Laser cutting plywood.
Plywood is one of the most popular laser materials — strong, affordable, and clean-cutting. But not all plywood lasers well. Here is what to know.
Baltic birch is the standard
Not all plywood cuts the same. Baltic birch plywood is the standard for laser work because it is void-free — its thin birch plies are consistent all the way through, so the beam cuts evenly and the edge comes out clean. We cut it up to about 1/4″ thick.
Big-box construction and hardware-store plywood is a different story. Hidden voids, knots, patches, and inconsistent glue mean the laser can sail through in one spot and stall in the next, leaving an incomplete cut. We can run it, but results vary — for anything that matters, Baltic birch is worth it.
What the cut edge looks like
Plywood cuts with a light toasted, caramel-colored edge where the beam passes. Many people like that look and leave it; if you want it lighter, the edge sands back easily, or we can mask the surface before cutting to keep the faces clean.
Engraving works well on plywood too — the laser darkens the birch surface for logos, labels, and artwork, and we can cut and engrave in the same pass by mapping operations to colors in your file.
Press-fit joints and living hinges
Plywood is excellent for designs that assemble without glue or hardware — slot-together panels, finger joints, and tab-and-slot boxes. Cut correctly, the pieces press together and hold. The laser can also cut a living hinge: a pattern of fine relief cuts that lets rigid plywood flex into curves.
The key is accounting for two things: the kerf (the small width the beam removes) and the true thickness of your plywood, which is often slightly under the nominal size. We dial joints in so they fit snugly rather than loose or impossible.
Designing for plywood
Send vector files (AI, DXF, or PDF) at 1:1 scale. Tell us the exact plywood and thickness you are using so we can tune power and set joint tolerances. For press-fit work we recommend a quick test of one joint before committing to the full run, and for living hinges the grain direction affects how well the hinge flexes — send the design and we will advise.
Common questions
What plywood do you recommend for laser cutting?
Baltic birch plywood. It is void-free and consistent, so it cuts evenly with a clean edge. We cut it up to about 1/4″ thick.
Can you cut hardware-store plywood?
We can, but results vary — construction plywood has hidden voids, knots, and inconsistent glue that can leave incomplete cuts. For anything important, Baltic birch is worth the upgrade.
How thick of plywood can you cut?
Up to about 1/4″ on Baltic birch. Thicker or denser stock may be possible at slower speeds — send the details and we will confirm.
Do you cut MDF?
No. MDF cuts, but it produces heavy smoke, formaldehyde-based glue fumes, and a badly charred edge, so we do not run it. Baltic birch is the better choice in almost every case.
Will the cut edge be burnt?
Plywood cuts with a light toasted caramel edge. It sands back easily if you want it lighter, or we can mask the surface before cutting to keep the faces clean.
