Equivalent to ~30mm/s. Boss official settings table (bosslaser.com/laser-settings/) for 100W MDF 1/4" lists power 80 at speed 5 (native units). 3mm is thinner so speed can increase and power decrease proportionally. Cross-referenced with CAMFive 100W reference chart and Noisebridge 100W wiki (noisebridge.net/wiki/Old_100W_Laser_Cutter_Settings_for_Known_Good_Materials). High air assist required.

Equivalent to ~25mm/s. Cross-referenced from LightBurn forum 80W MDF discussions and CAMFive 80W/100W power settings chart (camfivelaser.com). High air assist (20+ PSI) critical to clear MDF smoke and prevent flare-ups. MDF glue content varies — run a test cut first. Increase to 2 passes if using dense or moisture-affected MDF.

The Gadgeteer's xTool S1 review confirmed 13mm/s at 100% power cuts 3mm MDF cleanly in 1 pass with significantly less soot/char than lower-power machines. Air assist is included with the S1 and should always be used for MDF cuts — reduces char and smoke contamination of the lens. Some users report 15mm/s possible with very clean MDF. Use honeycomb table.

Community-established baseline for M1 10W on 3mm MDF: 100% power, 4mm/s, typically 2–3 passes depending on MDF density and glue content. Air assist strongly recommended — reduces char, clears smoke from kerf, and improves cut-through. The Gadgeteer M1 review noted 4mm/s as the typical cut speed vs 13mm/s on the 40W S1. Without air assist expect 3 passes minimum; with air assist 2 passes often sufficient. Always use honeycomb table to allow air through the cut.

Creality Community Forum (forum.creality.com/t/please-advise-with-best-settings-to-cut-mdf/2389): multiple users with Falcon (10W–22W) report 3mm MDF cutting at 100% power; recommended speeds range from 300–500 mm/min with 1–2 passes for 22W. LA Hobby Guy (t=5964) and LightBurn forum discuss MDF cutting for Falcon2 22W; Maker Forums (forum.makerforums.info/t/your-opinion-at-speed-power-for-cutting-mdf/83250) community consensus for ~20W diode is 400 mm/min / 100% / 2 passes. MDF produces significant smoke; air assist essential.

Creality Community Forum post (forum.creality.com/t/please-advise-with-best-settings-to-cut-mdf/2389): community discussion for a 5W Falcon cutting 2.5–3mm MDF; consensus is 100% power at 200–300 mm/min needing 3–5 passes. Maker Forums (forum.makerforums.info/t/your-opinion-at-speed-power-for-cutting-mdf/83250) suggests 30% power at 20 mm/s (1200 mm/min) for 10W, scaling that down implies very slow speed at full power for 5W. 3mm MDF is near the limit of the 5W; air assist is essential.

Identical laser module to X20 Pro. LA Hobby Guy forum (lahobbyguy.com/bb/viewtopic.php?t=4458 'cut and print settings Atomstack A20 pro') confirms A20 Pro users see similar MDF cutting behavior. One user reported 100mm/min at 100% power for 1 pass; 200mm/min / 2 passes with air assist is the more community-standard approach for cleaner results.

Community-sourced: Atomstack A20/X20 Pro forum users report 3mm MDF requires maximum power (100%) and slow speeds. One user confirmed 100mm/min at 100% power in 1 pass; 200mm/min in 2 passes (with air assist) is a more common balanced approach to reduce charring while ensuring full cut. MDF-core plywood confirmed harder to cut than veneer-core in same thickness.

Can a diode laser engrave or cut 3mm MDF?

Yes - there are 62 community settings for 3mm MDF on diode lasers and 49 on CO₂ lasers. CO₂ lasers generally cut faster and cleaner, but modern high-wattage diode lasers handle most wood work well.

Do I need air assist for 3mm MDF?

49% of the community settings for 3mm MDF use air assist. Air assist is optional for most operations but can improve edge quality on cuts.

What speed and power to cut 3mm MDF in one pass?

Settings vary by machine wattage. For a 20W diode laser, cutting 3mm MDF 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.
