DMLS

The ultimate in speed and precision for metal 3D printing, Direct Metal Laser Sintering (DMLS), also known as SLM (Selective Laser Melting), additively manufactures 99% dense metal prototypes and end-use parts. Producing fine featured parts with the strength and durability comparable to forged parts, the DMLS process is ideal for functional components requiring fast lead times and a design freedom that you do not get with traditional machining.

In this process, dual 400-watt lasers micro-weld alloy powders at 30 micron layers as a bi-directional recoater blade deposits the next layer of alloy powder. With the unique dual laser features, this technology builds robust, metal prototypes and end-use parts with remarkably accurate features.
