Rapid Prototyping (RP) System has become an essential tool in the designing and prototyping phases of product development by virtue of its remarkable technological progress. Among other things, moldings made by the powder laser sintering RP system can be used for actual products in terms of mechanical properties and time-tested stability, as well as fewer manufacturing constraints as compared with the conventional methods will enable design-driven product designs. This paper provides the latest information concerning application of the RP system to manufacturing of actual products.
