Original Abstract Submitted
An additive manufacturing powder includes an Fe-based metal material and is used to manufacture an additively manufactured object that is to be turned into a metal sintered object by sintering. The additive manufacturing powder has a particle size D50 of 1.0 μm or greater and less than 15.0 μm, and a particle size difference D90-D10 between a particle size D90 and a particle size D10 of from 5.0 μm to 18.0 μm, where, in a volume-based cumulative particle size distribution curve, D10 is the particle size at which the cumulative volume of particles reaches 10% as counted from the smaller side, D50 is the particle size at which the cumulative volume of the particles reaches 50% as counted from the smaller side, and D90 is the particle size at which the cumulative volume of the particles reaches 90% as counted from the smaller side. The additive manufacturing powder also has a specific surface area of from 0.05 [m/g] to 0.25 [m/g], and a water content of 200 ppm or less as measured by the Karl Fischer method at 250° C. An average circularity of the particles is from 0.85 to 0.99.
