摘要：

Metal additive manufacturing (AM) has received a lot of attention since its introduction, owing to its cost efficiency and freedom in design. For a successful and repeatable AM process, metal powders conform to strict chemical and physical properties requirements. There are numerous factors affecting these characteristics in both virgin and used powders. This article presents a comprehensive overview on manufacturing methods of AM metal powders and the reusability of titanium, nickel and aluminum alloys (mainly Ti-6Al-4V, nickel alloy 718 and AlSi10-Mg) as well as criteria for such reuse. Moreover, the feasibility of recycling AM metal powders is discussed. This article also provides perspectives and recommendations for AM users to develop a well-defined and standard powder reuse process for consistent powder characteristics and built parts.
