New development of metal laser additive manufacturing technology

Abstract

Recently, additive manufacturing (AM) technology has been paid great attention in the aerospace, medical and automotive fields because of the possibility of manufacturing high-performance parts. In this paper, the new development of metal laser AM technology, especially the development of powder bed fusion type and deposition type AM machines, the analysis of melting-solidification phenomenon of melt pool, and the development of melting-solidification simulation, structure simulation and thermal deformation simulation are reviewed.
