NASA seems like they are jumping on board the 3D Printing bandwagon. Scientist for NASA have created satellites which can be printed out by astronauts. This could save a ton of money, as well as make trips to space much safer. If something breaks, the astronauts will be only hours away from printing out a new part. NASA used the example of Apollo 13 to show that 3D printing could have saved a ton of stress and trouble for the Astronauts, had they been able to fix the damaged parts after the explosion they faced.
