A new technology for 3-D-printing metal parts could be a cheaper and more versatile alternative to common industrial metalworking techniques. It also opens the door to new kinds of parts with unique properties that arise from the precise combination of multiple metals. Possible applications include structural parts for things like car or airplane bodies, as well as components of engines, electrical devices, or other machines.
That’s according to AJ Perez, CEO of NVBOTS, the Boston-based startup that developed the new method. The company says the technology, which is capable of printing 21 different metals from aluminum, nickel, and tin to alloys like stainless steel and nickel titanium, is the only one that can use multiple metals during the same job.
