摘要：

PROBLEM TO BE SOLVED: To provide composite material powder for selective laser sintering, which can improve strength of a molding while maintaining moldability (difficulty of occurrence of thermal shrinkage) and recyclability.SOLUTION: Provided is composite powder used for selective laser sintering, comprising: spherical aggregates having absolute specific gravity of 0.8 to 2.0, an average particle size of 10 to 150 μm, and no melting point; and polyamide 11 having an average particle diameter of 30 to 150 μm. A difference in particle diameter is within ±25%, which is defined by the following formula: difference in particle diameter(%)={(average particle size of spherical aggregates - average particle diameter of polyamide 11)/(average particle diameter of polyamide 11)}×100.
