Direct Metal laser Sintering technique (DMLST) is one of the technologies which is generally used to built prototypes and tooling applications. DMLST uses powder bed fusion to bond particles together by laser energy. A new powder layer is spread on top of the previous layers and the process is repeated up to required shape of part can be produced. This review paper presents development, current status and challenges of the DMLST with emphasises on material processed by DMLST and is aimed to understand influence of density, microstructure, micro-hardness, tensile strength and wear behaviour of built-up parts. It also highlights the process through proofs based on classical results in terms of advantages and applications. |
