Cutting Styrene Plastic? Answered

I use .010" to .060" styrene plastic for making patterns for my casting business. What kind of power is needed for this type of material? Also, do laser cutters have regulated power controls for cutting small areas out of thin plastic?

Regards,

Styrene isn't an approved material for cutting in our shop. It releases chlorine gas (deadly) and tends to catch fire. That being said, you might find a service to cut it for you. This forum has some info on it you might find useful. Like they say in the forum, I would suspect that plastic this thin would have a tendency to warp, but you might be able to dial in the speed / power to minimize that.

In my opinion though, you'd be much better off using a CNC machine with a drag knife:

My next class is going to be CNC, so it might be worth your time to look into this option.

Styrene can't release chlorine gas, since it doesn't contain chlorine, just carbon & hydrogen (C8H8)n. You may be thinking of vinyl (PVC).

What Kiteman said. Styrene it perfectly fine. Romark is made of styrene and is a laserable product. PVC,i.e. Sintra,is probably what Jon was referring to.
