Abstract
Provided is a powder material for three-dimensional shaping which comprises: a resin suitable for three-dimensional shaping with a powder bed fusion type laser-sintering 3D printer, and a cellulose material. The powder material for three-dimensional shaping comprises a powder containing both a resin and a cellulose material, the content of the cellulose material being 2.0-30.0 mass %. In volume-based particle diameters of the particles constituting the powder, the cumulative frequency of particles of 100-300 μm is 30.0% or greater.
