Big Printer

"GE Plans World's Largest Laser-Powered 3D Printer":

The prototype Atlas printer, announced on Wednesday, can print objects up to one meter long using titanium, aluminum, and other metals instead of the plastics, resins, and filaments that many commercial and consumer 3D printers use. That means it could print an entire engine block for a car or truck, for example, replacing the specialized machines and tooling that are currently required to make those types of products in a factory.
