Another CNC related technology is 3D Printing and this seems on its way to change a lot in a near future. One example: I just heard about ways to use 3D Printing to "grow a backup heart" for a person! By Tomography/CATscan a three dimensional blue-print of the organ is created and loaded into a 3D printer and then a copy of the heart is created. Then cells from the person are DNA modified into "believing they are heart-to-become cells" and applied to start growing on the 3D modelled heart. The point here is that the 3D printed heart clone is built from a material that disappears when "colonised" by organic cells.
