摘要 |
PROBLEM TO BE SOLVED: To provide a powder material for three-dimensional molding, which can reduce uneven strength of a three-dimensional molded object and can give a three-dimensional molded object having uniform strength.SOLUTION: The powder material for three-dimensional molding comprises a base material coated with a resin, in which an aspect ratio of the powder material calculated by numerical formula 1: (aspect ration (average))=X1*Y1/100+X2*Y2/100+...+Xn*Yn/100 is 0.90 or more, and a coverage of the resin is 15% or more. In the formula, Xn represents an aspect ratio (minor diameter/major diameter); Yn represents an abundance (%) of particles having an aspect ratio of Xn; and n is 15,000 or more.SELECTED DRAWING: None |
