3D Printing Bone

This is an awesome application for 3D printing and 3D CAD in the medical field. It is crazy to think that with 3D printing and some chemical magic we can create bones from almost nothing. The part of this story that intrigues me most about this is the possible applications and job opportunities that this could bring. as well as the implications to medical field. The ability to grow bones could revolutionize the hip replacement surgery or other such procedures. if 3D CAD can give us the ability to build bones why not hearts lungs and livers.
