A polyarylene sulfide resin particulate has a mean particle diameter from more than 1 &#x3bc;m to 100 the uniformity is 4 or less, the melt viscosity measured at temperature of 300&#xb0; C. and shear rate of 1216 secis 150 to 500 Pa&#xb7;s, and the recrystallization temperature, defined as temperature of the heat generation peak at the time of crystallization when cooled from 340&#xb0; C. to 50&#xb0; C. at 20&#xb0; C./min using a differential scanning calorimeter, is 150 to 210&#xb0; 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.

Polyarylene sulfide resin particulate and method of producing same

A method of producing polybutylene terephthalate resin shaped moldings includes supplying a 3D printer with a polybutylene terephthalate resin powder mixture that contains 100 parts by weight of a polybutylene terephthalate resin powder material having a mean diameter of more than 1 &#x3bc;m and 100 &#x3bc;m or less, a uniformity coefficient of 4 or less, and a terminal carboxyl group quantity of 35 eq/t or more and 50 eq/t or less, and 0.1 to 5 parts by weight of inorganic particles having a mean diameter of 20 to 500 nm.
