I saw a show that was looking into future tech, and they talked about printing 3D living body parts (in this case a heart). They take your stim cells, tell them to be heart cells, put them into the "ink cartridge" and printed it. This has already been tested to a degree. They printed a patern on a petri dish using live bacteria to see if they would servive the process and grow, and they did.
