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.
GE said it plans to unveil the Atlas in November. The prototype can only print objects up to one meter in two directions, such as length and width, but once the production version is ready next year, it will be able to print objects up to one meter in any direction.
Seems like just the thing for cheap rocket engines.
