Check out the Meltio M600, available at MatterHackers.
Most metal 3D printing means powder, which means a sealed chamber, inert gas, and handling protocols for a material that is reactive and behaves like flour under the wrong conditions. The M600 uses wire instead. Standard welding wire feeds into a melt pool created by nine blue diode lasers, 1000W total, depositing dense metal layer by layer with no powder anywhere in the process.
The wavelength is the interesting part. Copper and aluminum reflect most of the infrared light that conventional fiber lasers use, which is exactly why those metals are difficult on many systems. At 450nm they absorb far more of that energy, so the M600 runs stainless, mild and carbon steels, titanium alloys, nickel alloys, copper, and aluminum on the same machine. Build volume is 300 x 400 x 600mm, it ships pre-calibrated, and closed-loop process control with an integrated 3-axis touch probe holds deposition consistent across long builds. Optional hot wire and dual or quad-wire upgrades add throughput and multi-material capability.
