NASA's 3D-printed rocket part handles 20,000 pounds of thrust in test (video) | Science, Technology, Internet |

Using 3D-printing, NASA has produced a rocket injector plate that can sustain 20,000 pounds of thrust. The original machined injector plate was made up of 115 small parts, whereas the 3d-printed plate is comprised of only 2. Such parts could one day reduce rocket costs while potentially increasing safety, since they're less-complex and have fewer points of failure.
