"Ekaggrat has come up with an interesting way to use existing 3D printers to make light paintings in 3 dimensions.

Your standard 3D printer is already capable of moving in 3d space, an already accepts Gcode to tell it where to move. Ekaggrat noted that there are a couple extra spots on his built in arduino in the printer he is using that can be used for things like turning an LED on and off.  So, he installed an LED at the extruder and set out to create a bit of custom code to tell the printer when and where to shine its LED."
