Plywood – Laser Cutting and Engraving
The use of plywood in laser cutting is especially popular with the arts and crafts. Cutting is done without any wear, it’s dust-free, and it’s precise. Perfect finishes without any post-production operation facilitate and encourage its use. The slight oxidation (browning) of the cutting edges even gives the object a certain aesthetic.
Plywood can be worked like solid wood: it can be sawed, nailed, screwed, glued, etc.
The wood always works as a function of the relative humidity of the air, the temperature, exposure to light and air. Avoid major fluctuations in temperature and humidity. Like raw wood, plywood requires a minimum amount of protection. Protective waterproofing or water repellent products should do the trick. You can also apply a varnish. To clean a piece of plywood, use a clean, soft, lint-free cloth. If you have stubborn stains, you can use sandpaper, and you should sand in the direction of the wood grain.
Laser Precision for Laser Cutting and Laser Engraving
Laser cuts and engraves material by burning its surface. Therefore, the sides of the piece tend to be darkened, and are marked slightly on the edges. Sometimes, marks appear on the cutting line. The sides of the part cut in Plywood might stain skin or clothes, as a thin layer of black wood powder remains on the part.
When burning the surface, the laser also leaves a kerf of a width that can vary, depending on the type of material and the thickness chosen.
When designing your project, you need to take this kerf into account, and plan for a surplus of material accordingly.
