Laser Engraver Applications and Main Functions

Sep 29, 2021

Using a laser engraver is very simple, just like using a computer and a printer to print on paper. You can use a variety of graphics processing software to design, and scanned graphics, vectorized graphics and a variety of CAD files can be easily "printed" to the engraving machine. The only difference is that the printing is to apply toner to the paper, while the laser engraver projects the laser onto almost all materials such as wood products, acrylic, plastic plates, metal plates, stone, etc., through the laser and the material. The physical and chemical reactions between the sculptures produce patterns.


1. The function of laser engraver


Dot matrix engraving


Dot matrix engraving resembles high-definition dot matrix printing. The laser head swings left and right to engrave a line consisting of a series of dots each time, and then the laser head moves up and down to engrave multiple lines at the same time, and finally constitutes a full-page image or text. The scanned graphics, text and vectorized graphics can all be engraved by dot matrix.


Vector cut


Unlike dot matrix engraving, vector cutting is performed on the outer contour of the graphic. We usually use this mode of laser engraver to perform penetrating cutting on wood, acrylic, paper and other materials, and it can also perform marking operations on the surface of a variety of materials.


Engraving speed


Engraving speed refers to the moving speed of the laser head, usually expressed in IPS (inches per second). High speed brings high production efficiency. Speed is also used to control the depth of cutting. For a specific laser intensity, the slower the speed, the greater the depth of cutting or engraving. You can use the panel of the engraver or the computer's print driver to adjust the speed. In the range of 1% to 100%, the adjustment range is 1%.


Engraving intensity


Engraving intensity refers to the intensity of laser light hitting the surface of the material. For a specific engraving speed, the greater the intensity, the greater the depth of cutting or engraving. You can use the laser engraver panel to adjust the intensity. The greater the intensity, the greater the speed and the deeper the cutting depth.


Spot size


The size of the laser beam spot can be adjusted with lenses with different focal lengths. A lens with a small spot is used for high-resolution engraving. A lens with a large spot is used for lower resolution engraving. The smaller the spot, the finer the engraved pattern. But for vector cutting, a small spot laser with high precision is the best choice.
