Abstract
A resin powder for three-dimensional molding includes ethylene-propylene copolymer particles. The volume average particle size of the ethylene-propylene copolymer particles is within a range of 5 to 200 μm. The ethylene content molar ratio (ethylene/(ethylene+propylene)) in the ethylene-propylene copolymer particles is within a range of 0.001 to 0.04. The melt flow rate (MFR) is within a range of 3 to 40 g/10 min at 230° C.
