The European Space Agency has announced it is hoping to use 3D printing to make working parts for jets, nuclear reactors and even spacecraft.
Experts from across Europe have joined forces and already unveiled a type of printed metal that can withstand temperatures over 3,000C.
David Jarvis, from the Space Agency, said:"Our ultimate aim is to print a satellite in a single piece. One chunk of metal, that doesn't need to be welded or bolted."
Twenty-eight different institutions have come together to make up what's known as the Amaze Project, which is looking for new ways to make metal parts that are stronger than ever.
They say printing metal parts would also reduce the amount of waste and help the space industry become greener.
Amaze have already started printing jet engine parts and aeroplane wing sections up to two meters long.
It might be a while before you can print your own rocket however, as the project is going to cost 20 million euros!
