3-D food printers are looking at providing powdered forms of ingredients, and these would not be processed ahead," says Douglas. Pizza is one of the comfort foods unavailable to astronauts on current missions. And since the 3-D printer does most of the work, astronauts wouldn’t have to deal with extensive food prep.

NASA said the proposal is intriguing in part because it could save weight on a spacecraft, and because such technology could be used to make other objects, such as tools.
