A method for manufacturing a metal shaped article by bonding particles of metal powder contained in a powder layer to each other includes: forming a powder layer by leveling, with a squeegee roller, metal powder that has an average circularity of 0.80 or more and less than 1.00, a specific surface area of 0.30 m2/g or less, a particle diameter D50, at which the cumulative frequency from the small diameter side is 50% in a cumulative particle size distribution, of 1.0 μm or more and 10.0 μm or less, and a particle diameter D90, at which the cumulative frequency from the small diameter side is in the cumulative particle size distribution, of 11.0 μm or more and 25.0 μm or less; and bonding the particles of the powder contained in the powder layer to each other; wherein the rotation speed of the squeegee roller is set to 0 rpm or more and 50 rpm or less, and the moving speed of the squeegee roller is set to 1 mm/s or more and 25 mm/s or less.
A method for manufacturing a metal shaped article by bonding particles of metal powder contained in a powder layer to each other, the method comprising:
A metal shaped article shaped by stacking a molten material or a sintered body of the particles with each other in a stacking direction in a powder layer containing metal powder, wherein
