the roof 300 is manufactured in a "lying horizontally state" such as in FIG. 10(b) or FIG. 14(b). The roof 300 is formed in a shape capable of ensuring sufficient strength and has good design.

[0111] Subsequently, with reference to FIG. 19, a roof 430 having a shape different from that of the roof 300 in FIG. 18 will be described. FIG. 19 is a diagram showing an example of a shape different from that of the roof in FIG. 18.

[0112] In FIG. 19, the 3D printer house 400 includes walls 410 and 420 and a roof 430 integrated with these walls 410 and 420. The housing body in which the walls 410 and 420 and the roof 430 are integrated is manufactured in a "lying horizontally state" such as in FIG. 10(b) or FIG. 14(b). Since the walls 410 and 420 and the roof 430 are integrated, there is no need for assembly at the above-mentioned predetermined location (construction site). As a result, it can contribute to shortening the construction period and reducing costs.

[0113] Next, while referring to FIG. 20, the roof 500 different from the roof 300 in FIG. 18 will be described. FIG. 20 is a diagram showing an example of a thing crystallized with glaze, different from the roof in FIG. 18.

[0114] The roof 500 manufactured (printed) by the 3D printer 3 has at least its outer surface crystallized with glaze. Since such a roof 500 is crystallized with glaze, sufficient waterproofness can be ensured, for example, as compared with the outer surface of mortar.

[0115] Next, while referring to FIG. 21, the above-described other part manufacturing step S7 will be described. FIG. 21 is a diagram showing the other part manufacturing steps in FIG. 1. (a) is a diagram showing an example of the appearance of a building, and (b) is a diagram showing an example of a state of manufacturing fittings with a 3D printer.

[0116] In FIG. 21(a), the 3D printer house 600 includes windows M and doors (not shown) as fittings. For example, the window M is manufactured using another 3D printer 7 shown in FIG. 21(b). Specifically, a window frame MW is formed by the other 3D printer 7 at the edge portion of glass having a predetermined shape (here, a triangle), and the manufacturing of the window M shown in FIG. 21(b) is completed. Since the manufacturing of fittings that has been performed by craftsmen can be robotized, for example, as a result, it can contribute to shortening the construction period and reducing costs.

[0117] As described above, one embodiment of the present invention has been described. However, the present invention is not limited to the above-described embodiment, and modifications, improvements, etc. within the range that can achieve the object of the present invention are included in the present invention. In the above-described embodiment, the printing target of the 3D printer 3 is the 3D printer house 100 (frame 5), but it is not particularly limited to this, and any building will do.

[0118] In addition, in the above-described embodiment, the plurality of 3D printers 3 are under the jurisdiction of the print server 2, but it should not be particularly limited thereto.

[0119] In addition, in the above-described embodiment, one 3D printer 3 is determined as the output 3D printer, but it is not particularly limited thereto. For example, the 3D printer 3 in Prefecture X and the 3D printer 3 in Prefecture Y may be determined as the output 3D printers, and the 3D printer house 100 (frame 5) may be manufactured by division of labor. In addition, in the above-described embodiment, for example, the 3D printer house 100 is manufactured in Prefecture X, but it is not particularly limited thereto. For example, a plurality of 3D printer houses 100 may be manufactured simultaneously in a plurality of countries or a plurality of regions within a country.

[0120] In addition, the system configuration shown in FIG. 3 and the hardware configuration of each device of the center server 1 shown in FIG. 4 are merely examples for achieving the object of the present invention and are not particularly limited.

[0121] In addition, the functional block diagram shown in FIG. 5 is merely an example and is not particularly limited. That is, it is sufficient that the information processing system in FIG. 3 is provided with a function capable of executing the above-described various processes as a whole, and the functional blocks and databases used for realizing this function are not particularly limited to the example in FIG. 5.

[0122] In addition, the locations of the functional blocks, models, and databases are not limited to FIG. 5 and may be arbitrary. For example, at least a part of the functional blocks, models, or databases arranged on the center server 1 side may be provided in the print server 2, the user terminal 4, or another information processing device (not shown).

[0123] In addition, the above-described series of processes can be executed by hardware or by software. In addition, one functional block may be configured by hardware alone, by software alone, or by a combination thereof.

[0124] When a series of processes are to be executed by software, the programs constituting the software are installed in a computer or the like from a network or a recording medium. The computer may be a computer incorporated in dedicated hardware. Also, the computer may be a computer capable of executing various functions by installing various programs, such as a general-purpose smartphone or personal computer in addition to a server.

[0125] A recording medium containing such a program is not only constituted by a removable medium (not shown) distributed separately from the apparatus main body to provide the program to the user, but also constituted by a recording medium or the like provided to the user in a state pre-installed in the apparatus main body.

[0126] Note that in this specification, the steps of describing the program recorded on the recording medium include not only the processes performed in time series along the order, but also the processes executed in parallel or individually even if they are not necessarily processed in time series.

[0127] Summarizing the above, the method for manufacturing a building to which the present invention is applied only needs to have the following configuration and can take various embodiments.

[0128] That is, the method for manufacturing a building to which the present invention is applied (for example, the manufacturing method by the printer output step S1 to other partial manufacturing steps S7 in FIG. 1) is A method for manufacturing a building including at least one building body (such as the building body 5 in FIG. 2) manufactured from a material (such as the above-described concrete, mortar, or ceramic material) output from a head (such as the head 6 in FIG. 8) of a 3D printer (such as the 3D printer 3 in FIG. 2) until the building (such as the 3D printer house 100 in FIG. 1) is placed at a predetermined location (for example, the construction site, the site where the 3D printer house 100 is placed, etc.). A printer output step (such as the printer output step S1 in FIG. 1, etc.) of manufacturing the one or more building frames using the material output from the header of the 3D printer based on the digital data of the building (such as the above-mentioned 3D house data, etc.); A frame assembly step (such as the frame assembly step S6 in FIG. 1, etc.) of assembling the one or more frames manufactured in the printer output step at the predetermined location; including: The frame assembly step includes a step of assembling the one or more frames while incorporating the interior decoration of the building (such as the interior decoration 220 in FIG. 15, etc.) manufactured in advance. This is sufficient.

[0129] Thereby, it is possible to shorten the construction period and reduce costs.
