EOSINT M 280

The EOSINT M 280 is the newest addition at GPI and our second machine from EOS. The EOSINT M 280 is an updated and improved version of the EOSINT M 270, an additive layer manufacturing system for metal components. It builds high quality metal parts from 3D CAD data fully automatically, with no need for tools.  The system builds parts up layer by layer by melting fine metal powder with a laser, enabling the creation of extremely complex geometries.  Parts can be made that wouldn't be possible with CNC machining, including deep groves and three-dimensional cooling channels.

The system is equipped with a solid state 200 watt laser which provides exceptionally high quality parts during the building process. The system operates in both protective nitrogen and argon atmospheres, allowing a wide range of materials to be used including: light metals, stainless steel, tooling steel and super alloys. The EOSINT M 280 offers a number of powdered metal materials with corresponding parameter sets and standardized property profiles. In addition, all materials are subjected to an intensive process development procedure and constant quality assurance.
