Material: Composite Method Used: Cutting Depth: Through Laser Type: CO2 Focal Length Lens: 300mm Power: 25% ~ 25 Watts Frequency: 5 kHz Speed: 25″ per sec Passes: 3 Cycle Time: 0.422 seconds 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.

Material: Acrylic Method Used: etch Depth: <.002 Laser Type: 20 Watt CW Fiber Laser Focal Length Lens: 254mm Power: 40% Speed: 10 inches per second Passes: 2 Cycle Time: 50.5 seconds Samples were processed using a 20 watt CW fiber laser through a 254mm F-theta lens. To increase the contrast in the brail bars you may need to increase the amount of paint use in the colored area. (race track color).

Material: PET Method Used: Cutting Depth: Through Laser Type: CO2 200W Focal Length Lens: 3.75″ lens Power: ~50 Watts Frequency: 4 kHz Speed: 200mm per sec Passes: 1 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.

Material: Foam Method Used: Cutting Depth: Kiss & (Through) Laser Type: CO2 Focal Length Lens: 3.75″ Power: 40 Watts (60 Watts) Frequency: 3 kHz (3 kHz) Modulated Speed: 300mm (300mm) Passes: 1 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.

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.

Material: Titanium Method Used: Annealing Depth: Surface Laser Type: Pulsed Fiber Focal Length Lens: 160mm Power: 95% Frequency: 30 kHz Speed: 1″ per sec Passes: 12 Cycle Time: 26.52 seconds 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.

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.
