Abstract
A polyarylene sulfide resin particulate has a mean particle diameter from more than 1 μm to 100 the uniformity is 4 or less, the melt viscosity measured at temperature of 300° C. and shear rate of 1216 secis 150 to 500 Pa·s, and the recrystallization temperature, defined as temperature of the heat generation peak at the time of crystallization when cooled from 340° C. to 50° C. at 20° C./min using a differential scanning calorimeter, is 150 to 210° C. The polyarylene sulfide resin particulate is suitable as a material powder for producing a three-dimensional molding by a powder sintering three-dimensional printer can be provided efficiently.
