If I lived on a space station I'd feel much safer with a 3D printer on board. I think it's brilliant that NASA will launch one into space in 2014. The idea is that if anything breaks, astronauts will be able to manufacture their own spare parts and fix the problem straight away. The 1970s crew of Apollo 13 had a tough time making a filter out of a plastic bag and gaffer tape… With today's new technologies they could have reached the Moon.
How else can 3D printing improve our lives? Come and check out the new Antenna exhibition 3D: printing the future, at the Science Museum from 9 October 2013.
