This page lists 18 community-tested settings for 3mm Clear Acrylic. Acrylic cuts and engraves cleanly on both CO2 and diode lasers. Cast acrylic gives a frosted edge on cuts; extruded acrylic melts and polishes.
Clear acrylic cuts beautifully with CO2 — polished flame edge. Typical K40 setting: 5–7mm/s at 90% for 3mm clear in one pass. Remove masking immediately after cutting. Colored acrylic varies slightly — black needs a touch less, yellow/orange a touch more. Ventilate well.
"Used it with a Glowforge — engraved beautifully with no changes. I will be purchasing more digital downloads from this shop."

"This template made my slate coasters so much easier. 4×4 coasters from Michaels drop in easily and are easy to remove. Def worth it."
