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
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.
