摘要: Solid Freeform Fabrication has been used to describe collectively a growing number of toolless manufacturing techniques. One these process Selective Laser Sintering, in which part is generated layers from powder using computer-controlled laser/scanning apparatus and power feed system. An overview the basic principles SLS machine operation given. Two binding mechanisms are described for becomes thermally activated by scanning laser beam: viscous flow melting low-melting-point phase mixed powders differing chemistries
