摘　　要：增材制造技术又称3D打印,自提出以来受到国内外学者的广泛关注。金属材料的增材制造相比于其他材料难度较大,对于原材料、工艺控制等方面的要求更严苛。针对国内的增材制造用粉末生产及使用情况,本文从金属粉末粒度分布、形貌和流动性检测方法三个方面,结合实际生产、检测的经验,分别讨论了各种粉末检测方法对于增材制造技术的适用性和可行性。Additive manufacturing technology, also called 3D printing, has been widely concerned at home and abroad since it was put forward. Compared with other 3D printing methods, metal 3D printing has greater difficulties because of the stringent requirements in raw material and deposition process control. Concentrating on the domestic production and usage of the metal powder in additive manufacturing,this paper will discuss a series of test methods in particle size, shape and flowability. The applicability and feasibility of these test methods in additive manufacturing industry will also be elaborated according to the practical industry experience.
