Equivalent to ~400mm/s. High speed + low power for cast acrylic produces a bright frosted white engrave. DPI: 254–300 LPI. Source: LightBurn forum (forum.lightburnsoftware.com/t/acrylic-cutting-and-engraving/68186) and OMTech knowledge base (omtech.com/blogs/knowledge/material-settings-for-laser-engravers). Reduce power if engraving goes too deep.

💨 Air Assist

Equivalent to ~20mm/s. Community consensus from LightBurn forum (forum.lightburnsoftware.com/t/omtech-80w-laser-won-t-cut-through-acrylic/110337) and CNCZone reports 18–22mm/s at 60–70% for clean single-pass cuts on cast acrylic. Use LOW air pressure (8–12 PSI) to avoid frosting the edge. Extruded acrylic may need 1 extra pass.

"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."
