American Rocket Lab builds world's largest 3D printer
The American company Rocket Lab has built the world's largest 3D printer, which will be used to manufacture reusable space rockets from carbon fiber. The machine, as tall as a 4-story building, weighs 70 tons and is capable of laying down layers at a speed of 100 meters per minute, saving about 150,000 man-hours in the production of new Neutron rockets. It is planned that they can carry up to 13 tons of payload into orbit, with the first launch scheduled for next year.
