Additive Manufacturing Powder And Additively Manufactured Body

Abstract

An additive manufacturing powder used for manufacturing an additively manufactured body is provided: in which a particle diameter D50, at which the cumulative frequency is 50% from the small diameter side, in a cumulative particle size distribution on a volume basis obtained by using a laser diffraction type particle size distribution measuring apparatus, is 1.0 μm or more and 10.0 μm or less; a particle diameter D90, at which the cumulative frequency is 90% from the small diameter side, in the cumulative particle size distribution, is 11.0 μm or more and 25.0 μm or less; a specific surface area is 0.30 m2/g or less; a number ratio of particles having a circularity of 0.750 or more and 0.950 or less is 70.0% or more; and a coefficient of variation of circularity of particles, obtained by dividing a standard deviation of circularity of the particles by the average circularity, is 15.0% or less.
