Laser engraving on cast acrylic is best done using low power and high speed. If using a 50-watt laser system, best results can be achieved using a 20% power and 100% speed. 

Laser cutting cast acrylic is all about controlling the heat using the pulse rate or frequency. Excellent results can be achieved using a maximum pulse rate/frequency, 6% power and 100% speed setting.
