The part was marked using a 20 Watt Pulsed Fiber Laser using a 254 mm lens. Four passes were used to ablate the sample, 2 passes each in opposite direction. For the first 2 passes, the sample was ablated using 5 Watts of power, frequency of 80 kHz, speed of 5″ per second, resulting in a cycle time of 6 minutes and 54 seconds. The remaining 2 passes was ablated using 4 Watts of power, frequency of 80 kHz, speed of 20″ per second, resulting in a cycle time of 2 minutes and 20 seconds. The total cycle time to mark the sample is 9 minutes and 16 seconds. The cycle time can be decreased by almost half the time if we are able to have more samples and time to be able to set up more efficiently. We did not want to damage the white base and ablate the black paint if we would have more set up time in order to do it with better quality and half the cycle time.
