Laser Settings for Plywood & Birch Ply
Can you laser cut and engrave plywood?
Yes — laser-grade Baltic birch plywood is the single most popular hobby laser material. It cuts cleanly on diode and CO2 lasers and engraves with excellent contrast. Cheap construction ply is less reliable: internal voids and glue pockets cause failed cuts.

PrepPreparation & technique
Mask the face with tape before engraving to avoid the brown burn halo. Cut with air assist on, over a honeycomb or pin bed.
⚠ SafetyPlywood smoke is heavy in fine particulates and the glue adds formaldehyde — run extraction on every job and never leave a cutting job unattended.
