Bioprinting human tissue has evolved to 3D printing of human body parts. Doctors are practicing surgeries on printed replicas of human organs, while radiotherapists are enacting cancer treatments on printed heads made from material that reacts to radiation rays like human tissue.

If 3D organ printing can jump through government hoops, it may become routine for surgeons to prepare for complicated surgeries like emergency transplants and tumor removals using exact replicas of patient organs. Additionally organ shortages may be a thing of the past.
