We won’t be surprised if the time comes when we can print just about anything, says Yahoo! News. Even today 3D printing is advanced enough to create toys, a fully-operational car, and even teeth and blood vessels. Now, researchers from the Washington State University have come up with a technique to make new bones using a commercially-available 3D printer they optimized for the study. The repurposed printer sprays a plastic binder over a bed of bone-like calcium phosphate powder with silicon and zinc additives that double the strength of the man-made bone. This results in a sheet half a hair thin, so the process is repeated over and over again, building up layers of the ultra-thin sheet to create the structure.
