Direct Metal Laser Sintering
Fast, precise, modern & ultra-responsive
Direct Metal Laser Sintering (DMLS) is the most widely used additive manufacturing (formerly Rapid Prototyping) technology used for metal layer-manufacturing parts. Its growth has been driven by the broad acceptance of additive manufacturing, which began with plastic-based materials in the 1980s, and the many commercially available DMLS 3D printing materials.
DMLS parts are made from 3D Cad data in hours or days and eliminate the need for expensive tooling.
EOS is the leading machine manufacturer of DMLS, but machines are also manufactured by SLM, Concept Laser and Renishaw. Like EOS, all three companies are based in Europe.
Another common name for DMLS is laser sintering. DMLS parts are made by a laser systematically melting or sintering a 20 or 30 micron thin layer of powdered metal on to another layer. Once a layer is finished, the sintered part descends into the powder bed. A recoater arm then passes over the freshly deposited powder before the laser begins to sinter the next layer.
The process is repeated until the part is fully produced. Manufactured parts possess the same mechanical properties as wrought or billet, and can be finished using a variety of traditional post processes.
