A 3D Printed Satellite
Steve Jurvetson, a venture capitalist and early investor in Tesla, Space X, and Hotmail, printed his own satellite recently. Demonstrating that this is the future of space-living, in other engineers from all over the world have done it too, and there are a few 3D printed satellites in space as we speak.
They can also 3D print spacecraft parts up there, so they don’t have to wait on us down here.
