Three-dimensionally shaped article production member, three-dimensionally shaped article production apparatus, three-dimensionally shaped article production method, and three-dimensionally shaped article

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.

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 .
