NASA and 3D printing Sky-rocketing, Economist
"Aerospace was one of the first industries to take up three-dimensional (3D) printing. This is because 3D printers are good at making things which are complex and lightweight. ... So far, 3D-printed aerospace parts tend to be used in non-critical areas, such as brackets or ducts. Now NASA has shown that the technology is capable of a far more demanding role: making rocket engines."
