The possibilities of a 3D printer are unlimited. From printing your own body, to printing any type of object imaginable, they allow any idea to be put to good practice. The astonishing possibilities of such a device were not yet at hand a few years ago, we discovered them on the way and today we can basically print everything.
Jewelry, clothes, even Iron Man’s arc reactor can be reproduced as easy as saying “mission accomplished”. The right type of 3d printer can make these and many more with the right sort of input and knowledge in the area.
