Just a few years after launching its Multi Jet Fusion 3D printer, HP is ready to get into the world of 3D metal printing with Metal Jet, a new commercial platform. (Did you expect it to be called anything else?) While the consumer buzz around 3D printing seems to be cooling off, it’s still a useful technology for large scale manufacturing — especially when it comes to metallic components. The usual benefits of 3D printing still apply: It can be both significantly faster and cheaper than traditional methods.
