Abstract

Metal Additive Manufacturing (Metal AM) technology is rapidly developing with many unique ideas. Among them, the method of using lasers or electron beams to melt a layer of metal powder (Powder Bed Fusion – PBF) is widely applied due to the high precision of the resulting product and the superior mechanical properties compared to other processing methods. This paper analyzes research on 3D printing technology of metal materials worldwide, examines its practical application in domestic research and training, and proposes a design model for a laboratory-scale Selective Laser Melting (SLM) 3D printing system that is cost-effective, safe, and suitable for localization. The research shows that designing and manufacturing a small-scale SLM system is feasible and highly valuable for training, materials research, and mechanical processing at universities, academies, and research institutes in Vietnam.
