[0080] figure 1 A block diagram of a three-dimensional shaping system 100 according to a first embodiment of the present invention is illustrated. An example in which a three-dimensional forming device is applied in an inkjet method is explained as an example of a three-dimensional forming device. The three-dimensional forming system 100 is suitable for jetting liquid forming materials in an inkjet manner, and then solidifying and stacking these materials to manufacture arbitrary shaped objects. A model material MA and a support material SA are used as the forming material, wherein the model material MA is configured to form a final shaped object, and the support material SA is configured to be formed to support a protruding portion of the model material MA and finally removed.

Embodiment 1

[0154] (Example 1: When molding MS at the same time)

[0155] First, an example of simultaneous molding of a mold material MA and a support material SA as a first embodiment will be described. When using simultaneous forming, the model material MA and support material SA are injected in a single pass of the head. Figure 14 Data processing is performed on the forming object data as shown in (a), and follows Figure 14 The sequence shown in (b) shapes the individual layers (slices S1 to S6). In this example, it is assumed that the individual layers are formed in a single slice portion by a single reciprocating motion of the head.

[0156] In traditional simultaneous forming, according to Figure 14 The order shown in (a) sequentially stacks the model material MA and support material SA for each slice. Specifically, a block B1 of support material SA is jetted and cured in slice S1, and after forming the support material layer (block B1), the support material layer (block B2)...

Embodiment 2

[0161] (Example 2: MS independent forming)

[0162] An example of simultaneous forming in which a model material and a support material are simultaneously formed has been described above, but the present invention is not limited in this respect, and the present invention can also be applied to independent forming in which a model material and a support material are separately formed. Independent shaping is used in the second embodiment below, and reference is made to Figure 18 to Figure 21 Describes the stacking sequence of forming materials in independent forming. Use independent forming to form model material MA and support material SA, for Figure 21 Perform data processing on the shaped data shown in (a) to follow Figure 21 (b) Sequential shaping of each layer (slices S1 to S6) shown. In this example, it is assumed that the individual layers are formed in a single slice portion by a single reciprocating motion of the head.

[0163] In the usual independent forming, a...

Abstract

The invention provides a three-dimensional forming device of a three-dimensional forming object, a three-dimensional forming method, and a setting data creation device for the three-dimensional forming device. A control device 10 is used for controlling the driving of a horizontal driving device, spraying and curing molding materials in one piece by a molding material spraying device, controlling a vertical driving device and moving to the spraying position of the cured piece, spraying and curing the molding materials on the next layer to continuously laminate pieces. A hollow part ES is formed in the piece on the interface of the corresponding molding materials of different types, a mold material MA and a support material SA on the interface are changed from one molding material into the other molding material along the lamination direction of molding objects. The control device 10 executes the control to prevent the molding materials from being sprayed by the molding material spraying device on the position corresponded with the hollow part ES or reduce the spraying amount of the molding material.

Description

technical field [0001] The present invention relates to a three-dimensional forming device for manufacturing a three-dimensionally formed object in an inkjet manner, a three-dimensional forming method, a setting data creating device for the three-dimensional forming device, a setting data creating program for the three-dimensional forming device, and a computer-readable recording medium. Background technique [0002] There is known a device having a function of setting three-dimensional data as basic data of a formed object as an arbitrary pose on a computer screen, creating data for each section divided into a plurality of parallel planes at relative heights based on the set pose, and creating data based on each layer A three-dimensional molded object is formed by successively laminating resins to create a molded body serving as a three-dimensional model of the molded body. [0003] In the field of rapid prototyping (RP) applied to prototype development such as product deve...
