摘要
PROBLEM TO BE SOLVED: To provide a microsphere having excellent slidability or fluidity, also capable of attaining a high packing ratio, and suitable for use in selective laser sintering.;SOLUTION: The microsphere includes a thermoplastic resin, has a mean particle diameter of 1 to 100 μm, has an almost spherical shape, and used for selective laser sintering. The almost spherical shape denotes the ones in which the circularity of each particulate is ≥0.7, and the circularity is a value obtained, regarding a plurality of particles, by finding the ratio (the projected area of each particle/the area of a circle with the maximum length of each particle as the diameter), and arithmetically averaging them, and a part or the whole of the surface of the microsphere is coated with flocculation preventive particles.;COPYRIGHT: (C)2007,JPO&INPIT
