摘要：
Laser direct metal deposition (LDMD) is a rapid manufacturing technique, dedicated to new part construction or worn part repairing. The process depends on a various range of parameters and the powder characteristics are one of the main crucial parameters. The powder (size,.....) has then a direct impact on an optimized process behavior and the mechanical properties of the manufactured component. This paper focuses on powder investigation, for a better understanding of its influence. The work was performed with different batches of stainless steel AISI316 that have been analyzed and characterized before processing. This paper discusses the results derived from the manufactured samples, highlights the influence of the main powders characteristics and demonstrates the flexibility of the process when the powders meet the specifications.
