The parts were laser 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.

The parts were marked using a 10 & 20 Watt Fiber Laser Marking System using a 160 mm lens. The parts were marked with both an etched mark and a dark surface mark. The etched marked was done using the 10 Watt Fiber laser and had a cycle time of 0.45 seconds. The dark surface marks were done with a 20 Watt Fiber Laser, the cycle time was 0.45 seconds. The two different types of marks were done to show variety and to provide more than one marking option. The parts were also marked while covered in the lubricant that was in the bag that the parts came in. The parts were not wiped off before being marked.

The parts were marked using a 20 Watt Pulsed Fiber Laser using a 160 mm lens. The samples were annealed to create brightly contrasting marks. The Brass sample was engraved and lightly etched, each with its own cycle time.
Engraved-1.63 secs, Light etch 2.18 secs.

The plastic cover was marked with a 20-watt q-switched ytterbium fiber laser with a 160 mm focal length lens. The part was laser marked with both a barcode along with the text. The marking was made to show the feasibility of the laser to imply what a typical cycle time and what type of contrast can be produced. The barcode was read well in the lab with Symbol DS 3407 Barcode Reader. The total time for the text and the barcode was 10.57 seconds.

UID marking was created using a 20-watt q-switched ytterbium fiber laser with a 160 mm focal length lens. The 160mm focal length lens has a working distance of 176mm from lens to part. The marks were created on the parts using a 2 step process. First, the light patch was etched onto the surface using 12 watts of power with a frequency of 30 kHz and speed of 50 inches per second, resulting in a cycle time of 0.99 seconds. Next, the 2D code and text were annealed onto the surface using 18 watts of power, with a frequency of 35kHz and a speed of 4 inches per second, resulting in cycle times of 7.08 seconds for the 2D Code and 1.5 seconds for the text. The total cycle time for all marks on the part was 9.5 seconds.

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.
