1. Using high-power laser (1000w above) scan in the sintered metal powder snow, layer by layer stack molding, molding pieces to perform the post-processing through surface molds, production molds work extremely well as die-casting drops dead, forging dies used.
2. Potomac the business in 1998 in addition to 1999, respectively, released the LENS-50, LENS-1500 versions of steel metal, iron-nickel alloys, titanium, nickel alloys, titanium, tantalum and nickel-aluminum alloy because the raw material, the employment of laser technology, molten shiny directly deposition modeling, the production regarding metal parts strength in the traditional method regarding production of shiny parts, precision in the by plane of around 0. 13mm, uncle’s direction of 0. 4mm, even so the high surface roughness, the equivalent level of mud casting surface complete, before use trying to find finishing.
3. China has released this year's research work within this area, Northwestern Polytechnic School, Beijing University of Aeronautics made by this method higher temperature alloy segments, Tsinghai University is additionally carrying out this specific work. Hashing University of Science in the international level, any laser - Plasma blend molding technology, namely the employment of high-power laser sintering shedding metal powder layer by layer, layer by layer using plasma profile shaping in the entity to obtain high surface accurate metal parts as well as Die.

Rapid Prototyping: the idea combines the numerical control technology, CAD technologies, laser technology, products science and technologies, automatic control technology and various advanced achievements in the discipline, the by using light, heat and various energy forms, products, sintering, curing, bonding or shedding eventually forming a component of the three-dimensional bodily model
