It is so possible that 3D printing technology could solve the organ-donor problem in the world. This 3D printed skull using PLA filament is just one of the examples: http://www.3d2print.net/shop/blog/cool/heads-need-new-skull/. This can greatly help training doctors and surgeons, right?

industries, shops, everything could change
Star Trek was not so far with their food synthesizer ;)
