Abstract

A three-dimensional shaped object manufacturing method of the invention is a three-dimensional shaped object manufacturing method for manufacturing a three-dimensional shaped object by laminating layers, including: a layer forming step of forming each of the layers by using a layer-forming composition containing particles and a solvent; a first liquid application step of applying, onto the layer in a state of containing the solvent, a liquid that is used to form a solidified part; and a solvent removal step of removing the solvent from the layer. In the first liquid application step, it is preferable that the liquid is applied to a surface of the layer containing the solidified part, in a region that does not overlap the solidified part when the layer is seen in plan view.

First claim

What is claimed is:

1 . A three-dimensional shaped object manufacturing method for manufacturing a three-dimensional shaped object by laminating layers, comprising:
a layer forming step of forming each of the layers by using a layer-forming composition containing particles and a solvent; a first liquid application step of applying, onto the layer in a state of containing the solvent, a liquid used to form a solidified part; and a solvent removal step of removing the solvent from the layer.

2 . The three-dimensional shaped object manufacturing method according to claim 1 ,
wherein at least a portion of the solidified part formed on a surface of an nth layer from below is embedded in an (n+1)th layer from below in the layer forming step performed after the first liquid application step for forming the solidified part (where n is an integer of 1 or more).

3 . The three-dimensional shaped object manufacturing method according to claim 1 ,
wherein, in the first liquid application step, the liquid is applied to a surface of the layer containing the solidified part, in a region containing an area that does not overlap the solidified part when the layer is seen in plan view.

4 . The three-dimensional shaped object manufacturing method according to claim 1 , further comprising,
after the solvent removal step, a second liquid application step of applying a liquid that is used to form a solidified part to the layer in a state in which the solvent has been removed therefrom, so as to allow the liquid to penetrate into the layer.

5 . The three-dimensional shaped object manufacturing method according to claim 1 , further comprising
a third liquid application step of applying, onto a stage on which the layer is not formed, a liquid that is used to form a solidified part.

6 . The three-dimensional shaped object manufacturing method according to claim 1 ,
wherein the layer-forming composition contains an aqueous solvent as the solvent.

7 . The three-dimensional shaped object manufacturing method according to claim 1 ,
wherein the layer-forming composition contains a binder, in addition to the particles and the solvent.

8 . The three-dimensional shaped object manufacturing method according to claim 1 ,
wherein the liquid contains a curable resin.

9 . The three-dimensional shaped object manufacturing method according to claim 1 ,
wherein the liquid contains an acrylic polymerizable compound.

10 . The three-dimensional shaped object manufacturing method according to claim 1 ,
wherein the liquid contains a silicone-based polymerizable compound.

11 . A three-dimensional shaped object manufactured by using the three-dimensional shaped object manufacturing method according to claim 1 .
