Coated Metal Powder Selective Laser Sintering Rapid Prototyping Technology Research

Rapid prototyping technology is a big break through in province of manufacture in twenty years. The paper present the principle of Selective Laser Sintering, development in home and oversea and it's application in the metal molds. The technics of the Selective Laser Sintering for metal power covered with organic resin is studied in this paper, the content of research include three segments, firstly, we have finished the manufacture of 316L stainless steel metal power cocered with organic resin, the metal power covered with organic resin is applied by a lot of department and effect of use is very good, this technology also acquired patent. Secondly, the technics of Selective Laser Sintering is also studied in this paper, we have received the best technological parameter through the experiment and analysis. The last, we have accomplished the last treatment to the parts, on account of the parts have excellent mechanical capability, it can satisfied the damand of metal molds.
