Conservative starting point derived from the 20W-class diode baseline — a 40W module should handle this with room to spare; faster cuts/fewer passes are likely achievable once you test on scrap.

What materials can the Bambu Lab Laser Module 40W engrave or cut?

The Bambu Lab Laser Module 40W has community-tested settings for Slate, Genuine Leather, 3mm MDF, 3mm Clear Acrylic, 3mm Basswood Plywood. Results vary by material batch, focus, and ambient conditions: always test on scrap first.

Is the Bambu Lab Laser Module 40W compatible with LightBurn?

The Bambu Lab Laser Module 40W uses Bambu Studio. LightBurn compatibility may be possible via a community-built device profile.

What settings should I use to cut Genuine Leather on the Bambu Lab Laser Module 40W?

A community-tested starting point is speed 600 mm/min, power 75% in a single pass. Enable air assist for a cleaner edge. Always run a test cut on scrap to confirm before committing to your project.

Can the Bambu Lab Laser Module 40W engrave metal?

Diode lasers can mark anodized aluminium, coated metals, and powder-coated surfaces without any spray. For bare steel, brass, or copper you need a marking compound like Cermark or Dry Moly. Fiber lasers mark bare metal directly without any coating.
