4D printed hydrogel leaf brings University of Alberta researchers one step closer to bioprinting organs

A team of scientists from the University of Alberta’s Ingenuity Lab in Canada have used 3D printing to create a leaf structure made from natural proteins and a printable hydrogel material. The project, says the team, brings them one step closer to creating an implantable 3D bioprinted organ.
