A great advance:
“Now, Ramille Shah at Northwestern University in Evanston, Illinois, and her colleagues have developed an ink that can be 3D-printed into bone implants that are robust but ultra-elastic, allowing surgeons to cut and manipulate them in the operating theatre to form the perfect shape.
Once in place, the implants are rapidly infiltrated by blood vessels and gradually turn into natural bone. Shah’s team calls the implant material “hyperelastic bone” and says it could heal a multitude of skeletal problems, from fractures and spine repairs to implants that help to rebuild faces after injury or chemotherapy.”
