Thingiverse user villamany brings us his 3DP Laser Cutter/Engraver, the 3dpBurner, which he created using parts from his old RepRap 3D printer, along with inexpensive electronics being controlled by Arduino software. He used a common 1.6W blue laser diode, which is the integral part that does the engraving. The design for the laser cutter and engraver is fully functioning, customizable, and available for download at Thingiverse.
