Abstract
A method for producing a three-dimensional shaped article by stacking a plurality of layers is provided, and is characterized in that a series of steps including a layer forming step of forming the layer using a composition containing a plurality of particles, and a joining step of joining the particles contained in the layer to one another by irradiating the layer with a laser beam is repeatedly performed, an average particle diameter of the particles is represented by Dand a thickness of the layer formed in the layer forming step is represented by D, a relation of D/D<5.0 is satisfied, and an arithmetic average height Sa of a surface of the layer in a state where the particles are joined to one another by the joining step is 15 μm or less.
