Zothecula writes: 3D printed tissues and organs have shown real potential in addressing shortages of available donor tissue for people in need of transplants, but having them take root and survive after implantation has proven difficult to achieve. In a positive move for the technology, researchers used a newly-developed 3D printer to produce human-scale muscle structures that matured into functional tissue after being implanted into animals.
