Equivalent to ~25mm/s. Boss Laser official settings reference (bosslaser.com/laser-settings/) lists 100W acrylic at ~40% power/15 speed in native units; cross-referenced with Pumping Station One Boss Laser wiki (wiki.pumpingstationone.org/wiki/Boss_Laser_Settings) and settingsmag.com chart. Low air pressure (8–12 PSI) for clear flame-polished edges on cast acrylic. Boss native speed units are relative (0–100 scale) — LightBurn mm/s equivalent is ~25mm/s.

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.

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.

What are the best laser settings for 3mm Clear Acrylic (Cast)?

A top-rated community setting for 3mm Clear Acrylic (Cast) on the ComMarker B6 20W UV is speed 350 mm/min, power ?. There are 110 community-tested settings for 3mm Clear Acrylic (Cast) across 53 machines on this page.

Can a diode laser engrave or cut 3mm Clear Acrylic (Cast)?

Yes - there are 58 community settings for 3mm Clear Acrylic (Cast) on diode lasers and 48 on CO₂ lasers. CO₂ lasers generally cut faster and cleaner, but modern high-wattage diode lasers handle most acrylic work well.

Do I need air assist for 3mm Clear Acrylic (Cast)?

3% of the community settings for 3mm Clear Acrylic (Cast) use air assist. Air assist is optional for most operations but can improve edge quality on cuts.

What speed and power to cut 3mm Clear Acrylic (Cast) in one pass?

Settings vary by machine wattage. For a 20W diode laser, cutting 3mm Clear Acrylic (Cast) typically requires high power (90–100%) at moderate speed (1500–3000 mm/min) with air assist. CO₂ lasers can cut 3mm material faster - 20–60 mm/s at 50–70% power is common. Check the settings table below for your specific machine.
