Anyone ever cut Delrin (Acetal) sheets? I have an inquiry to do some special gaskets .01” thick but my laser is in the middle of me installing a Peltier cooling system so I can’t even do a test cut.
It’s possible. Before I got my own laser I had ordered a couple leather stamps that were laser engraved onto delrin pieces. The guy that did it was using an older co2 laser.
I’ve cut 1/16" delrin for a few projects. Cuts pretty nice. Just leaves a little residue on the bed.
What power level and cutting speed did you use to cut 1/16" thick delrin?
Hi @brainy1985! This is content that was imported to MakerForums from Google+ when Google shut down Google+ (thus the gplus label), and @Bill_Keeter has not yet logged into Maker Forums, so he won’t get notification of your question, sadly. 
However, there might be others here with relevant experience. 
I’d cut some Delrin to make some gears a few years ago on my K40 CO2 laser. IIRC it was 2-3mm thick and was tricky getting the air assist and power tuned well enough to keep the melting down. Too much heat and it’ll melt back quite a bit away from the cut.

I lasercut 3/32" and 1/16" thick delrin from time to time. I make guitar picks for myself. Cuts well.
