"One VERY important thing to know when lasercutting styrene in particular is that it produces VERY toxic gases when cut, so make sure your laser cutter or the facility you hand it off to has proper ventilation. If you don't have a safe way to vent it out of your closed space, don't cut styrene. Also, the best thing to use when joining styrene is the MEK family of solvents, which can be neurotoxic without ventilation, so be careful. "
