NASA's 3D-printed rocket pump passes brutal stress test
NASA is pushing the state-of-the-art for 3D additive printing and wants to bring US industry along with it. It recently tested a rocket engine's crucial turbopump unit that was built almost entirely of 3D printed parts (see the video below). Marshall Space Center design lead Mart Calvert said that NASA and its private partners are "making big advances in the additive manufacturing arena with this work. Several companies have indicated that the parts for this fuel pump were the most complex they have ever made with 3D printing."
