With the popularity of the 3D printer on the rise, there was just bound to be someone to think, “Why use plastics that can snap? Why not just use metal?”
Well, here it is, the metal 3D printer! While huge industrial metal 3D printers have been used for around 3 years now, Matterfab, a metal 3D printing startup, has recently developed a cheaper and smaller version. Unlike the conventional 3D printer which extrudes out plastic filament, the metal printer works by laying down metal powder on a build plate, then melting layer upon layer onto the piece with a laser.
You can trust the durability of these metal 3D printed parts; GE has been using these parts for their new engines, due out in 2016.
