[0023] A. First implementation method:

[0024] Figure 1This is an explanatory diagram showing the general structure of the three-dimensional modeling system 10 in the first embodiment. The three-dimensional modeling system 10 includes a plurality of three-dimensional modeling devices 100 and a control device 400 that communicates with these three-dimensional modeling devices 100. The control device 400 and the plurality of three-dimensional modeling devices 100 can communicate with each other via a predetermined communication line such as the Internet or a LAN (Local Area Network). The three-dimensional modeling system 10 is installed, for example, in a factory, research institute, or commercial facility. In this embodiment, the plurality of three-dimensional modeling devices 100 and the control device 400 are installed in the same location. Alternatively, the three-dimensional modeling devices 100 and the control device 400 may be installed in separate locations instead of in the same location.

[0025] Figure 2 This is an explanatory diagram showing the general structure of the three-dimensional modeling device 100. Figure 2 The diagram shows arrows indicating mutually orthogonal X, Y, and Z directions. The X and Y directions are parallel to the horizontal plane, and the Z direction is vertically upward. These arrows representing the X, Y, and Z directions are also shown in the illustrated directions in other diagrams. Figure 2 The corresponding methods are illustrated appropriately. In the following explanation, when the direction is determined, the direction indicated by the arrow in each diagram will be marked as "+", and the opposite direction will be marked as "-". Both positive and negative signs are used in the direction markings. Hereinafter, the +Z direction will also be referred to as "up", and the -Z direction will also be referred to as "down".

[0026] The three-dimensional modeling apparatus 100 of this embodiment is an apparatus for modeling an object by material extrusion. The three-dimensional modeling apparatus 100 includes a control unit 300 for controlling various parts of the three-dimensional modeling apparatus 100. The control unit 300 and the control device 400 are connected in a manner that allows them to communicate with each other.

[0027] The three-dimensional modeling device 100 includes a modeling section 110 that generates and sprays modeling material, a modeling platform 210 that serves as the base for the modeled object, and a moving mechanism 230 that controls the spraying position of the modeling material.

[0028] Under the control of the control unit 300, the shaping unit 110 sprays the shaping material, which is formed by plasticizing solid material, onto the stage 210. The shaping unit 110 includes a material supply unit 20, which supplies raw materials before they are converted into shaping material; a plasticizing unit 30, which converts raw materials into shaping material; and an ejection unit 60, which sprays out the shaping material.

[0029] The material supply unit 20 supplies raw material MR to the plasticizing unit 30. The material supply unit 20 is, for example, composed of a hopper for storing the raw material MR. The material supply unit 20 is connected to the plasticizing unit 30 via a connecting channel 22. The raw material MR is fed into the material supply unit 20 in the form of granules or powder. As the raw material, for example, resin materials such as ABS (acrylonitrile-butadiene-styrene copolymer), PEEK (polyetheretherketone), and PP (polypropylene) are used.

[0030] The plasticizing section 30 plasticizes the raw material MR supplied from the material supply section 20 to generate a fluid, slurry-like molding material, which is then guided to the ejection section 60. In this embodiment, "plasticizing" refers to a process that includes melting and changes from a solid state to a fluid state. Specifically, in the case of a material undergoing a glass transition, plasticizing means setting the material temperature above the glass transition point. In the case of a material that does not undergo a glass transition, plasticizing means setting the material temperature above the melting point.

[0031] The plasticizing section 30 includes a screw housing 31, a drive motor 32, a flat screw 40, and a barrel 50. The flat screw 40 is also referred to as a rotor or volute. The barrel 50 is also referred to as the screw-opposite section.

[0032] Figure 3 This is a perspective view showing the outline structure of the lower surface 48 side of the flat screw 40. For ease of understanding of the technology, Figure 3 The flat screw 40 shown makes it so that Figure 2 The positional relationship between the upper surface 47 and the lower surface 48 is shown in a state where they are reversed in the vertical direction. Figure 4 This is a schematic top view showing the upper surface 52 side of the material barrel 50. The flat screw 40 has a generally cylindrical shape with a length along its central axis (i.e., the axial direction) less than its length in the direction perpendicular to the axial direction. The flat screw 40 is configured such that its rotation axis RX, which is its center of rotation, is parallel to the Z direction.

[0033] like Figure 2 As shown, the flat screw 40 is housed within the screw housing 31. The upper surface 47 of the flat screw 40 is connected to the drive motor 32, and the flat screw 40 rotates within the screw housing 31 by the rotational driving force generated by the drive motor 32. The drive motor 32 is driven under the control of the control unit 300. Alternatively, the flat screw 40 can also be driven by the drive motor 32 via a reducer.

[0034] like Figure 3As shown, a vortex-shaped groove 42 is formed on the lower surface 48 of the flat screw 40, which is the surface intersecting the rotation axis RX. The communication channel 22 of the material supply section 20 communicates with this groove 42 from the side of the flat screw 40. In this embodiment, the groove 42 is separated by a raised section 43, and three grooves are formed. In addition, the number of grooves 42 is not limited to three; there may be one or more. The groove 42 is not limited to a vortex shape; it may be spiral, involute, or extend in an arc from the center outwards.

[0035] The lower surface 48 of the flat screw 40 faces the upper surface 52 of the material container 50, forming a space between the groove 42 of the lower surface 48 of the flat screw 40 and the upper surface 52 of the material container 50. Within this space between the flat screw 40 and the material container 50, material flows from the material supply section 20... Figure 3 The material inlet 44 shown is used to supply raw material MR.

[0036] like Figure 2 As shown, a drum heater 58 is built into the drum 50 to heat the raw material MR supplied to the slot 42 of the rotating flat screw 40. A connecting hole 56 is provided at the center of the drum 50. Figure 4 As shown, a plurality of guide grooves 54 are formed on the upper surface 52 of the material barrel 50, which are connected to the connecting hole 56 and extend outward in a spiral shape from the connecting hole 56. Alternatively, one end of the guide groove 54 may not be connected to the connecting hole 56. Furthermore, the guide groove 54 may be omitted.

[0037] The raw material MR supplied to the groove 42 of the flat screw 40 is plasticized within the groove 42 and flows along the groove 42 due to the rotation of the flat screw 40, and is guided as a molding material to the central portion 46 of the flat screw 40. The flowing, slurry-like molding material flowing into the central portion 46 is supplied to the ejection portion 60 through the connecting hole 56 provided at the center of the material tank 50. Furthermore, the molding material may not consist of all types of substances constituting the molding material being plasticized. The molding material only needs to be transformed into a fluid state by plasticizing at least some of the substances constituting the molding material.

[0038] Figure 2 The ejection section 60 includes a nozzle 61 for ejecting molding material, a flow channel 65 for molding material disposed between the flat screw 40 and the nozzle opening 62, and an ejection control section 77 for controlling the ejection of molding material.

[0039] Nozzle 61 is connected to the communication hole 56 of material tank 50 through flow channel 65. Nozzle 61 sprays the molding material generated in plasticizing section 30 from nozzle opening 62 at the top toward stage 210.

[0040] The ejection control unit 77 includes an ejection adjustment unit 70 that opens and closes the flow channel 65 and a suction unit 75 that draws in and temporarily stores the molding material.

[0041] An ejection adjustment unit 70 is disposed within a flow channel 65, and the opening degree of the flow channel 65 is changed by rotating within the flow channel 65. In this embodiment, the ejection adjustment unit 70 is configured as a butterfly valve. The ejection adjustment unit 70 is driven by a first drive unit 74 under the control of the control unit 300. The first drive unit 74 is, for example, configured as a stepper motor. The control unit 300 can control the rotation angle of the butterfly valve by using the first drive unit 74, thereby adjusting the flow rate of the molding material flowing from the plasticizing section 30 to the nozzle 61, i.e., the amount of molding material ejected from the nozzle 61. The ejection adjustment unit 70 can adjust the amount of molding material ejected and can control the opening or closing of the flow of molding material.

[0042] A suction unit 75 is connected to the ejection adjustment unit 70 and the nozzle opening 62 on the flow channel 65. When the molding material stops being ejected from the nozzle 61, the suction unit 75 temporarily suctions the molding material from the flow channel 65, thereby suppressing the trailing phenomenon of the molding material drooping from the nozzle opening 62 like a drawn wire. In this embodiment, the suction unit 75 is composed of a plunger. The suction unit 75 is driven by a second drive unit 76 under the control of the control unit 300. The second drive unit 76 is, for example, composed of a stepper motor, a rack and pinion mechanism that converts the rotational force of the stepper motor into the translational motion of the plunger, etc.

[0043] The stage 210 is positioned opposite the nozzle opening 62 of the nozzle 61. In the first embodiment, the shaping surface 211 of the stage 210 opposite the nozzle opening 62 of the nozzle 61 is arranged parallel to the X and Y directions, i.e., the horizontal direction. A stage heater 212 is provided in the stage 210 to suppress the rapid cooling of the shaping material ejected onto the stage 210. The stage heater 212 is controlled by the control unit 300.

[0044] The moving mechanism 230, under the control of the control unit 300, changes the relative position between the stage 210 and the nozzle 61. In this embodiment, the position of the nozzle 61 is fixed, and the moving mechanism 230 moves the stage 210. The moving mechanism 230 is composed of a three-axis positioner that moves the stage 210 in the X, Y, and Z directions by the driving force of three motors. In this specification, unless otherwise specified, the movement of the nozzle 61 refers to the relative movement of the nozzle 61 and the ejection portion 60 relative to the stage 210.

[0045] Alternatively, in other embodiments, instead of moving the stage 210 via the moving mechanism 230, a structure can be adopted in which the moving mechanism 230 moves the nozzle 61 relative to the stage 210 while the stage 210 is in a fixed position. Furthermore, a structure can be adopted where the moving mechanism 230 moves the stage 210 in the Z direction and the nozzle 61 in the X and Y directions, or where the moving mechanism 230 moves the stage 210 in the X and Y directions and the nozzle 61 in the Z direction. These structures also allow for changes in the relative positional relationship between the nozzle 61 and the stage 210.

[0046] The control unit 300 is a device for controlling the overall movement of the three-dimensional modeling device 100. The control unit 300 is composed of a computer, which includes one or more processors 310, a storage unit 320 consisting of a main storage device and an auxiliary storage device, and an input / output interface for inputting and outputting signals to the outside. The processor 310 executes programs stored in the storage unit 320 and controls the modeling unit 110 and the moving mechanism 230 according to the modeling data stored in the storage unit 320, thereby performing modeling on the stage 210. Alternatively, the control unit 300 can be implemented instead of a computer by combining circuits.

[0047] Figure 5 This diagram schematically illustrates the process of the three-dimensional modeling apparatus 100 modeling an object. In the three-dimensional modeling apparatus 100, as described above, a solid raw material MR is plasticized to generate a modeling material MM. While maintaining the distance between the modeling surface 211 of the stage 210 and the nozzle 61, the control unit 300 changes the position of the nozzle 61 relative to the stage 210 along the direction of the modeling surface 211 of the stage 210, and simultaneously ejects the modeling material MM from the nozzle 61. The modeling material MM ejected from the nozzle 61 continuously accumulates in the direction of movement of the nozzle 61.

[0048] The control unit 300 repeatedly moves the nozzle 61 to form a layer ML. After forming a layer ML, the control unit 300 moves the nozzle 61 relative to the stage 210 in the Z direction. Furthermore, the layers ML formed so far are stacked on top of each other to shape the object.

[0049] For example, when the nozzle 61 moves in the Z direction after one layer of material ML has been completed, or when there are multiple independent shaping areas in each layer, the control unit 300 may temporarily interrupt the ejection of shaping material from the nozzle 61. In this case, the flow channel 65 is closed by the ejection adjustment unit 70, thereby stopping the ejection of shaping material MM from the nozzle opening 62, and the shaping material in the nozzle 61 is temporarily sucked in by the suction unit 75. After changing the position of the nozzle 61, the control unit 300 opens the flow channel 65 by the ejection adjustment unit 70 while discharging the shaping material in the suction unit 75, thereby restarting the accumulation of shaping material MM from the changed position of the nozzle 61.

[0050] Figure 6 This is an explanatory diagram showing the general structure of the control device 400. The control device 400 is configured as a computer, wherein a CPU 410, a memory 420, a storage device 430, a communication interface 440, and an input / output interface 450 are interconnected via a bus 460. Input devices such as a keyboard and mouse 470, and a display unit 480 such as a liquid crystal display are connected to the input / output interface 450. The control device 400 is connected to the control unit 300 of the 3D modeling device 100 via the communication interface 440. The control unit 300 sends, for example, information indicating the remaining amount of material fed into the material supply unit 20 of the 3D modeling device 100, and information indicating the progress of the model during modeling, to the control device 400. The control device 400 also sends, for example, modeling data in the control device 400 in which the modeling time has been adjusted.

[0051] CPU 410 functions as display control unit 411 and schedule adjustment unit 412 by executing programs stored in storage device 430. Display control unit 411 displays the styling schedules of each 3D modeling device 100 on display unit 480. Schedule adjustment unit 412 adjusts the operation information described later and adjusts the styling end time of each 3D modeling device 100.

[0052] Figure 7 This diagram illustrates an example of a display screen shown on the display unit 480 via the display control unit 411. The display control unit 411 displays time information D1, operation information D2, and remaining quantity information D3 on the display unit 480. Time information D1 indicates the time. Operation information D2 includes information indicating the modeling time of each model in the respective three-dimensional modeling device 100. The modeling time includes the modeling start time and the modeling end time. In this embodiment, the modeling end time refers to the time when the model has finished cooling after modeling. Figure 7In the example shown as operation information D2, the time required for each 3D modeling device 100 to model in a strip format is displayed, and the name of the model is displayed within the strip. One operation information D2 corresponds to one printing task in that 3D modeling device 100. The remaining amount information D3 indicates the remaining amount of material being used in the selected 3D modeling device 100 among the multiple 3D modeling devices 100. The user can select any 3D modeling device 100 from the list of 3D modeling devices 100 displayed on the left side of the display screen using the input device 470. In addition, although in this embodiment, as described above, the modeling end time is the time when the model has finished cooling, the modeling end time can also be the time when the modeling is completed.

[0053] The display control unit 411 displays the operation information D2 in a manner corresponding to the time information D1. That is, the display control unit 411 displays the time information D1 and the operation information D2 side-by-side along a common time axis. The user can scroll the time information D1 and the operation information D2 along the left-right direction of the display screen using the input device 470. Furthermore, in Figure 7 The displayed screen allows users to specify the time zone and scale of the time information. Users can specify the time zone and scale using an input device. A time zone refers to the entire region that uses a common standard time. The scale of the time refers to the scale of the time axis on the screen. When a time zone has been specified, the display control unit 411 displays the time information D1 according to the specified time zone. Furthermore, when the scale of the time is changed, the display control unit 411 zooms in or out on the length of the time information D1 and the operation information D2 along the time axis. Either the time zone or the scale can also be specified. Additionally, the time zone and scale can be configured by... Figure 7 The different display screens shown can be set separately.

[0054] In this embodiment, the display control unit 411 also displays model information D4, progress information D5, and user information D6 on the display unit 480. Model information D4 refers to information indicating the shape of the model corresponding to the operation information D2. Progress information D5 refers to information indicating the progress of the model being modeled in the selected 3D modeling device 100. User information D6 refers to information indicating the user of the model corresponding to the operation information D2, such as an ID number assigned to each user. In this embodiment, model information D4 and user information D6 are included in the operation information D2. That is, in this embodiment, the operation information D2 includes information indicating the modeling time, user information D6 indicating the user of the model, and model information D4 indicating the shape of the model.

[0055] When the display control unit 411 selects any one of the multiple operation information D2 displayed on the display screen via the input device 470, it displays the shape of the model corresponding to that operation information D2 as model information D4, and the user of the model corresponding to that operation information D2 as user information D6. Furthermore, when the display control unit 411 selects any one of the multiple 3D modeling devices 100 listed on the left side of the display screen, it displays information indicating the progress of the model being modeled in that 3D modeling device 100 as progress information D5. Additionally, when the display control unit 411 selects any one of the multiple operation information D2 displayed on the display screen via the input device 470, it can also display progress information D5 indicating the progress of the model corresponding to that operation information D2. Furthermore, when the display control unit 411 selects any one of the multiple three-dimensional modeling devices 100 listed on the left side of the display screen, it can also display the shape of the model being modeled in the three-dimensional modeling device 100 as model information D4, and display the user of the model as user information D6.

[0056] Display control unit 411 does not require display. Figure 7 The information displayed includes all of the following: time information D1, operation information D2, remaining quantity information D3, model information D4, progress information D5, and user information D6. Alternatively, at least one of these four information categories may not be displayed.

[0057] Figure 8 This is a flowchart of a schedule adjustment process performed in the control device 400. This process involves the control device 400 managing the modeling schedules of models in multiple 3D modeling devices 100.

[0058] In step S10, the schedule adjustment unit 412 of the control device 400 obtains the modeling data used for modeling in each of the three-dimensional modeling devices 100. The modeling data can be obtained from the storage unit 320 of the control device 400 or from other devices connected to the control device 400 via a network.

[0059] In step S20, the schedule adjustment unit 412 adjusts the operation information for each modeling data.

[0060] Figure 9This diagram illustrates the method for adjusting the operation information in step S20. In this embodiment, the schedule adjustment unit 412 adjusts the operation information to ensure that the maintenance time after modeling for each 3D modeling device 100 is not repeated. The operation information includes the modeling time for modeling the model and the cooling time for cooling the model after modeling. The modeling time is determined based on the shape of the model, the number of layers, the nozzle diameter, etc., and the cooling time is determined based on the shape of the model, the number of layers, the temperature characteristics of the modeling material, the plasticizing temperature, etc. In this embodiment, the operation information of the 3D modeling device 100, namely the modeling start time and the modeling end time, is adjusted in a way that ensures a certain time for removal after cooling and that the maintenance time performed thereafter is not repeated in each 3D modeling device 100. As described above, since the modeling time and cooling time are determined based on the shape of the model, the modeling start time can be automatically adjusted by adjusting the modeling end time. In addition, maintenance includes, for example, cleaning of the 3D modeling device 100 and material replacement.

[0061] exist Figure 8 In step S30, the planning adjustment unit 412 determines the modeling plan of each three-dimensional modeling device 100 based on the operational information that has been adjusted.

[0062] In step S40, the planning adjustment unit 412 transmits modeling data to each three-dimensional modeling device 100 according to the modeling plan determined in step S30. By adopting this method, and according to... Figure 9 The schedule shown describes how the model is created in each of the three-dimensional modeling devices 100. At the end of the model creation process, the user removes the model from each of the three-dimensional modeling devices 100.

[0063] According to the first embodiment described above, the control device 400 displays time information D1, operation information D2, remaining quantity information D3, etc., on the display unit 480. The operation information D2 is displayed corresponding to the time information D1, and the time information D1 is displayed at a specified scale or in a specified time zone. Therefore, multiple 3D modeling devices 100 can be effectively managed.

[0064] Furthermore, in this embodiment, in addition to time information D1, operation information D2, and remaining quantity information D3, the control device 400 also displays model information D4 and progress information D5 on the display unit 480. Therefore, the user can manage each of the three-dimensional modeling devices 100 while checking this information.

[0065] Furthermore, in this embodiment, the modeling schedule is determined in a way that ensures the maintenance time after modeling in each of the three-dimensional modeling devices 100 does not overlap. Therefore, when one worker performs maintenance on multiple three-dimensional modeling devices 100, the scheduled maintenance times will not overlap. Thus, multiple three-dimensional modeling devices 100 can be operated efficiently.

[0066] B. Second implementation method:

[0067] Figure 10 This is an explanatory diagram illustrating the method for adjusting operating information in the second embodiment. In the first embodiment, as... Figure 9 As shown, the schedule adjustment unit 412 adjusts the operation information to ensure that maintenance times after modeling do not repeat. In contrast, in the second embodiment, when different operation information contains the same user information, the schedule adjustment unit 412 adjusts the operation information to make the interval between the modeling completion times of each 3D modeling device 100 shorter than a predetermined interval. In other words, when the operation information in one 3D modeling device 100 and the operation information in other 3D modeling devices 100 contain the same user information, the schedule adjustment unit 412 adjusts the operation information to make the interval between the modeling completion times of one 3D modeling device 100 and the modeling completion times of other 3D modeling devices 100 shorter than a predetermined interval. The predetermined interval is, for example, 0 to 30 minutes. In this embodiment, this interval is set to zero. That is, in this embodiment, the operation information is adjusted to ensure that the modeling completion times of models for the same user are consistent. Figure 10 The diagram shows a schedule for user A to simultaneously model multiple models using modeling devices A through D. The schedule adjustment unit 412 adjusts the modeling completion time for each operation to ensure that the cooling completion time in each of the three-dimensional modeling devices 100 is the same. By employing this method, the user can efficiently retrieve the models modeled in the multiple three-dimensional modeling devices 100. Furthermore, the structure of the three-dimensional modeling system 10 in the second embodiment is the same as that in the first embodiment.

[0068] C. Third implementation method:

[0069] Figure 11 This is an explanatory diagram illustrating the method for adjusting operating information in the third embodiment. In the first embodiment, as... Figure 9 As shown, the schedule adjustment unit 412 adjusts the operation information to prevent the maintenance time after modeling from repeating. In contrast, in the third embodiment, the schedule adjustment unit 412 obtains time specification information for specifying the modeling end time from the user via an input device 470, etc., and adjusts the operation information to end modeling at the specified time. In the third embodiment, as... Figure 11 As shown, when a model for the same user is modeled using multiple 3D modeling devices 100, the operation information is adjusted to ensure that the modeling completion time matches the time specified by the user. By employing this method, the user can efficiently retrieve the model at the desired time. Alternatively, the user can specify different completion times for each of the 3D modeling devices 100. The time specification information can, for example, be included in the modeling data. Furthermore, the structure of the 3D modeling system 10 in the third embodiment is the same as that in the first embodiment.

[0070] D. Fourth Implementation Method:

[0071] Figure 12 This is an explanatory diagram illustrating the method for adjusting operating information in the fourth embodiment. In the first embodiment, as... Figure 9 As shown, the schedule adjustment unit 412 adjusts the operation information to ensure that maintenance time after modeling is not repeated. In contrast, in the fourth embodiment, the schedule adjustment unit 412 adjusts the operation information to ensure that modeling ends within a time period when the user's schedule is empty. Specifically, the schedule adjustment unit 412 obtains the user's schedule information corresponding to the user information contained in the operation information from, for example, a schedule service operating on the Internet or schedule software being used by the user. Then, the schedule adjustment unit 412 determines the time period when the user's schedule is empty and decides the modeling end time to ensure that modeling ends within that time period. By adopting this method, the user can retrieve the model during breaks, such as during a meeting, thus enabling efficient business operations. Furthermore, the structure of the 3D modeling system 10 in the fourth embodiment is the same as in the first embodiment.

[0072] E. Fifth implementation method:

[0073] Figure 13 This is an explanatory diagram illustrating the method for adjusting operating information in the fifth embodiment. In the first embodiment, as... Figure 9As shown, the schedule adjustment unit 412 adjusts the operation information to ensure that maintenance times after modeling do not repeat. In contrast, in the fifth embodiment, when the user information contained in the different operation information has a predetermined relationship, the schedule adjustment unit 412 adjusts the operation information to make the interval between the modeling completion times of each 3D modeling device 100 longer than a predetermined interval. In other words, when there is a predetermined relationship between the user information contained in the operation information of one 3D modeling device 100 and the user information contained in the operation information of other 3D modeling devices 100, the schedule adjustment unit 412 adjusts the operation information to make the interval between the modeling completion times of one 3D modeling device 100 and the modeling completion times of other 3D modeling devices 100 longer than a predetermined interval. Specifically, in this embodiment, when the users corresponding to the user information contained in the different operation information belong to different organizations or companies, the schedule adjustment unit 412 adjusts the operation information to make the interval between modeling completion times one hour or more. By adopting this method, it is possible to suppress the overlap in the retrieval times of models belonging to users of different organizations or companies. Therefore, it is possible to prevent the model from being visually confirmed by a third party when retrieving a highly confidential model. Furthermore, the "pre-defined relationship" is not limited to relationships between different organizations or companies; it can also be, for example, relationships between different users. Additionally, the structure of the 3D modeling system 10 in the fifth embodiment is the same as that in the first embodiment.

[0074] F. Sixth Implementation Method:

[0075] Figure 14 This is an explanatory diagram showing the general structure of the three-dimensional modeling system 10F in the sixth embodiment. In the first embodiment, the models modeled in each of the three-dimensional modeling devices 100 are retrieved by the user. In contrast, in the sixth embodiment, the models modeled in each of the three-dimensional modeling devices 100 are retrieved and transported by an automated guided vehicle 600. The automated guided vehicle 600 is equipped with a battery and wheels driven by the battery, and is configured to move autonomously on a floor on which multiple three-dimensional modeling devices 100 are provided. The automated guided vehicle 600 is provided with multiple storage compartments, in which the models modeled in each of the three-dimensional modeling devices 100 can be stored respectively.

[0076] Figure 15 This diagram illustrates the method for adjusting operating information in the sixth embodiment. In this embodiment, the schedule adjustment unit 412 acquires location information indicating the location of the three-dimensional modeling device 100, and adjusts the operating information based on this location information. The location information is, for example, stored in the storage device 430 of the control device 400. Figure 14 In the example shown, the unmanned transport vehicle 600 retrieves and transports the sculpted objects using the shortest path, following the sequence of sculpting devices A, D, B, and C. Therefore, as... Figure 15 As shown, the schedule adjustment unit 412 adjusts the operating information corresponding to these three-dimensional modeling devices 100 in a manner that the modeling is completed in the order of modeling device A, modeling device D, modeling device B, and modeling device C. By adopting this method, the model created by multiple three-dimensional modeling devices 100 can be effectively retrieved by the unmanned transport vehicle 600.

[0077] G. Seventh Implementation Method:

[0078] Figure 16 This is an explanatory diagram showing the general structure of the three-dimensional modeling system 10G in the seventh embodiment. In the first embodiment, multiple three-dimensional modeling devices 100 are installed in the same location. In contrast, in the seventh embodiment, multiple three-dimensional modeling devices 100 are arranged in different areas, and users retrieve the models created in each three-dimensional modeling device 100 from their homes or workplaces using cars or public transportation.

[0079] Figure 17 This diagram illustrates the method for adjusting operation information in the seventh embodiment. In this embodiment, the schedule adjustment unit 412, similar to that in the sixth embodiment, acquires location information indicating the location of the 3D modeling device 100 and adjusts the operation information based on this location information. At this time, the schedule adjustment unit 412 adjusts the interval between the modeling completion times of each model according to the movement paths and movement times between the various 3D modeling devices 100. By employing this method, the user can effectively retrieve models modeled by the 3D modeling devices 100 located in different areas. The movement paths and movement distances between the various 3D modeling devices 100 can be obtained, for example, from a navigation website operating on the Internet.

[0080] H. Other implementation methods:

[0081] (H1) In the various embodiments described above, at least two of the multiple 3D modeling devices 100 employ different modeling methods. In this case, the schedule adjustment unit 412 can also receive modeling method specification information from the user for each modeling data via the input device 470, specifying a particular modeling method. Modeling methods refer to, for example, material extrusion, inkjet printing, DMD (Direct Metal Deposition), and binder jetting.

[0082] When the scheduling adjustment unit 412 receives a modeling method specification from the user, it sends the modeling data to the 3D modeling device 100 corresponding to that method. Conversely, when no modeling method specification is received, the scheduling adjustment unit 412 sends modeling data for which no modeling method has been specified to a non-operating 3D modeling device 100 and assigns modeling to the model. By adopting this method, the operating rate of multiple 3D modeling devices 100 can be improved. Furthermore, the modeling method specification information may not be received through the input device 470, but may be included in the modeling data, for example.

[0083] (H2) In the third embodiment described above, the operator providing the 3D modeling service implemented by the 3D modeling device 100 may charge the user a higher fee than the usual fee if the user specifies a modeling end time. Alternatively, a pricing system may be adopted where a higher fee is charged if the modeling end time is specified during the day, and a discount is offered if it is specified at night.

[0084] (H3) In the above embodiments, the display control unit 411 is not limited to making Figure 7 The displayed screen is shown on the display unit 480 connected to the control device 400, or it can be shown on other devices connected to the control device 400 via a network.

[0085] (H4) In the above embodiment, the shaping section 110 plasticizes the material by means of the flat screw 40. In contrast, the shaping section 110 may also plasticize the material by means of rotating a straight screw. Furthermore, the shaping section 110 may also plasticize filamentous material by means of a heater.
