EOS M 290

The EOS M 290 series is the most widely adopted family of DMLS (Direct Metal Laser Sintering) systems in the EOS range, designed for the industrial additive manufacturing of metal components. All models share a 250 x 250 x 325 mm build volume and an Yb-fiber laser with scanning speeds of up to 7.0 m/s. The base M 290 uses a single 400 W laser with a spot of about 100 µm; the M 290-2 pairs two 400 W lasers that expose the powder bed simultaneously to cut build times; the M 290 1kW raises power to 1000 W with a spot of about 90 µm, ideal for highly conductive and reflective materials.

Layer thickness is adjustable between 20 and 80 µm depending on the material. The material portfolio is one of the broadest in the industry and includes aluminium alloys, stainless steels, titanium and nickel alloys, cobalt-chrome, maraging steel, tool steels and copper alloys. In series production since 2014, the series is prized for repeatable part properties from job to job and machine to machine.

Typical applications range from aerospace and medical to the series production of metal components, with the 1kW variant dedicated to heat exchangers, inductors and high-conductivity electrical parts.
