A Review on Mechanical and Corrosion Behaviour of DMLS Materials

Abstract

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 Computer-Aided Design (CAD) file in stack manner 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 are analyzed, and the effects of post-processes on the material properties are discussed. The objective of the paper is to consolidate previous research efforts 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.
