Non-EV Reprap 3D printer

Adrian Bowyer has pioneered an open source self replicating 3D printer design.The machine is known as Self Replicating Rapid prototyping machine or RepRap for short. Currently the machine can print about 50% of the parts needed to make a repilica of itself. Amazing stuff, The ability to print any plastic object you need yourself is quite exciting. I wonder what percentage of parts for an ev project you could print. Actually its still early days, but as the project gains wider popularity and the collective genius of the internet sets its mind to it you can be certain this will bear fruit.
