3D Printers to make body parts

3D printers work by slowly layering a substance, usually a polymer, until the object is created. You can actually buy an open-source 3D printer from Makerbot for a bit over a thousand bucks.

Some people use 3D printers to create interesting food items.

Lately, we have been experimenting with live cells. Need a new heart? Simply print one up from cells cultured from your own body.

I can think of some body parts that people here might want printed and installed.

The good news? This technology is a whole lot closer to deployment than nanobots and the like.
