Abstract

A shaping plate to be set on a shaping stage of a shaping system for performing shaping by an additive manufacturing method includes a water-insoluble base substrate and an underlying layer containing a water-soluble material on at least one surface of the base substrate, wherein the base substrate has a plurality of through holes that extend in the direction intersecting the surface provided with the underlying layer.

First claim

What is claimed is:

1. A method for manufacturing a three-dimensional object that is substantiation of a three-dimensional model by using a shaping apparatus including
a shaping stage having a surface and having a setting portion for setting a shaping plate on the surface, and
a shaping portion for stacking a shaping material on the shaping stage in accordance with slice data of the three-dimensional model,

the method comprising the steps of:
setting the shaping plate on the shaping stage; and
stacking the shaping material on the shaping plate,

wherein the shaping plate comprises:
a base substrate made of a water insoluble material; and
an underlying layer containing a water-soluble material provided at least on a surface on which the shaping material is to be stacked;
wherein the base substrate has a plurality of through holes that extend in the direction intersecting the surface provided with the underlying layer.

2. The method for manufacturing a three-dimensional object according to claim 1 , further comprising the step of bringing the underlying layer into contact with a solvent containing water through the through holes of the shaping plate after repetition of the stacking of the shaping material in accordance with the slice data.

3. The method for manufacturing a three-dimensional object according to claim 1 ,
wherein the shaping material contains a structural material for constituting the three-dimensional object and a support material for supporting stacking of the structural material, and
the underlying layer is formed of the same material as the support material.

4. The method for manufacturing a three-dimensional object according to claim 1 , wherein regarding the through hole, the hole diameter at a position far from the surface provided with the underlying layer is larger than the hole diameter at a position near to a shaping surface.

5. The method for manufacturing a three-dimensional object according to claim 1 , wherein the minimum hole diameter of the through hole is 1 mm or more.

6. The method for manufacturing a three-dimensional object according to claim 1 , wherein the volume ratio of the water-soluble material contained in the underlying layer is 30% or more.

7. The method for manufacturing a three-dimensional object according to claim 1 , wherein the underlying layer contains a water-soluble carbohydrate.

8. The method for manufacturing a three-dimensional object according to claim 7 , wherein the water-soluble carbohydrate is water-soluble dietary fiber or glucide.

9. The method for manufacturing a three-dimensional object according to claim 8 , wherein the glucide is selected from the group consisting of sucrose, lactose, maltose, trehalose, melezitose, stachyose, and maltotetraose.

10. The method for manufacturing a three-dimensional object according to claim 1 , wherein the underlying layer contains a water-insoluble material.

11. The method for manufacturing a three-dimensional object according to claim 10 , wherein the water-insoluble material is fibrous.

12. The method for manufacturing a three-dimensional object according to claim 11 wherein the water-insoluble material is cellulose fiber or aramid fiber.

13. The method for manufacturing a three-dimensional object according to claim 1 , wherein the underlying layer has a mesh structure or a porous structure.

14. The method for manufacturing a three-dimensional object according to claim 1 , wherein the base substrate is composed of any one of a polymerized material, a metal material, and a ceramic material.

15. The method for manufacturing a three-dimensional object according to claim 1 , wherein an area C of the underlying layer in plan view from the surface, on a shaping side, of the base substrate and an actual contact area D between the base substrate and a region containing the water-soluble material satisfy the relationship represented by C<D.

16. The method for manufacturing a three-dimensional object according to claim 1 , wherein a region containing the water-soluble material intrudes inside the through holes.
