We've seen 3d printing used to create prosthetic hands and arms for kids, but now doctors in London are using the technology to create a prosthetic nose for a little girl named Tessa. Tessa was born without a nose -- a very rare condition only reported 47 times in medical history. Doctors used a 3D printed model of her skull to create a molded nose that could be implanted under the skin. Tessa will have many more surgeries in the coming ears to gradually build up the new nose. All of this is made possible thanks to 3d printing technology. Read and see more at http://3dprint.com/70437/3d-printed-nose-little-girl/
