6mm Baltic Birch Plywood

2 passes at 35W for clean cut.

2 passes at 30W for clean cut.

2 passes at 30W for clean cut.

2 passes at 30W for clean cut.

Thicker plywood. Sometimes needs a 2nd pass if there are voids in the core.

Equivalent to ~20mm/s. Boss official chart (bosslaser.com/laser-settings/) lists Sande plywood 1/4" at 100W: 70% power / speed 20 (native). Baltic birch at similar thickness aligns. Cross-referenced with Noisebridge 100W settings wiki and settingsmag.com. Voids or knots in lesser-grade ply may need 2 passes. High air assist. Power cap at 75% to preserve tube life.

Equivalent to ~15mm/s. From LightBurn forum (forum.lightburnsoftware.com/t/ruida-64xxg-c02-laser-80w-for-cutting-9mm-deep-into-18mm-plywood/18673) and community LA Hobby Guy (lahobbyguy.com). Voids in cheap plywood require 2 passes; premium birch (Baltic BB grade) often cuts in 1 pass at same settings. High air assist (20+ PSI). Keep power ≤80% to protect tube.

6mm birch needs 3 passes at 33W. Glue layers absorb energy unevenly — check sheet flatness. Air assist critical.

Thicker plywood. Occasional voids in core may require a 2nd pass. Drop to 150 speed if not cutting cleanly through.

6mm birch plywood needs 3 passes even at 40W diode. Glue layers absorb energy unevenly — check flatness. Air assist critical.

Birch at 6mm is denser than basswood. 2 passes needed. Air assist critical — glue layers can catch.

Thicker plywood. Sometimes needs a 2nd pass if there are voids in the core.

6mm plywood takes 3 passes. Multiple passes produce slightly more char — clean up with fine sandpaper.

What are the best laser settings for 6mm Baltic Birch Plywood?

A top-rated community setting for 6mm Baltic Birch Plywood on the OMTech Polar+ 55W is speed 17 mm/s, power 75%. There are 31 community-tested settings for 6mm Baltic Birch Plywood across 21 machines on this page.

Can a diode laser engrave or cut 6mm Baltic Birch Plywood?

Yes - there are 8 community settings for 6mm Baltic Birch Plywood on diode lasers and 23 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 6mm Baltic Birch Plywood?

23% of the community settings for 6mm Baltic Birch Plywood use air assist. Air assist is optional for most operations but can improve edge quality on cuts.

What speed and power to cut 6mm Baltic Birch Plywood in one pass?

Settings vary by machine wattage. For a 20W diode laser, cutting 6mm Baltic Birch Plywood typically requires high power (90–100%) at moderate speed (1500–3000 mm/min) with air assist. CO₂ lasers can cut 6mm material faster - 20–60 mm/s at 50–70% power is common. Check the settings table below for your specific machine.
