How does laser engraving work?

Laser engraving machines consist of three main components: a laser source, a controller, and a focusing lens. The laser source emits a highly concentrated beam of light, which is directed towards the material to be engraved.

When the laser beam makes contact with the glass surface, it heats and vaporizes the material, creating a cavity or groove. The controller determines the direction, intensity, and speed of the laser beam, allowing for precise customization of the engraving.

Types of laser engraving machines

There are several types of laser engraving machines available in the market, each with its own strengths and limitations. The most common types include CO2 lasers, fiber lasers, and neodymium-doped yttrium aluminum garnet (Nd:YAG) lasers.

CO2 lasers are the most widely used for glass engraving due to their ability to work with a wide range of materials. Fiber lasers, on the other hand, are ideal for highly reflective materials such as metals. Nd:YAG lasers are renowned for their high precision and are often used in industrial settings.

When choosing a laser engraving machine, it is important to consider factors such as the size and thickness of the glass you are working with, the complexity of your projects, and your budget.
