EOS offers the EOS M 290 Direct Metal Laser-Sintering (DMLS™) system for tool-free production of serial metal components, spare parts, and prototypes. Build volume is 9.8 by 9.8 by 12.8 in.
The unit offers extensive monitoring functions for the system and for the build process. A camera built into the process chamber monitors the powder bed, following powder deposition and exposure, by means of still images. Parameters including the position of the Z axis or scanner, laser power, air humidity, temperature, and pressure are monitored continuously.
The system, equipped with a 400-W laser, can be operated under an inert (nitrogen) atmosphere or under argon, which allows processing of light alloys, stainless and tool-grade steels, and superalloys.
Users can develop their own parameters for specific applications on the basis of the EOS parameter sets. These include laser power and exposure speed or strategy.
