A research team with the University of Alberta in Canada has been working on using the 4D Printing to create 3D Printed Organs for transplant in patients. They are working on 3D Printed resins and believe that the human body would most likely accept a hydrogel organ. The team is currently working on 3D Printing meniscus, or the knee cap that can help surgeons perform surgeries faster and much efficiently.
