Abstract
Provided is a powder material for three-dimensional shaping, the powder material including: first resin powder containing homo polypropylene and nanofiber; and second resin powder containing block polypropylene. The nanofiber is, for example, cellulose nanofiber (CNF). The block polypropylene includes, for example, a propylene-olefin copolymer (propylene is excluded from the olefin). The powder material is suitable for manufacturing a polypropylene molded body having excellent balance between impact resistance and flexural properties, by a 3D printer.
