How Laser Engraving Works
Laser engraving employs a focused laser beam to vaporize the material’s surface, creating permanent marks. The process begins with the laser machine directing a beam of light onto the material. The energy from the laser raises the temperature of the material, causing it to vaporize and leave behind a clean and precise engraving. Different types of lasers (CO2, fiber, UV, and diode) have distinctive properties that make them suitable for specific materials and applications.
For instance, CO2 lasers are widely used for organic materials, while fiber lasers are exceptional for metals. Understanding these differences is crucial for selecting the right type of laser engraving for your project.
