Common Tips When Laser Engraving Different Materials-Wood
1. Wood (raw wood)
Wood is by far the most commonly used laser-machined material and is easy to engrave and cut. Light-colored woods such as birch, cherry or maple are easily vaporized by laser and that is why they are suitable for laser engraving. Each kind of wood has its own characteristics, and some are denser, such as hardwoods, which require more higher laser power when engraving or cutting. We recommend that you study the carving properties of wood before carving when you are not familiar with them.
2. The plywood
Engraving on plywood is not much different from engraving on wood, except that the depth of carving should not be too deep. The edges of cut plywood would also blacken like wood, depending on which wood the plywood is made of.
3. Wood engraving
Generally speaking, the engraving on wood is usually Yin engraving, and the depth when engraving is generally required to be deep. Therefore, power Settings are generally higher, such as hard wood may make the graphics become darker. If should make the color lighter, you can speed up the engraving and try to engrave several times. Some wood in the engraving will produce some soot attached to the wood surface, if the wood has been painted can be carefully wiped off with a wet cloth. However, if not painted may not wipe clean, resulting in finished surface contamination.
4. Wood cutting
Laser engraving machine cutting wood depth is generally within 5mm, this is because the laser power is small, such as slow cutting will cause wood burning. Specific operation can try to use large size lenses, and repeat cutting.
After wood engraving, there will be a feeling of being burned. And there will be a kind of original artistic beauty from the whole wood. The depth of its color mainly depends on laser power and engraving speed. But some woods are usually soft and you can't change the color no matter what you do (like birch). For the coloring of finished products, acrylic pigments can be used.
