Abstract
A laser-sinterable resin powder, which retains properties of styrene resins such as impact resistance and low water absorption and shows sharp decrease of melt viscosity similarly to crystalline resins at a temperature not lower than the glass transition temperature can be made of a thermoplastic resin composition containing 10-80 mass % of a crystalline resin (A) with a melting point of 80-250° C. and 20-90 mass % of a styrene resin (B), and having a 50% average particle diameter of 10-100 μm. The Component (A) is preferably a polyolefin resin. The Component (B) is preferably a rubber-reinforced styrene resin composition, wherein the rubber component is preferably an ethylene-α-olefin copolymer rubber and/or a hydrogenated product of a diene rubber. The laser-sinterable powder preferably has a melt flow rate of 5-500 g/10 min.
