| Abstract: | As the most potential and advanced technology, 3D printing of metal parts has became more and more popular in manufacturing industry. Selective laser melting (SLM) is a crucial branch of metallic 3D printing. With great advantage of process in complex and abnormal shape parts, which can not be fabricated with traditional methods, SLM is able to solve the remaining technical problems such as long production cycle, high cost and difficult processing. This research aims to summarize and analysis the fundamental principles, equipment, material characteristics and processing parameters of SLM. Porosity, balling and stress occurred in SLM are also discussed, and the research prospect of metallic 3D printing is introduced in the end. |
