Lego Mill NXT_01
This 3D printer was built with Lego Mindstorms NXT and RCX, Lego Technic and a few parts designed by myself with approx. 2060 pieces.
You see the Lego brick printer, the printer head, the NXT stepper motors and sensors, a video camera at the A NXT brick is responsible for the 3 NXT stepper motors, the various sensors, the latalogging and finally the IR remote control of the RCX brick, which in turn controls the 2 motors feeding the printing material (hot glue!) into the heat head.
