3D printing is reshaping the way we think about manufacturing and prototyping, and now NASA is using a version of the technique to build the next generation of rockets. The process, known as "selective laser melting," uses layers of metal powder traced in specific patterns by a laser. The powder welds together at the point of contact, and the process is then repeated in layers, building up a physical object in the same way traditional 3D printing works.
