Abstract
Official abstract text for this publication.
A three-dimensional shaped article shaping stage, which is used in a three-dimensional shaped article production apparatus for producing a three-dimensional shaped article by stacking layers to form a stacked body, is attachable to and detachable from the production apparatus, has a forming surface on which the stacked body is to be formed, and in which an organic film having a lower melting point than a constituent material is formed on the forming surface, is used. By using such a shaping stage, it becomes possible to easily separate the stacked body of the three-dimensional shaped article formed by stacking layers on the shaping stage from the shaping stage.
First claim
Opening claim text (preview).
What is claimed is: 1 . A three-dimensional shaped article shaping stage, which is used in a three-dimensional shaped article production apparatus for producing a three-dimensional shaped article by stacking layers to form a stacked body, wherein the shaping stage is attachable to and detachable from the production apparatus, the shaping stage has a forming surface on which the stacked body is to be formed, and an organic film having a lower melting point than a constituent material of the three-dimensional shaped article is formed on the forming surface. 2 . The three-dimensional shaped article shaping stage according to claim 1 , wherein the organic film contains a component having a higher melting point than the constituent material. 3 . The three-dimensional shaped article shaping stage according to claim 1 , wherein the organic film contains an acrylic resin. 4 . The three-dimensional shaped article shaping stage according to claim 1 , wherein the shaping stage is constituted by a high-melting point material having a higher melting point than the constituent material, and the high-melting point material contains at least one of alumina, silicon carbide, and zirconia. 5 . A three-dimensional shaped article production apparatus for producing a three-dimensional shaped article by forming the stacked body on the forming surface of the shaping stage according to claim 1 . 6 . A three-dimensional shaped article production apparatus for producing a three-dimensional shaped article by forming the stacked body on the forming surface of the shaping stage according to claim 2 . 7 . A three-dimensional shaped article production apparatus for producing a three-dimensional shaped article by forming the stacked body on the forming surface of the shaping stage according to claim 3 . 8 . A three-dimensional shaped article production apparatus for producing a three-dimensional shaped article by forming the stacked body on the forming surface of the shaping stage according to claim 4 . 9 . A three-dimensional shaped article production method, comprising: forming a stacked body on the forming surface of the shaping stage according to claim 1 ; and applying energy to the stacked body to decompose the organic film. 10 . A three-dimensional shaped article production method, comprising: forming a stacked body on the forming surface of the shaping stage according to claim 2 ; and applying energy to the stacked body to decompose the organic film. 11 . A three-dimensional shaped article production method, comprising: forming a stacked body on the forming surface of the shaping stage according to claim 3 ; and applying energy to the stacked body to decompose the organic film. 12 . A three-dimensional shaped article production method, comprising: forming a stacked body on the forming surface of the shaping stage according to claim 4 ; and applying energy to the stacked body to decompose the organic film. 13 . The three-dimensional shaped article production method according to claim 9 , wherein forming the organic film on the forming surface is performed before the forming of the stacked body. 14 . The three-dimensional shaped article production method according to claim 9 , wherein sintering or melting the constituent material is performed after the applying the energy.
