2 Name: RepRap Version 1.0 "Darwin"

Material: Biodegradable plastic or polyester

Price: $500 to $900, depending on assembly

What it does: Short for replicating rapid prototyper, the RepRap is the brainchild of Adrian Bowyer, a mechanical engineer at the University of Bath in England who figured that fabbers would become a lot cheaper and more accessible if they could build their own bodies... http://reprap.org
