The Direct Metal Laser Sintering (DMLS) process from EOS is well established for the netshape fabrication of prototype and short series tooling for plastic injection moulding and diecasting. Now, recent developments in the powders coupled with the durability of the materials are extending its reach to the direct manufacturing of functional prototypes for powder metallurgical (PM) and cast components — in the following referred to as rapid manufacturing — as well as tooling for powder injection moulding and other applications. Jouni Hänninen of EOS Finland reviews the development of DMLS and its current and potential applications.
