DMLS Technology for 3D Printing

DMLS: Laser Powder Bed Fusion of metal powder in a 3D printer

With DMLS it is possible to create 3D printed metal parts directly from a computer model. The main ingredient to create such a part is a powder of a metal alloy. The technology is used for industrial 3D printing.

In the metal 3D printer, an ultra-fine layer of the metal powder is spread across the building platform. Then, a powerful laser in the 3D printer melts the powder exactly at the points defined by the CAD model. In this way, one layer of the 3D printed part is completed. This procedure repeats until the part is completed: 

Three steps of the DMLS technology

1. The 3D printer continues to spread layer by layer of the metal material
2. The laser precisely melts the desired shape in each layer 
3. The 3D printed part grows layer by layer.

The DMLS technology, as used by EOS metal 3D printers, follows the principle of - in German - "Direkt Metall Laser Schmelzen" (DMLS, Englisch translation Direct Metal Laser Melting). It is a Laser Powder Bed Fusion, or short LPBF technology, and stands for one of the world's most advanced and reliable technologies in metal additive manufacturing. This high-end 3D printing technology is used for serial manufacturing of (industrial) 3D printed metal parts for a wide range of industries. The main applications are aerospace, automotive, medical, tool and turbomachinery. EOS is the leading global provider for industrial metal 3D printer and has been using the DMLS technology for almost three decades.

The use of titanium as the material for the retaining brackets of our satellites has proven highly effective. The main weakness, however, was the connection of the brackets with the carbon panel of feed and reflector assembly because here the thermal stress was a negative factor. Thanks to Additive Manufacturing, we were able to redesign the bracket and eliminate this vulnerability. There were other benefits, too, such as shorter, more cost-effective and more lightweight production.
