I am trying to cut a piece of fiberglass that is 1/8 thick, I have a universal laser cutter that has a 40 watt tube in it. I am getting a melting affect and a poor edge with 80 percent power and 2 in a minute with 150 PPI . Anny suggestions would be welcome.


Thanks

We useed to cut plastic by 40W CO2 glass laser and had same issue, then we switch to 60W and decrease the power setting a little bit and increase the cutting speed little bit, its working, edge looks neat. wish it helps

Hi,
Just doing a follow up to see what success you had in cutting the fiberglass.
Did it all turn out the way you hoped?
Rich.

I have cut Acrylic, ABS , Rubbers , and a few other plastics, But I have not figured out how to cut fiberglass with much success. I have tried to lower power and do multiple passes to limit the burnt edge, but it still isn't pretty like acrylic.

Let me know if you figure out a good way to cut it.

Do you have machines that can mill it?
Most PCB shops use a hog-out type end mill to cut PCB material (fiberglass) and the edges look very nice (sorry if the description is not very clear, let me know if sources are needed).
