If you were impressed by the last post on 3D printing, then this gets better. This is a totally mechanical 3D printer. Meaning, it is not driven by a whole bunch of stepper motors, sensors and control systems. It has a weight driven chain transmission and ratchet-pawl mechanism. Obviously, the resolution of the printing process is not very fine. Any errors are quite easily detected by naked eyes.
