SLM 125

Accurate, compact and highly performant options for
fast results.

The Selective Laser Melting Machine SLM 125 offers a build envelope of 125 x 125 x 125 mm³. The flexibly applicable machine with high productivity is equipped with a single fiber laser (1 x 400 W) and produces high-quality metal build parts. The precise and economical SLM 125 has been designed for quick results in the research and development sector, as well as for the production of smaller build parts.


Thanks to the machine’s compact design, with few powder-transporting components,
materials can be changed quickly and easily. With a variety of options and expansion
possibilities, the system can be adapted to individual customer requirements.


Reduction Unit

In addition, the SLM 125 provides a build volume reduction of 50 x 50 x 50 mm³, decreasing the powder amount by 80%.

High Quality

Produces high-quality metal build parts using 3D-CAD data. The precise and economical machine is a winning solution, suitable for small lot, as well as in the field of R&D.

Bi-directional powder coater

The machine concept is impressive thanks to its patented process gas filtration and its safety. The adjustable gas flow allows optimal process properties with low gas consumption.

Powder Sieving Machine

During the sieving process the rough particles are sieved out and are separated in an
overflow bottle. The reusable metal powder, which has the defined grain size, is transported to the storage container and can be directly used again.
