    It's different.
    I've a few pieces of the same stuff, that is about 15 years old, I can cut it decently, but engraving is junk. It takes more power/slower than cast.
    I don't use it for anything but fixtures.....

    25 - 30psi through a 1.5mm nozzle with a 2mm standoff nozzle height away from the work Bert and it will cut nicely. The Koi pumps that come with the usual chinese machines are no good for this stuff, they only produce about 7psi maximum and more usually 3psi, they give good volume but hopeless pressure. And don't try gluing it with any solvents, it will craze and edge crack for fun
    You did what !

    Extrude has a lower melting point and should cut easier. But engraving does not frost.

    Thanks for the replies, I guess I'll just scrap this stuff, not going to buy a new compressor

    Try no air at all, you might be surprised. The only reason I ever use air is to keep flareups down and to help blow the smoke away from the lens. My air nozzle is at least and inch and a half from the cut, and too big to generate any force.... what comes out is akin to gently blowing with your mouth- just enough to prevent flames and move smoke, it in no way 'assists' the cutting...

    Problem is Clark, Extruded melts as you say, it doesn't ablate that's why the edges roll over
    You did what !

    UPDATE
    after once again trying and failing to cut this stuff, I sent a piece to Kev to see if he could cut it. He informed me that this is LEXAN, aka polycarbonate. So I guess this I can't cut with my CO2.
    So now my ?is can I do anything with this stuff of should I just take it to the dump???
    I have 13 pieces about 3 to 4 feet long and 6.5 wide.

    You can engrave it and then cut it with woodworking tools. It's a great material and I'm sure you can find uses for it.

    I have cut on this but only 1 mm thick. Nasty smoke and brown char. But if I left the protective plastic on it was fine. my recommendation is that you do not touch the the parts without gloves as it made my fingers numb. So probably a good idea not to breathe the fumes. How thick is the material you are using?

    Yes it engraves ok. I was reading that a fine tooth table saw blade will cut it. I'm wondering if a led light base will lite it up nice like regular cast acrylic

    Guys, lexan releases chlorine gas when lasered. I wouldn’t recommend messing around with that stuff.

    Cut it with a router or saw blade but not the laser.

    Hi Bert,
    It will cut fine with an Acrylic saw blade, it's not nearly as good as acrylic for transferring light through the edges though. Maybe you can use it for protective covers or something? It's very tough stuff, used to use it mostly for large lighted sign cabinet faces. I use scraps to make scrapers, cut it to 1"x6" and put a bevel on the belt sander and make a chisel for scraping old vinyl and things like that. I always did a comparison for customers and took a piece of Acrylic and piece of Lexan and hit it with a hammer, the Acrylic shatters, the Lexan bounces!

    Stack two of those 1/4" sheets together and they'll stop a .22 long rifle, 4 sheets will stop a 9mm... Delvies use to have (may still) a 2" thick chunk of Lexan with a 30.06 bullet stuck in it- makes great motorcycle windshields too... It has its uses, but it's hard stuff to work with.
