Laser engraving is a process that uses a focused beam of light to permanently mark an object. It works by directing the laser's energy onto the surface of the material, which causes it to evaporate or burn away. Laser engraving can be used on a variety of materials, including metals, plastics, wood, and glass. The result is a precise and permanent mark that won't fade over time. Laser engraving can be used for creating logos, text, images, patterns, and more. It is often used in industrial settings for product identification and labeling purposes, but can also be used for decorative purposes in jewelry making or other craft projects.
