Abstract

A three-dimensionally shaped article production member is a member used in a three-dimensionally shaped article production apparatus for producing a three-dimensionally shaped article by stacking a layer formed using a composition containing particles. The member is placed on a stage and comes in contact with the layer, and has a portion provided with pores in a contact surface with the layer.

First claim

What is claimed is:

1 . A three-dimensionally shaped article production member, which is a member used in a three-dimensionally shaped article production apparatus for producing a three-dimensionally shaped article by stacking a layer formed using a composition containing particles, wherein
the member is placed on a stage and comes in contact with the layer, and the member has a portion provided with pores in a contact surface with the layer.

2 . The three-dimensionally shaped article production member according to claim 1 , wherein the three-dimensionally shaped article production member is in the form of a plate.

3 . The three-dimensionally shaped article production member according to claim 1 , wherein the three-dimensionally shaped article production member includes a first portion which has the pores and a second portion which does not have the pores or has the pores which are sealed.

4 . The three-dimensionally shaped article production member according to claim 3 , wherein the second portion is provided in a region which does not overlap with a portion constituting a tangible part of the three-dimensionally shaped article in the layer when the layer is viewed in plan view.

5 . The three-dimensionally shaped article production member according to claim 1 , wherein the three-dimensionally shaped article production member has a portion constituted by a sintered body of particles constituted by a metal material or a ceramic material.

6 . The three-dimensionally shaped article production member according to claim 1 , wherein the average pore diameter of the pores is 0.1 μm or more and 100 μm or less.

7 . The three-dimensionally shaped article production member according to claim 1 , wherein the composition contains a solvent in addition to the particles.

8 . A three-dimensionally shaped article production apparatus, comprising the three-dimensionally shaped article production member according to claim 1 .

9 . A three-dimensionally shaped article production apparatus, which is an apparatus for producing a three-dimensionally shaped article by stacking a layer formed using a composition containing particles, comprising:
a three-dimensionally shaped article production member having pores; a stage, on which the three-dimensionally shaped article production member is placed; and a suction unit for sucking the layer through the pores.

10 . A three-dimensionally shaped article production method, which is a method for producing a three-dimensionally shaped article by stacking a layer, comprising:
a layer forming step of forming the layer using a layer forming composition containing particles in a region which overlaps with a three-dimensionally shaped article production member having pores when viewed in plan view; and a bonded part forming step of forming a bonded part by bonding the particles to one another, wherein a series of these steps is performed repeatedly, and when performing a series of these steps, the layer is sucked through the pores.

11 . The three-dimensionally shaped article production method according to claim 10 , wherein the bonded part is formed by applying a binding solution to the layer formed using the layer forming composition.

12 . A three-dimensionally shaped article, which is produced using the apparatus according to claim 8 .

13 . A three-dimensionally shaped article, which is produced using the apparatus according to claim 9 .

14 . A three-dimensionally shaped article, which is produced using the production method according to claim 10 .

15 . A three-dimensionally shaped article, which is produced using the production method according to claim 11 .
