The parts were marked using a 20 Watt Q-Switched Fiber Laser with a 160 mm lens. The handles were marked inside of the requested area designated with a pink box. The parts were tested for contrast, but some of the plastics did not produce a contrasting mark. The parameters used seemed to have the best results on all the different materials, 20 kHz, 20″ per second, and 12 watts. There were two different sized marks, one big and one small. The bigger mark had a cycle time of 1.56 seconds and the smaller, 1.14 seconds.
