The parts were marked using a 20Watt Fiber Laser Marking System with a 160mm lens. The 160mm focal length lens has a working distance of 176mm from lens to part. Two different logos were marked on the samples on each end. The main logo had a cycle time of 1.67 seconds. The other logo had a cycle time of 2.59 seconds. The logos mark on the coated dark sample provided better contrast than the light material.
