▎ 摘　　要

NOVELTY - A stainless steel metal powder comprises 90-99 vol.% stainless steel metal powder base material and 1-10 vol.% reinforcing agent. The reinforcing agent comprises graphene sheets, carbon fibers or carbon nanotubes. The particle size of the stainless steel powder is 1-30 mu m. The graphene sheet has length of 50-500 nm. The carbon fiber has length of 5-20 mu m. The carbon nanotubes have length of 50-1000 nm. USE - Stainless steel metal powder is used for three-dimensional printing. ADVANTAGE - The stainless steel metal powder has narrow particle size distribution, excellent sphericity and fluidity, and can be efficiently prepared. The printed material obtained using the stainless steel metal powder has high quality. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of stainless steel metal powder.
