LMD: A New, Less Wasteful Metal 3D Printing Technique Meltio's Wire-Laser Metal Deposition 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 be followed to prevent the loose spread of powd...
