A Review on Mechanical and Corrosion Behaviour of DMLS Materials

Direct Metal Laser Sintering (DMLS) is an Additive Manufacturing (AM) technique in which the metal powder will be sintered in selected regions as per 3D CAD file in stack manner in order to produce a three dimensional object with less effort, in less possible time and with minimal wastage of metal. In this paper most widely used DMLS metal powders mechanical and corrosion properties were analyzed and the effect of post processes on the material properties were discussed. The objective of the paper is to fuse the works done so far and to identify gaps to identify the key areas of this technology. The promising and successful application of this revolutionary technology in various sectors like biomedical, aerospace and automotive was also discussed based on material behaviour at different operating conditions. This review would help researchers to find challenges in this booming technology. As per the materials point of view future research prospective was suggested in depth in light of present review.
