The above is the description of the configuration of the modeling apparatus 10 of the present embodiment.

<Method of modeling the modeled object of the first embodiment>
Next, a method of modeling the modeled object M using the modeling apparatus 10 of the present embodiment will be described with reference to the drawings.

[Data conversion]
First, when the control unit 50 receives the data from the external device, the control unit 50 slices the data of the three-dimensional object VM included in the data into the three-dimensional object VM with a thickness determined by a cross section perpendicular to the height direction. It is converted into layer data for forming each layer LR.

Layer LR1 is formed. Specifically, the control unit 50 ejects the first droplet D1 to the first ejection unit 22 at the position P2 while moving the base BD located at the position P1 (which is regarded as the home position) in the positive direction. (See FIGS. 3A, 3B and 4). Next, the control unit 50 operates the first irradiation device 32 as the table BD moves in the positive direction to irradiate the first droplet D1 with light at the position P3 (see FIGS. 3B and 4). As a result, the first droplet D1 that has landed on the platform BD is irradiated with light and cured. Next, the control unit 50 ejects the second droplet D2 between the first droplets D1 by the second ejection unit 24 at the position P4 as the table BD moves in the positive direction. Next, when the table BD moves in the positive direction by the moving device MA and reaches the position P5, the control unit 50 operates the second irradiation device 34 that has moved together with the table BD to irradiate the second droplet D2 with light. (See FIG. 3C). As a result, the second droplet D2 is irradiated with light and cured. Further, the light from the second irradiation device 34 is also irradiated to the first droplet D1. Note that T in the timing chart of FIG. 4 represents time. Then, in the timing chart of FIG. 4, the positive side of the table BD shows the state of moving in the forward direction, and the reverse side shows the state of moving in the reverse direction. H of the irradiation device 32 and the second irradiation device 34 indicate a state in which they are operating, and L indicates a state in which they are not operating. The table BD reaches the position P5 when the modeling operation starts and the time t3 elapses, and is irradiated with light from the second irradiation device 34 in a state where the table BD is located at the position P5 during the period from the time t3 to the time t4.

As described above, the control unit 50 moves the base BD from the other end side (position P1) in the device width direction to the one end side (position P5) by the moving device MA (the base BD reaches one of the switching positions for reciprocating movement). ), A layer LR formed by curing the first droplet D1 and the second droplet D2 (see layer LR1 in FIGS. 1 and 3E) is formed on the base BD. The control unit 50 moves the table BD to the position P5 by the moving device MA, and then further moves the table BD downward in the device height direction by the thickness of the layer LR by the moving device MA, and then moves the table BD to the position P5. The formation of layer LR1 is completed.

[Formation of the second and subsequent layers]
The second and subsequent layers LR are formed by repeating the above-mentioned operation of forming the first layer LR1 by reversing the moving direction of the table BD (see FIGS. 3A to 3E). Then, when the control unit 50 superimposes all the layers LR on each component other than the control unit 50 according to the layer data, the control unit 50 moves the base BD to the position P1 and of the present embodiment. The modeling method of the three-dimensional object VM using the modeling device 10 is completed. When the three-dimensional object VM is removed from the modeling device 10 by the operator after the completion of the modeling method of the three-dimensional object VM using the modeling device 10, the worker removes the cured support material from the three-dimensional object VM and forms the model. Object M is modeled.

The above is the description of the modeling method of the modeled object M of the present embodiment.

<Effect of the first embodiment>
Next, the effects (first and second effects) of the present embodiment will be described with reference to the drawings.

[First effect]
The first effect is that the second irradiation device 34 reciprocates together with the table BD. The first effect will be described by comparing the modeling device 10 of the present embodiment with the modeling device 10A (see FIG. 5) of the first comparative embodiment described below. In the following description, when the same parts or the like as the parts or the like used in the modeling device 10 of the present embodiment are used for the modeling device 10A of the first comparative embodiment, the reference numerals of the parts or the like are used as they are without drawing. ..

In the modeling device 10A (see FIG. 5) of the first comparative embodiment, unlike the modeling device 10 (see FIG. 1) of the present embodiment, the second irradiation device 34 does not reciprocate with the table BD. Then, in the modeling device 10A of the first comparative form, the second irradiation device 34 is arranged at the position P1 and the position P5, respectively. That is, the modeling device 10A of the first comparative form includes two second irradiation devices 34. Further, the modeling device 10A of the first comparative form does not include a plurality of shutters 40. The first comparative embodiment is the same as that of the present embodiment except for the above points.

On the other hand, in the case of the modeling device 10 of the present embodiment, as shown in FIGS. 1 and 2, the second irradiation device 34 reciprocates together with the table BD, and the second irradiation is performed at the positions P1 and P5. The device 34 irradiates light toward the droplet D that has landed on the base BD.

Therefore, according to the modeling device 10 of the present embodiment, the second irradiation is performed as compared with the modeling device in which the second irradiation device 34 is arranged at the switching positions P1 and P5 in the relative movement direction of the table BD with respect to the discharge means 20. The number of devices 34 is small. In other words, according to the modeling device 10 of the present embodiment, as compared with the modeling device in which the two second irradiation devices 34 are arranged at the switching positions P1 and P5 in the relative movement direction of the table BD with respect to the discharge means 20. Low cost.

[Second effect]
The second effect is that the shutter 40 is provided. The second effect will be described by comparing the modeling device 10 of the present embodiment with the modeling device 10A (see FIG. 5) of the first comparative embodiment.

Unlike the modeling device 10 (see FIG. 1) of the present embodiment, the modeling device 10A (see FIG. 5) of the first comparative embodiment does not include the shutter 40. Therefore, in the case of the first comparative mode, the light reflected after being irradiated toward the droplet D by the second irradiation device 34 may reach the plurality of nozzles N of the first ejection unit 22 and the second ejection unit 24. There is. As a result, the droplet D in the nozzle N is cured, and the nozzle N of the first ejection portion 22 and the second ejection portion 24 is clogged with the cured droplet D.

On the other hand, in the modeling device 10 of the present embodiment, as shown in FIGS. 1 and 2, a plurality of shutters 40 are arranged one by one on the outside of the discharging means 20 in the width direction of the device. Therefore, when the second irradiation device 34 irradiates the droplet D that has landed on the base BD, the shutter 40 on the center side in the device width direction of the pair of shutters 40 is liquid after being irradiated from the second irradiation device 34. The amount of light reflected by the droplet D and directed to the plurality of nozzles N is reduced.

Therefore, according to the modeling device 10 of the present embodiment, the nozzle N is used as compared with the modeling device that does not have a reduction wall that reduces the amount of light reflected toward the nozzle N after being irradiated on the droplet D. Curing of the droplet D is suppressed.

The above is the description of the effect of this embodiment. Further, the above is the description of the first embodiment.

<< 1st modified example of the 1st embodiment (1st modified example) >>
Next, the modeling apparatus 10B of the first modification will be described with reference to FIG. In the following description, when the same parts or the like as the parts or the like used in the modeling device 10 of the first embodiment are used for the modeling device 10B of the present modification, the reference numerals of the parts or the like are used as they are without drawing. ..

<Structure of modeling equipment and modeling method of modeled object>
Unlike the modeling device 10 (see FIG. 1) of the first embodiment, the modeling device 10B (see FIG. 6) of this modification does not include the first irradiation device 32. Further, the modeling device 10B of the present modification is a range in which the two shutters 40 on the center side in the device width direction (relative movement direction of the base BD) face each other, and the discharge means 20 and the second irradiation in the device height direction.
