> The RepRap Darwin has already successfully manufactured all of its custom parts except for the extruder nozzle and circuit boards, leaving only a few hundred dollars' worth of common off-the-shelf "vitamin" parts So it can extrude plastic, but can't extrude * nozzles * circuit boards * guide rails * screws * motors * steel rods * thermocouple sensor * rotary encoder * etc., etc., etc. That's quite a lot of "vitamins" (to use the propoganda term). Take a look at the Darwin. http://www.reprap.org/pub/Main/WebHome/darwin-small.jpg http://www.reprap.org/pub/Main/WebHome/darwin-small.jpg I believe that of everything you see there, the only things that the RepRap creates itself are the small white plastic bits...maybe 10% of the machine by volume, 5% by weight, and 1% by complexity. > Check out the RepRap blog I have.
