摘　　要：球形金属粉末是金属3D打印的核心原料,关系到3D打印技术的发展。目前3D打印球形金属粉末主要由外国厂家垄断市场,国内生产的球形粉末存在性能不稳定、成本高、产量低等问题。本文对3D打印用金属粉末主要制备工艺的基本原理进行了阐述,并分析了各自优缺点,并提出建设性建议。The spherical metal powder is the core material of metal 3D printing,which is related to the development of 3D printing technology. At present,the spherical metal powder for 3D printing is mainly monopolized by foreign manufacturers; the spherical metal powder produced by domestic manufacturers has the problems,such as unstable performance,high cost,low yield,and so on. The ultimate principle of main preparation technology of metal powder production for 3D printing is stated,which advantages and disadvantages are analyzed, and the constructive suggestions are proposed.
