Abstract

A vacuum-induced multistage atomization process was adopted to fabricate the high-performance 304 stainless steel powder for 3D printing, based on the flexible control of the droplet spheroidization and solidification process. The 36.7 μm-median diameter (D50) 304 stainless steel powder with high sphericity was successfully obtained, together with particle size proportion of 45–55 μm larger than 35% and the lower oxygen and nitrogen content increment below 0.04%.
