"If you shatter a bone in the future, a 3D printer and some special ink could be your best medicine. Researchers have created what they call “hyperelastic bone” that can be manufactured on demand and works almost as well as the real thing, at least in monkeys and rats. Though not ready to be implanted in humans, bioengineers are optimistic that the material could be a much-needed leap forward in quickly mending injuries ranging from bones wracked by cancer to broken skulls.
“This is a neat way to overcome the challenges we face in generating bone replacements,” says Jos Malda, a biomaterials engineer from Utrecht University in the Netherlands who was not involved in the work. “The scaffold is simpler to make than others and it offers more benefits.”"
