Status and Progress of Selective Laser Melting Forming Technology

Selective Laser Melting (SLM) was a novel method of Rapid Prototyping (RP). The benefits of SLM: simple process, good surface roughness, high-precision molding size, density of almost 100%.The basic principles of the technique, the major problems and present situation in China and abroad were described and introduced. And discuss the development trend of the SLM technology.
