EOSINT M 270

The EOSINT M 270 was the first Direct Metal Laser Sintering (DMLS) machine from EOS at GPI. The M270 is 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.  Innovative companies are using this technology for fast, flexible, cost-effective prototypes, series production parts or even spare parts.

DMLS is a well know leading technology for toolmaking.  With its high accuracy and surface quality the system is ideal for building tool inserts.  The freedom of design allowed by this additive manufacturing process allows for conformal cooling channels to be integrated into parts to reduce injection molding cycling times by up to 75%.  This direct process eliminates tool-path generation and multiple machining processes such as EDM.  The process is mainly used for injection molding, however it can also be used for other tooling types including blow moulding, extrusion, die casting, sheet metal forming, etc.

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 a protective nitrogen atmosphere, allowing a wide range of materials to be used ranging from light alloys via steels to super-alloys and composites. The EOSINT M 270 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.
