Resin powder mixture, method for producing same, and method for producing three-dimensionally shaped article

A resin powder mixture containing a polyarylene sulfide resin powder having a generated gas amount of 0.25 wt% or less, a melt flow rate of 5-75 g/10 minutes inclusive, and an average particle diameter of 1-100 [mu] m inclusive; a method for producing the resin powder mixture; and a method for producing a three-dimensional molded article using the resin powder mixture. By using the resin powder mixture of the present invention, a three-dimensional molded article having few voids and excellent tensile strength can be obtained. 包含产生气体量为0.25wt％以下、熔体流动速率为5g/10分钟以上且75g/10分钟以下、平均粒径为1μm以上且100μm以下的聚芳撑硫醚树脂粉末的树脂粉末混合物及其制造方法、以及使用了该树脂粉末混合物的三维造型物的制造方法。通过使用本发明的树脂粉末混合物，从而可以获得空隙少、抗拉强度优异的三维造型物。
