Make sure to buy a couple extra for test cutting.. I know that you can do acryllic on the laser cutter, but not sure about polypropylene.
I have some scrap polypropylene for testing. I’ve also found this, which gives some hints for the settings, they’re quite thin so a couple of low-power passes will probably be best.
