Laser Engraver Applications and Key Functions

Laser Engraver Applications and Key Functions

Using a laser engraver is as simple as operating a computer and a printer for paper printing. Various graphic design software can be used for creating designs, and a range of files, including scanned graphics, vectorized graphics, and various CAD files, can be effortlessly "printed" onto the engraving machine. The key distinction is that instead of applying toner to paper, a laser engraver projects laser beams onto a wide array of materials such as wood products, acrylic, plastic, metal plates, stone, and more, inducing physical and chemical reactions that result in intricate patterns.

1. Functions of a Laser Engraver

Dot Matrix Engraving

Dot matrix engraving resembles high-definition dot matrix printing. The laser head moves horizontally to engrave a line composed of a series of dots, then moves vertically to engrave multiple lines simultaneously, eventually forming a full-page image or text. Dot matrix engraving can be used for scanned graphics, text, and vectorized graphics.

Vector Cutting

In contrast to dot matrix engraving, vector cutting is performed along the outer contour of a graphic. This mode is commonly used for precision cutting through materials like wood, acrylic, paper, and can also be used for surface marking on various materials.

Engraving Speed

Engraving speed refers to the movement speed of the laser head, typically measured in IPS (inches per second). Higher speed translates to greater production efficiency. Speed also influences the depth of cutting. At a specific laser intensity, slower speed results in deeper cutting or engraving. Speed adjustments can be made using the engraver's control panel or the computer's print driver within a range of 1% to 100%, adjustable in 1% increments.

Engraving Intensity

Engraving intensity signifies the strength of the laser light hitting the material's surface. At a consistent engraving speed, higher intensity leads to greater cutting or engraving depth. Intensity can be adjusted using the laser engraver's control panel, with increased intensity resulting in both higher speed and deeper cutting depth.

Spot Size

The laser beam spot size can be modified using lenses with varying focal lengths. Smaller spot lenses are employed for high-resolution engraving, while larger spot lenses are suitable for lower resolution work. A smaller spot size yields finer engraved patterns. However, for vector cutting, a small spot laser with high precision is the preferred choice.

2. Application Fields of Laser Engravers
