How do you build on mars? 3d printing from dust!
Let's say we get to Mars. Or ever decide to go back to the moon. It'll be far better to build everything we need using the resources available on location, rather than adding materials to the payload of the craft carrying us there.
The European Space Agency identified this in 2013, when it unveiled its plans for a 3D printed moon base, and architects have proposed 3D printing on Mars, too. And now we know it's possible, thanks to Northwestern University's Ramille Shah and her Tissue Engineering and Additive Manufacturing Laboratory.
