3D printing could bring space travel into a new era
"The promise is enormous, You can make very complicated parts without one screw," says Director of technology at the ESA, Franco Ongaro, "...in terms of time, in terms of mass, in terms of ability to do things we can only dream of"
The international space station already has a 3D printer which can create plastic items but in the short term the ESA aims to develop the technology to produce engine parts for Rocket launchers or complex structures to install on planets and moons
