LMD: A new, less wasteful metal 3D printing technique
Metal 3D printing is currently dominated by powder-based techniques like SLM (Selective Laser Melting). These processes yield incredibly precise parts, but the build times are slow. Furthermore, dealing with the powder increases manufacturing complexity: Whenever the powder is transported, loaded into the machine, or cleaned up afterwards, rigorous steps must
A Spain-based company called Meltio has developed a new metal 3D printing technology that does away with powder-based hassles. The wire is fed into a point where three to six low-power diode lasers converge, creating what's known as a "melt pool." Or a part could be printed with a combination of corrosive and anti-corrosive metals, for instance if one face will be exposed to the elements.
