Taxonomy on the production processes and characterization of powder metallurgy used in additive manufacturing process

Purpose. This article presents a concise and comprehensive review of the technologies that are typically used for manufacturing metal powders as well as the implications that particle features have on the properties of additive manufacturing (AM) techniques. Methodology. We surveyed various experiments that have taken place on the effects of the qualities of the powder and how to guarantee the dependability and reproducibility of the parts that are manufactured as well as ways of optimizing a powders performance. We classified the methods for producing metallic powders and highlighted the benefits, limitations, and image analysis of major production techniques. Findings. The usage of different approaches to metallic powder characterization for the analysis of the physical, mechanical, and chemical processes has contributed to major steps in powder optimization. The characterization of these powders is critical for ensuring adequate additive material dimensions and specifications and recording the properties of powders used in an AM and bridging the gap of comprehension concerning the end output in AM. Originality. This paper provides a thorough analysis of the efforts made in the powder characterization of AM components for the interpretation of the impact on the part materials qualities and characteristics. Metallic powder characterization has contributed to substantial progress toward powder optimization in the analysis of particle structures. Practical value. As the application of AM technology is moving away from the creation of prototypes and toward the production of finished products, it becomes important to understand the powder properties necessary to manufacture high-quality elements consistently.
