The 4 most important elements that affect laser engraving are:
Engraving speed, laser power, engraving accuracy, material.
A specific material needs to absorb a certain amount of laser energy to achieve a certain effect. The absorbed energy is laser energy = laser power / engraving speed. Therefore, to increase the laser energy absorbed by the material, one is to increase the laser power; two, to reduce the engraving speed, which method is used depends on the material and the final engraving effect. Average users avoid speeding up because that reduces productivity.
In addition to speed, the engraving accuracy also has a very big impact on the effect. The use of 500dpi from the practical experience with 600dpi precision carved items with the naked eye can't see much difference, general users will use 500dpi to complete most of the work only in the cutting or when you need a high energy density will use 600dpi or higher settings, so decided to impact on the final effect of the sculpture I'm afraid carving material. New users may not know much about the characteristics of materials, nor do they have a deep understanding of the engraving forms of different materials. Here are some of the commonly used carving materials and carving methods of presentation.

First, the gray performance
Laser engraving is a method of engraving, with a natural advantage in the performance of grayscale. Therefore in the design can be used as carving gray forms, it has two advantages, one is to reduce the coloring process, saving the cost; two is to enrich the carving performance means, increase the sense of hierarchy graph. Users in use, first in the graphics to do different gray filling, engraving output, select black and white mode, you can try different dot effect, the accuracy is generally not more than 500dpi.
Two. Engraving materials
1, wood
A, logs (unprocessed wood). Wood is the most commonly used laser material. It is easy to engrave and cut. Light colored wood, such as birch, cherry, or maple, can be well blown by lasers and therefore more suitable for carving. Each kind of wood has the characteristics of being, some tight some, such as hardwood, will use more power in the laser engraving or cutting.
B plywood. It doesn't make much difference with wood. Just pay attention to the depth of engraving. The cut back edge will also blacken like wood.
2 density board
A, ordinary density panel. This is what we commonly used in MDF pallets that make signs lining, and black uneven carved pattern color, usually colored.
B, laser special density panel. Some density boards are specially designed for laser engraving. The carved patterns are uniform in color and good in color without staining.
C, clean, after carving, you can use a damp cloth to clean the surface of the mdf.
3, acrylic
A, acrylic. Acrylic is second only to wood, the most commonly used engraving materials, it is easy to be cut and carved, there are a variety of shapes and sizes, relatively speaking, lower cost. There are two kinds of organic glass production process: Casting and rolling, laser engraving mainly by casting organic glass production, because of the frost effect it produces after the laser engraving is very white, a sharp contrast with the original transparent texture, and organic glass rolling produced after the laser engraving is transparent, no a sufficient contrast. It is recommended to buy a product of high purity, or else the possibility of melting when the material is bought or carved or cut.
B, engraving
Under normal circumstances, the use of organic glass back carving, that is, from the front carved, followed by watching, which makes the finished product more three-dimensional. In the back carving, please mirror the image first, and the engraving speed is fast, the power is low. Such as engraving power is too high, the bottom will appear uneven stripes, such as hope to carve deeper, try to carve more than a few times.
C, clean
Acrylic pigments may be used, and other pigments may damage the finish of acrylics.
