In China, doctors have successfully 3D printed a model of a 9-year-old little girl's left ear (mirror image) in order to create a new right hear for her. The little girl was born with a birth defect that caused her to have a deformed right ear. Using a 3D printed model, surgeons were able to sculpt a new ear for the girl using cartilage from her ribs. The ear was then implanted under her skin where it will grow for a full year, before being brought to the surface. Read and see more on this at http://3dprint.com/87296/3d-printed-ear-little-girl/
