It looks like bone. It feels like bone. For the most part, it acts like bone. And it came off an inkjet printer. Washington State University researchers have used a 3-D printer to create a bone-like material and structure that can be used in orthopedic procedures, dental work and to deliver medicine for treating osteoporosis. Paired with actual bone, it acts as a scaffold for new bone to grow on and ultimately dissolves with no apparent ill effects.
