Direct Metal Laser Sintering (DMLS) has been used for manufacturing prototypes, functional metal components and prototype tools for more than 10 years. During this period the technology has advanced to a level where direct production of complex metallic parts for various applications is everyday life and manufacturing with its various challenges is its main target. The shift from prototyping to production requires changes in the technology and also in the organizations taking part in the shift. This paper presents the latest status of the DMLS technology and materials development trends for different application areas using EOSINT M270 laser sintering machine. Commercially launched materials include presently biomedical materials like Titanium and Cobalt Chrome alloys, ultra high strength Maraging Steel alloy, Stainless Steels and other high-end engineering materials. In addition, there are many materials which have been developed for evaluation purposes, waiting for industrial applications.
