As shown in FIG. 3, the control unit 580 has a control circuit 582, and the control circuit 582 is connected to the three-dimensional data generator 100 (see FIG. 1) via the network 700 (see FIG. 1) and the communication interface 584. ) Is input.

Then, when the modeling of a constant width in the main scanning direction (X-axis direction) is completed, the control circuit 582 causes the Y-axis direction moving mechanism 536 to move the head portion 530 in the sub-operation direction (Y-axis direction). Furthermore, modeling in the constant width direction in the main scanning direction is repeated.

The output of the modeled object 800 using the three-dimensional data defining the shape at the same time is instructed to the three-dimensional modeling apparatus 500. At this time, the output instruction unit 112 instructs the modeled object main body 810 to output using the modeling material, and the positioning unit 820 to output using the support material.

FIG. 6 shows a first example of the model 800. The modeled object 800 is instructed to be output by the output indicating unit 112, and has a modeled object main body 810 and a positioning unit 820 as shown in FIG. The positioning unit 820 has a shape that guides the movement of the other member 900 positioned with respect to the modeled object body 810 to the modeled object body 810. Specifically, the positioning portion 820 is formed with a guide groove 822 that guides the other member 900 toward the modeled object main body 810.

The other member 900 may be a modeled object output by the three-dimensional modeling device 500, or may be a modeled object other than the modeled object output by the three-dimensional modeling device 500.

The positioning unit 820 is formed from a support material as described above. Therefore, after the other member 900 is positioned on the modeled object main body 810, it can be removed from the modeled object main body 810 by, for example, washing with water.

FIG. 7 shows a second example of the model 800. The model 800 is instructed to be output by the output instruction unit 112. In the first example described above, two positioning portions 820 are provided so as to surround a part of the upper surface of the modeled object main body 810. On the other hand, in this second example, as shown in FIG. 7, one positioning portion 820 is provided so as to surround the entire upper surface of the modeled object main body 810.

FIG. 8 shows a second example of the model 800 shown in FIG. 7, a third example of the model 800, and a fourth example of the model 800 in comparison with each other. A) is a plan view showing a second example of the model 800, FIG. 8 (B) is a plan view showing a third example of the model 800, and FIG. 8 (C) is a third example of the model 800. It is a top view which shows the example of 4.

In each of these modeled objects 800, the output is instructed by the output indicating unit 112, and as shown in FIG. 8, in the second example, the positioning unit 820 is the modeled object main body 810. It is arranged so as to cover the four sides of the upper surface. Further, in the third example, the positioning portion 820 is arranged so as to cover one side of the upper surface of the modeled object main body 810. Further, in the fourth example, the positioning portion 820 is arranged so as to cover the two vertices of the upper surface of the modeled object 800. Here, when the amount of the support material for modeling the positioning portion 820 is compared, the amount of the supporting material for modeling the positioning portion 820 is the largest in the second example shown in FIG. 8 (A). The third example shown in FIG. 8 (B) is the second most common, and the fourth example shown in FIG. 8 (C) is the least.

Specifically, it is determined by the three-dimensional data of the positioning unit 820 generated by the positioning unit data generation unit 108 based on the operator's instruction received by the data generation instruction receiving unit 106.

In FIG. 9, a fifth example of the model 800 is shown in the upper row, and a second example of the model 800 is shown in the lower row (see FIG. 7). In the example shown in FIG. 9, the second example of the model 800 and the fifth example of the model 800 are never positioned relative to each other. Positioning is performed by inserting the fifth model 800 into a recess formed on the upper surface of the second example of the model 800 so as to be surrounded by the position determination portion 820.

In the fifth example of the modeled object 800, the output is instructed by the output indicating unit 112, and as shown in FIG. 9, it has a modeled object main body 810 and a positioning unit 820. The positioning unit 820 has a shape that restricts the movement of the model 800 toward the second example of the fifth example of the model 800. That is, when the fifth example of the modeled object 800 approaches the second example of the modeled object 800, the positioning unit 820 of the fifth example of the modeled object 800 becomes the positioning unit of the second example of the modeled object 800. Contacting the 820 makes it impossible to move further towards the second example of the model 800 in the fifth example of the model 800.

In each of these examples, the positioning unit 820 stacks the two sculptures 800 so that one upper surface of the sculpture 800 and the other lower sculpture of the sculpture 800 coincide with each other. The two modeled objects are shaped so that the directions of the main bodies 810 match.

In the sixth, seventh, and eighth examples of the model 800, one of the positioning portions 820 is such that the entire modeling body 810 is embedded in the positioning portion 820. It was being modeled. On the other hand, in the ninth example, three positioning portions 820 are formed so as to protrude from the modeled object main body 810. Also in this ninth example, when the positioning portion 820 overlaps the two shaped objects 800 so that one upper surface of the modeled object 800 and the other lower surface of the modeled object 800 are aligned with each other, The two modeled objects are shaped so that the directions of the main bodies 810 match.

FIG. 12A shows a tenth example of the model 800. The model 800 is instructed to be output by the output instruction unit 112. As shown in FIG. 10, the tenth example of the modeled object 800 has a modeled object main body 810 and a positioning portion 820, and the modeled object main body 810 has a U-shaped cross section. Further, the positioning portion 820 has a shape that suppresses deformation of the modeled object main body 810. More specifically, the positioning portion 820 is shaped so that both ends of the U-shaped shaped object main body 810 are embedded.

FIG. 12B shows a first comparative example of the model 800. In this comparative example, both ends of the U-shaped model body 810 are not embedded in the positioning portion 820. Therefore, the modeled object main body 810 in this comparative example is compared with the tenth example of the modeled object 800 shown in FIG. 12 (A) in the direction indicated by the arrow a shown in FIG. 12 (B) or by the arrow b. Easy to deform in the indicated direction.

FIG. 13A shows an eleventh example of the model 800. The model 800 is instructed to be output by the output instruction unit 112.

It is output so as to be supported by the model body 810 from below in the direction of gravity.

FIG. 13B shows a second comparative example of the model 800. In this comparative example, the positioning portion 820 is not supported from the lower side in the direction of gravity by the modeled object main body 810, and a space is formed between the lower end portion and the installation surface. For this reason, the positioning portion 820 in this comparative example is more difficult to model than the positioning portion 820 in the eleventh example of the modeled object 800 shown in FIG. 13 (A).
