The MakerLegoBot can print 3D Lego models, using standard Lego bricks. In this video, a simple Lego house is printed from an MLCad model on my computer. The robot uses 3 Mindstorm NXT robot brick's and 9 motors. You can find more information and build instructions at http://www.battlebricks.com/makerlegobot
