Three-dimensionally shaped article production apparatus and three-dimensionally shaped article

Abstract

A three-dimensionally shaped article production apparatus is an apparatus for producing a three-dimensionally shaped article by stacking a layer, and includes: a shaping section in which the three-dimensionally shaped article is formed; a layer forming unit which forms the layer using a three-dimensional shaping composition containing particles; and an ejection unit which ejects a binding liquid containing a binding agent for binding the particles onto the layer. The shaping section includes a mask which has an opening with a size corresponding to the size of the three-dimensionally shaped article, and the layer is formed in the opening.
