The samples were processed using the 20 watt Pulsed Fiber Laser equipped with a 160mm lens. In order to get the marks darker than what was currently being produced the beam was defocused approximately 6mm above the part. A low frequency was used to obtain the highest amount of beam intensity and a slow mark speed was used. The parameters that produced the best results were marking at 6mm above focus, 95% Power, 30 kHz and 1 “ per second mark speed. The mark darkens more and more with each consecutive pass, using 10-12 passes produced the best results during testing.

Samples were processed using a 20 watt Q-switched fiber laser through a 160mm F-theta lens. *Due to the curved angle of the piece the characters on the end are less deep. Recommend 50 watt fiber laser with 100 mm lens. The smallest sample is the height and width requested by customer. The longest sample is comparable to the height and width of the sample that the customer sent to us.

The samples were cut using the F100 CO2 marking system equipped with a 300 mm lens. 3 passes were used to make the cut rather than 1 slower pass, this was done to potentially reduce the amount of char and burning produced from the laser. The sections that are cut have been labeled 1-2 and 3-4. The numbers have been placed near to the edge that was cut by the laser.

The samples were cut using the 200 Watt SMB 1200 FL cutting system. The PET film was cut using the pattern requested by the customer. While processing the samples an emphasis was placed on producing a cut with little to no residue left on the samples. The end result was a clean cut with crisp edges and minimal to zero residues. The only drawback while cutting the PET film was overcoming the air-bubbles contained in the protective layers. The drawbacks from the air bubbles were minimal and basically resulted in providing an opportunity for leaving residue on the sample, the air bubbles at times made it difficult to cut cleanly through the protective layer. This occurrence was minimal and the samples can still be easily removed once cut out. The final samples were cut out from a whole sheet using an array of 6×7 pieces.

The samples were cut using the 200 Watt SMB 1200 FL cutting system. Each foam sample was cut with a 1″ x 1.5″ box kiss cut and also cut through. The thicker foam sheets would benefit from a longer focal length lens then 3.75″ lens used for the application.
Laser Cutting Acrylic
Application Details
The Application was done with a low power system in the lab. The recommendation for this process would be for a minimum of 100watt laser for projected cutting speeds of 1mm per second. 100-watt laser projected 50mm plus per second.200-watt laser projected 100 mm plus per second cutting speeds.

Application Details
The sample was cut through all 3 layers completely and consistent at a speed of 250mm per second. however, with a smaller focus lens, it is possible to increase its speed up to 300mm/sec. Two protection films (clear and green) produce a great amount of smoke and residue while cutting, which contaminates the sample very strongly. No cleaning was performed on the sample after cutting.
