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 first layer formation step of forming a first layer on a support by supplying a first composition containing first particles and a binder, a second layer formation step of forming a second layer composed of one layer or a plurality of layers on the first layer by supplying a second composition containing second particles and a binder, and a separation step of separating the second layer from the support through the first layer, wherein after the separation step, a sintering step of sintering the second layer is performed.
