83-Year-Old Woman Gets the World’s First 3-D Printed Jaw Transplant | Popular Science: “Once the team designed the jaw, it was just a matter of sintering it together, according to LayerWise. A high-precision laser heated titanium powder particles to melt them together in successive layers. It took 33 layers to build just one millimeter, so the whole jaw consists of thousands of layers, BBC reported. Doctors coated the jaw in a biocompatible ceramic layer and attached it to the woman’s face in a four-hour surgery. That’s one-fifth the time it would have taken to perform a reconstructive surgery using the patient’s own mouthparts, BBC said. It weighs 107 grams, which is one-third heavier than her previous jaw, but doctors said she’ll be able to get used to it.”
