3D Printers To Make Human Organs

The physical world can be duplicated using a 3D printer.  The devices have already been used to make components for the aviation industry, full firing handguns, and tons of stuff for the auto industry.

So is it a shock to find them ready to make entire human organs made with the stem cells from the person needing them avoiding any chance of rejection? 

They call them bioplotters.
Theoretical physicist David Kaplan, from Johns Hopkins University ent to Z-Corp to see if they could reproduce one of his wrenches from the lab.
After a few minutes, Kaplan pulls the wrench from the tray and tries it on a bolt - it works!
