Technical methods for engraving wood materials with laser engraving machines

Ordinary mechanical engraving cannot economically engrave dots of varying thickness and therefore does not have a gray scale representation. The laser engraving machine realizes engraving by means of dots, which has a natural advantage in terms of grayscale representation.handheld laser marking machine For this reason, in the design of the carving as far as possible to use grayscale form of expression, the benefits of this is on the one hand, reduce the coloring process, saving costs; on the other hand, rich in the means of expression of the carving, increasing the level of graphics. Users in the use of the first graphics to do different grayscale filling (text to be transformed into graphics first), engraving output selection of black and white mode, you can try the effect of different dots, the accuracy is generally not more than 500dpi.

Carving materials

Logs (unprocessed wood)

Wood is by far the most commonly used material for laser processing and is easy to engrave and cut. Light colored woods such as birch, cherry or maple are easily vaporized by the laser and are therefore more suitable for engraving. Each type of wood has its own characteristics, some are denser, such as hardwoods, and require more laser power when engraving or cutting. We recommend that you study the engraving characteristics of a wood you are not familiar with before engraving it.

Plywood

Engraving on plywood is not much different from engraving on wood, except that the depth of engraving should not be too deep.little pecker laser engraver The edges of cut plywood will also darken like wood, depending on the type of wood used to make the plywood.

Wood engraving

Generally speaking, the carving on the wood is usually negative carving, and the carving depth is generally required to be deeper. The power setting is generally higher, and if you encounter harder wood, the engraved figure may become darker in color. If you want to make the color lighter, increase the engraving speed and try to engrave more times. Certain woods will produce some soot on the surface of the wood when carving, if the wood has been painted with a wet cloth can be carefully wiped away, if it is not painted may not be wiped clean, resulting in the finished product surface contamination.

Wood Cutting

Laser engraving machine cutting wood depth is generally not deep, the maximum cutting depth depends on the wood material and laser power, such as cutting very thick wood, you can slow down the cutting speed, but may cause the wood to burn. For specific operation, you can try to use a large size lens and use the method of repeated cutting.

Coloring

Wood engraving will generally have a feeling of being burned, with the wood base color with a primitive artistic beauty, the depth of its color mainly depends on the laser power and engraving speed. However, some woods are usually softer in texture that you can't change their color no matter what (e.g. birch). For the coloring of the finished product, you can use acrylic pigments.
