Abstract

A three-dimensional shaped article production method for producing a three-dimensional shaped article by stacking layers to form a stacked body includes a constituent layer formation step of forming a constituent layer which corresponds to a constituent region of the three-dimensional shaped article, a support layer formation step of forming a support layer which is in contact with the constituent layer and supports the constituent layer, and a sintering step of sintering the constituent layer, wherein the support layer is configured such that as compared with the volume decrement accompanying the sintering step of a space surrounded by the constituent layer from at least two directions, the volume decrement accompanying the sintering step of the support layer which supports the constituent layer in the space is larger.
