Ever wanted to 3D print using metal instead of plastic?

Metal 3D printing involves melting layers of metal powders on the order of 20-40 microns. By building layer by layer, you can create a metal part in the same fashion as a 3D printer that uses polymers. These 3D metallic printers are way more expensive than polymer 3D printers, but offer a nice alternative to flimsy polymer parts.
