The usual mechanical machine type laser engraving cannot economically process points of varying thickness and therefore cannot achieve a contrasting presentation. The laser engraving machine, on the other hand, can realize laser engraving through the tending method, and thus has natural superiority at the level of the main expression of contrast. Therefore, when designing a laser engraving program, the contrast presentation form should be chosen as much as possible.handheld laser marking machine The advantage of doing so is not only to reduce the cost of the dyeing and processing process and save money; on the other hand, it also enriches the laser engraving presentation and enhances the pattern's sense of hierarchy. When customers use laser engraving machine, they can first fill the inside of the pattern with different contrast (text needs to be converted to pattern first), and then choose black and white mode for laser engraving output. Different dot effects can be tried, and the precision is usually no more than 500 dpi setting.

Raw materials for laser engraving

Wood (unprocessed wood)

Wood is by far the most commonly used raw material for laser processing and is very easy to laser engrave and cut.little pecker laser engraver Light colored woods such as birch, cherry or maple are easily vaporized by the laser, making them ideal for laser engraving. Each type of wood has its own unique characteristics and some are more compact, such as hardwoods, which require the use of higher laser output power when laser engraving or cutting. We recommend understanding the laser engraving characteristics of less familiar woods before laser engraving them.

Plywood

Laser engraving on plywood is virtually the same as laser engraving on wood, except that the depth of laser engraving should not be too deep. The edges of the laser cut plywood will also darken like the wood, the key is to see what kind of wood the plywood is made of.

Laser engraving on wood

In general, laser engraving on wood is usually in the form of carving out and the laser engraving depth is usually required to be deep. As a result, the output power is usually arranged higher, and if harder wood is encountered it may make the color of the pattern after laser engraving darker. If you want to make the color lighter, you can speed up the laser engraving speed and try to engrave several times. Some wood will produce some soot attached to the surface of the wood during laser engraving, if the wood has been painted, it can be carefully wiped away with a damp cloth; if it is not painted it may not be wiped clean, resulting in surface staining of the finished product.
