I’ve loved the idea of 3d printing for a long time. I’ve followed the RepRap for a while. Open Source Hardware strikes me as a compelling idea – anybody who has read Feynman’s memoirs knows that playing with building thinds is important for any young scientist.
Well, here’s a new awesome application to the idea of printed 3d materials: printing organs. The idea is that a computer prints a scaffold impregnated with human cells which then grow into the desired organ which is then implanted. The current state-of-the-art is printed veins, but other things are coming soon!
