3D printing in space

The European Space Agency sent along a 3D printer to the International Space Station, and recently, it was used to create a 3D metal object. As you might expect, in micro gravity, it took a while to calibrate the machines.

But the result is that they now can now print a part that they need for a repair on the station - and it naturally has implications beyond the ISS.  As we move further from Earth, we have to be prepared for many eventualities.  And a 3D printer allows for a wide range of possibilities.

Remember that in Apollo 13, they had to repurpose whatever things they could find on board to ensure that the astronauts could return home.  Imagine how that could have gone if they could have made literally anything out of an idea.
