Can I just throw a note of caution in here...
If you're cutting any sort of plastics with a source of heat (such as a laser), please ensure you have ventilation and lots of it. Plastics can give off some pretty toxic fumes and you need to get these away quickly, preferably with an extractor at the source of the cut.
You can thank me for saving your life later lol
