Using biological materials, robotisits at Cornell University in the U.S have developed the first prosthetic ear from silicone materials using a 3D printer. It is hopeful that this is the first step in developing functional body parts by engineering three dimensional tissue constructs, instrumental in aiding in reconstructive medicine. The system works by collecting the dimensions and distribution of healthy human tissue through MRI scanning, which is then stored, to then be utilised in the development of body parts should they ever be injured. A gantry system is integrated in the printer with the ability to deposit materials precicely within the 3D space to ensure intricasy in design. It is predicted that the technology will be fully developed an utilised within the next two decades.
