Design Notes

Birch plywood has a smooth finish and is consistent in thickness. It laser cuts with a dark edge and engraving does not go through the veneer.

GRADING
Both sides of this plywood can have small oval shaped patches which are color-matched to the surrounding material. Tight pin knots, as well as some light mineral streaks, may be present. Inner cores are solid single piece veneers.

FLATNESS
Sometimes sheets of this material may not be very flat when we get it from the manufacturer. Unfortunately, this is the nature of material. The inherent tension in the grain of the wood and the way it is constructed means the panels can warp after manufacturing.

Be aware of this when designing for this material. If possible arrange your designs on P1 sized templates and layout designs in grid format on larger templates.

Grain direction will always run horizontally as drawn on the computer screen.

The manufacturers tolerance for the thickness of the materials is as follows:

Engraving Birch

There are 3 types of engraving possible with laser cutting. Area engraving, line engraving and a combination of both.

Area engraving is great it you need to mark a large area on the surface of the material. To specify area engraving set your shapes to have a fill color of black with RGB values of 0, 0, 0. The way this engraving is performed is like an old dot matrix printer except instead of dots of ink it uses pulses of the laser beam. This is a surface finish not deep enough to be used for pocketing or inlays. The depth of the engraving ranges between 0.1-0.3mm.

Line engraving is like a really shallow cut. To achieve this effect the stroke color to red with RGB values of 255, 0, 0 and set the stroke style to a width of 0.01 mm. The laser beam follows along the red lines that you have in your design and marks the surface of the material. The result is crisp but it can be a time consuming technique if you have a lot of small details like text.

Using a combination of both engraving types typically gets the best result. Set your shapes to have a fill color of black with RGB values of 0, 0, 0, the stroke color to red with RGB values of 255, 0, 0, and set the stroke style to a width of 0.01 mm. The line engraving causes the laser beam to trace around the edges of the engraved areas making them more crisp and bringing the details to life.

Typical Uses

Birch is commonly used for making scale models, jewelry, model boats, model airplanes, product housings, drones, clocks, prototyping, signage, etc.

Adhesives, joints and fastenings

Construction adhesives will bond birch well. Follow the adhesive manufacturer's instructions for application processes. Screw joints should be pre-drilled to avoid splitting.
