Claim 0:
1. 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 body that comprises a first portion which has a plurality of pores through a height of the three-dimensionally shaped body, and a second portion which does not have the pores or has a plurality of the pores sealed, wherein the second portion is surrounded by the first portion;
a stage, on which the three-dimensionally shaped body is placed; and
a suction unit for adsorbing the three-dimensionally shaped body onto the stage by suction,
wherein the stage is provided with pores penetrating through the stage in a thickness direction and the suction unit is configured to adsorb the three-dimensionally shaped body onto the stage by sucking through the pores provided in the stage, and
wherein the stage is provided with pores penetrating through the stage in the thickness direction to form pore openings on a top surface and a bottom surface of the stage, the suction unit being configured to absorb the three-dimensionally shaped body onto the stage by sucking through the pore openings of the pores in the bottom surface of the stage,
a pore width of the pores provided in the stage is larger than a pore width of the pores provided in the first portion.
