From Prototyping to Production Using Laser Powder Bed Fusion

The ultimate in speed and precision for metal 3D printing, Metal Laser Sintering — which includes Direct Metal Laser Sintering (DMLS), also known as SLM (Selective Laser Melting) — additively manufactures 99 percent dense metal prototypes and end-use parts.

Producing fine featured parts with the strength and durability comparable to forged parts, the Metal Laser Sintering process is ideal for functional components requiring fast lead times and a design freedom that don't exist with traditional machining.

In this process, dual 400-watt lasers micro-weld alloy powders at 30 micron layers as a bidirectional 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.
