NASA wants to build huge spacecraft in orbit with robots and 3D printers

Nasa to begin 3D printing in SPACE: An orbiting factory that will build super-sized structures in space is being funded by Nasa. The multi-armed factory will use 3D printing and robotics to create giant space structures, such as antennas and solar arrays, that would otherwise have been impossible to launch from Earth.
