NASA Using 3D-Printed Parts to Test Model of World's Largest Rocket

Engineers at NASA's Marshall Space Flight Center are using 3D printing to make parts for a scale model of NASA's new rocket, the Space Launch System (SLS). To make the parts, the engineers used selective laser melting. The model is being used for acoustic testing, which will show how the powerful noise generated by the engines and boosters may affect the rocket and crew, especially during liftoff. The data will then be used to verify the design of the rocket's sound suppression system.
