Selective Laser Melting (SLM) is an additive metals manufacturing technology with a growing presence in the healthcare, aerospace and high technology engineering and electronics sectors.

The SLM process uses a high powered laser to fuse fine metal powders together layer by layer direct from CAD data to create functional metal parts. After each layer a powder re-coater system deposits a fresh layer of powder in thicknesses ranging from 20 to 100 microns. The SLM system uses commercially available gas atomized metallic powders to produce fully dense metal parts in materials including Titanium, Stainless Steel, Cobalt Chrome and Tool Steel.

The process works by using a laser to melt fine layers of gas atomised metallic powders together directly from a CAD model building up the part one layer at a time, similar to that of SLA. The powder is applied in very thin layers between 20 to 100 microns so the parts can have excellent detail, strength and finish.

The downside is minor pitting on verticle surfaces.

The type of printing is a form of fused deposition. See one in action in this video:

One of the more controvertial uses for this technology is the unregulated fabrication of amunition and arms.
