  Next, an example of operation | movement of the three-dimensional modeling apparatus 10 of this embodiment is demonstrated. Here, a case where the first cartridge 15A placed on the first placement unit 41 is replaced will be described.

  First, as shown in FIG. 5, the rotation of the first roller gear 16A is stopped by stopping the driving of the motor 43M. Thereby, the conveyance of the resin material 46P accommodated in the first cartridge 15A is stopped. That is, the discharge of the resin material 46P from the first nozzle 72A is stopped.

  Next, as shown in FIG. 3, by driving a motor 100M (see FIG. 4), the moving unit 100 is moved in the direction of arrow F1 in FIG. As a result, as shown in FIG. 6, the first modeling head 71A is guided by the first through hole 107A (see FIG. 9) and the second through hole 107B and moves upward, and the second modeling head 71B is The first through hole 107A and the second through hole 107B are guided and moved downward.

As a result, the resin material 46P in the first resin supply path 46 is returned to the first cartridge 15A by the upward movement of the first modeling head 71A. The resin recovery tank 102 that has been disposed below the second nozzle 72B before the movement unit 100 moves is disposed below the first nozzle 72A. Then, as shown in FIG. 5, by driving the motor 44M, the second roller gear 16B is rotated in the direction of the arrow I1 in FIG. Thereby, the resin material 47P accommodated in the second cartridge 15B is conveyed. That is, the resin material 47P is discharged from the second nozzle 72B.

  As shown in FIG. 7, when the moving unit 100 is further moved in the direction of the arrow F <b> 1 in FIG. 7, the cutter 101 cuts the resin material 46 </ b> P in the first resin supply path 46. More specifically, as shown in FIG. 14, the cutter 101 moves to the front of the first resin supply path 46 by moving the moving unit 100 (see FIG. 7). As shown in FIG. 15, by further moving the moving unit 100, the cutter 101 further moves in the direction of the arrow F1 in FIG. 15 and cuts the resin material 46P in the first resin supply path 46. Accordingly, the first resin supply path 46 is divided into a resin material 46P positioned above the cutter 101 and a cut resin material 46PP positioned below the cutter 101.

  Next, by moving the moving unit 100 in the direction of the arrow F2 in FIG. 7, the cutter 101 is disposed at a position that does not overlap the first resin supply path 46, and the resin recovery tank 102 is disposed below the first nozzle 72A. Deploy.

  As shown in FIG. 16, by driving a motor 43M (see FIG. 5), the first roller gear 16A is rotated in the direction of the arrow H1 in FIG. Thereby, the resin material 46P accommodated in the first cartridge 15A is sent out. As a result, the resin material 46PP cut by the sent resin material 46P is pushed into the first modeling head 71A, and a part of the cut resin material 46PP is transferred from the first nozzle 72A to the resin recovery tank 102. Discharged. Another part of the cut resin material 46PP remains in the first modeling head 71A. After all of the cut resin material 46PP present in the first resin supply path 46 is pushed into the first modeling head 71A by the rotation of the first roller gear 16A, the first roller gear 16A is moved to the arrow H2 in FIG. Rotate in the direction of. Accordingly, as shown in FIG. 17, the first roller gear 16A returns the resin material 46P sent from the first cartridge 15A to the first resin supply path 46 to the first cartridge 15A.

  Next, as shown in FIG. 2, the first cartridge 15 </ b> A placed on the first placement unit 41 is moved to the storage unit 54 </ b> X of the second table 50 by the carriage 60. The arbitrary cartridge 15 placed on the storage unit 54 of the second table 50 is moved to the first placement unit 41 by the carriage 60. As shown in FIG. 5, the first driven gear 17A of the first cartridge 15A mounted on the first mounting portion 41 meshes with the first drive gear 43A.

  As shown in FIG. 5, the first roller gear 16A is rotated in the direction of the arrow H1 in FIG. 5 by driving the motor 43M. Thereby, as shown in FIG. 18, the resin material 46 </ b> P accommodated in the first cartridge 15 </ b> A is sent out to the first resin supply path 47. As shown in FIG. 19, by sending the resin material 46P to the first modeling head 71A, the resin material 46PP remaining in the first modeling head 71A is discharged into the resin recovery tank 102. As shown in FIG. 20, the resin material 46P is discharged until all of the resin material 46PP remaining in the first modeling head 71A is discharged into the resin recovery tank 102 and the resin material 46P is filled in the first modeling head 71A. To the first modeling head 71A. The resin material 46P may be sent out to the first modeling head 71A until a part of the resin material 46P is recovered in the resin recovery tank 102. After the resin material 46P is filled in the first modeling head 71A, the driving of the motor 43M is stopped, and the rotation of the first roller gear 16A is stopped. Thereby, the conveyance of the resin material 46P accommodated in the first cartridge 15A is stopped. As described above, the first cartridge 15A placed on the first placement portion 41 is replaced, and the first modeling head 71A is made usable.

  As described above, according to the three-dimensional modeling apparatus 10, when the resin material 46 </ b> P discharged from the first nozzle 72 </ b> A of the first modeling head 71 </ b> A is changed, the carriage 60 is used for the first mounting portion of the first table 40. The first cartridge 15 </ b> A placed on 41 is moved to the second table 50. Then, when the second table 50 rotates, one cartridge 15 to be used next among the plurality of cartridges 15 placed on the second table 50 is arranged on the side of the first placement portion 41. . Thereafter, the carriage 60 moves the cartridge 15 to the first placement unit 41. Thus, by changing the cartridge 15 placed on the first placement portion 41, the resin material is transferred from the plurality of cartridges 15 to the first modeling head 71A with respect to one first modeling head 71A. Can be supplied. Therefore, it is possible to form a three-dimensional structure having a larger number of colors than the conventional one or a three-dimensional structure having a larger number of materials than the conventional one-time structure. The cartridge 15 placed on the first placement unit 41 is automatically replaced by the carriage 60. For this reason, the burden on the operator is reduced and the work efficiency is improved.

  Further, the resin material 46P accommodated in the first cartridge 15A placed on the first placement portion 41 is discharged from the first nozzle 72A of the first modeling head 71A via the first resin supply path 46, and the first The resin material 47P accommodated in the second cartridge 15B placed on the second placement section 42 is discharged from the second nozzle 72B of the second modeling head 71B via the second resin supply path 47. For example, the second cartridge 15B placed on the second placement part 42 can be replaced when a three-dimensional shaped object is being shaped using the first modeling head 71A. In this manner, the second cartridge 15B used in the second modeling head 71B can be exchanged while modeling the three-dimensional modeled object using the first modeling head 71A. For this reason, when modeling a three-dimensional structure using a plurality of types of resin materials, the replacement time of the cartridge 15 is shortened, and the three-dimensional structure can be efficiently modeled.

  According to the three-dimensional modeling apparatus 10 of the present embodiment, as shown in FIG. 6, the resin recovery tank 102 is located below the first nozzle 72A. For this reason, after the first cartridge 15A placed on the first placement part 41 is replaced, the resin material 46P remaining in the first nozzle 72A of the first modeling head 71A is discharged into the resin recovery tank 102. Thereby, a new resin material can be discharged from the first nozzle 72A. As shown in FIG. 3, the resin recovery tank 102 is located below the second nozzle 72B. For this reason, the resin material 47P remaining in the second nozzle 72B of the second modeling head 71B is discharged into the resin recovery tank 102 after the second cartridge 15B placed on the second placement unit 42 is replaced. Thereby, a new resin material can be discharged from the second nozzle 72B. Furthermore, since the resin materials 46P and 47P remaining in the first nozzle 72A of the first modeling head 71A and the second nozzle 72B of the second modeling head 71B are respectively discharged into the resin recovery tank 102, the resin materials 46P and 47P are discharged. Compared to the case of discharging onto the stage 80, the modeling area for modeling the three-dimensional modeled object on the stage 80 becomes larger, and the stage 80 can be used effectively.

  According to the three-dimensional modeling apparatus 10 of the present embodiment, as shown in FIG. 5, when the resin material 46P is discharged from the first nozzle 72A, the first roller gear 16A is placed on the first placement portion 41. When the resin material 46P is reliably supplied from the first cartridge 15A to the first nozzle 72A and the resin material 47P is discharged from the second nozzle 72B, the second cartridge placed on the second placement portion 42 by the second roller 16B. The resin material 47P is reliably supplied from 15B to the second nozzle 72A. On the other hand, when the first cartridge 15A placed on the first placement portion 41 and the second cartridge 15B placed on the second placement portion 42 are replaced, the first roller gear 16A and the second roller gear 16B change the first cartridge 15A. The resin materials 46P and 47P once sent out from the first cartridge 15A and the second cartridge 15B are returned to the original first cartridge 15A and the second cartridge 15B, respectively. For this reason, waste of resin material 15A, 15B can be suppressed.

  According to the three-dimensional modeling apparatus 10 of the present embodiment, as shown in FIG. 5, the first table 40, the motor 43M that drives the first roller gear 16A, and the motor 44M that drives the second roller gear 16B are provided. ing. Accordingly, the first roller gear 16A driven by the motor 43M provided on the first table 40 conveys each resin material accommodated in the plurality of cartridges 15 to the first modeling head 71A and is provided on the first table 40. The second roller gear 16B driven by the motor 44M can transport each resin material accommodated in the plurality of cartridges 15 to the second modeling head 71B. Compared with the case where each cartridge 15 is provided with a motor, the structure of the cartridge 15 can be simplified and the cost of the cartridge 15 can be reduced.

  According to the three-dimensional modeling apparatus 10 of the present embodiment, the resin material 46P in the first resin supply path 46 and the resin material 47P in the second resin supply path 47 can be cut using one cutter 101. . For this reason, the structure of the three-dimensional modeling apparatus 10 is simplified. Further, since the resin material 46P in the first resin supply path 46 and the resin material 47P in the second resin supply path 47 are cut by the cutter 101, the first cartridge 15A mounted on the first mounting portion 41 and The replacement of the second cartridge 15B mounted on the second mounting portion 42 can be performed smoothly.

  According to the three-dimensional modeling apparatus 10 of the present embodiment, as shown in FIG. 3, the cutter 101 and the resin recovery tank 102 move integrally. Compared to the case where the cutter 101 and the resin recovery tank 102 move separately, the structure of the three-dimensional modeling apparatus 10 is simplified.

  According to the three-dimensional modeling apparatus 10 of this embodiment, as shown in FIG. 3, the first modeling head 71A includes a first heater 77A, and the second modeling head 71B includes a second heater 77B. When the first heater 77A is provided in the first resin supply path 46 or when the second heater 77B is provided in the second resin supply path 47, the first resin supply path 46 or the second resin supply path There is a possibility that the thermoplastic resin softened in 47 is cooled and hardened before being discharged from the first nozzle 72A or the second nozzle 72B. However, according to the three-dimensional modeling apparatus 10 of this embodiment, it is possible to prevent the thermoplastic resin from being cooled and cured before the thermoplastic resin is discharged from the first nozzle 72A and the second nozzle 72B. Further, when the first modeling head 71A and the first resin supply path 46 are arranged apart from each other, or when the second modeling head 71B and the second resin supply path 47 are arranged apart from each other, the first If the first heater 77A is provided in the resin supply path 46 or the second heater 77B is provided in the second resin supply path 47, the softened thermoplastic resin 46P is not sent to the first nozzle 72A and the first modeling is performed. The thermoplastic resin 47P that leaks to the outside from between the head 71A and the first resin supply path 46 or is not sent to the second nozzle 72B does not pass between the second modeling head 71B and the second resin supply path 47. There is a risk of leaking outside. However, according to the three-dimensional modeling apparatus 10 of the present embodiment, since the first modeling head 71A includes the first heater 77A and the second modeling head 71B includes the second heater 77B, the softened thermoplastic resin 46P. , 47P are reliably conveyed to the first nozzle 72A and the second nozzle 72B.

  According to the three-dimensional modeling apparatus 10 of the present embodiment, as shown in FIG. 1, the first table 40 is disposed above the first modeling head 71A and the second modeling head 71B. Thereby, compared with the case where the 1st table 40 is arrange | positioned to the side of 1st modeling head 71A and 2nd modeling head 71B, the horizontal width of the three-dimensional modeling apparatus 10 can be made small. For this reason, the structure of the three-dimensional modeling apparatus 10 becomes compact.

  According to the three-dimensional modeling apparatus 10 of the present embodiment, as illustrated in FIG. 2, the first cartridge 15 </ b> A or the second mounting unit 42 in which the carriage 60 is mounted on the first mounting unit 41 of the first table 40.
