What materials can be laser engraved?

‌Materials that can be laser engraved include:

‌Non-metallic materials: such as plexiglass, wood, leather, cloth, plastic, printing rubber plate, two-color plate, glass, synthetic crystal, horn, cardboard, density board, marble, jade, etc.

‌Metallic materials: such as galvanized copper, metal plate, plastic-sprayed metal, etc. It should be noted that materials such as pure copper and pure aluminum cannot usually be directly engraved with a laser, but can be engraved through special treatment (such as painting on the surface).

‌Other materials: such as paper, resin, alumina, etc.

‌Application areas and process characteristics of laser engraving:

‌Line processing: Use a laser beam to produce a clear line effect on the surface of the material.

‌Filling processing: All the surface layers of the material in a specific area are vaporized to form a concave effect.

‌Hollow processing: All the materials in a specific area are vaporized to form a hollow effect.

‌Cutting process‌: Projecting a laser beam onto the surface of an object for cutting, which is often used to make exquisite crafts and paper gifts‌.

‌Principles and techniques of laser engraving‌:

Laser engraving is to irradiate the surface of a material with a high-energy laser beam, vaporizing or melting the surface of the material, thereby achieving the engraving effect. The laser engraving system is mainly composed of a high-energy laser, a laser transmission system, and an optical system, and the energy per unit area is adjusted by adjusting the focal length‌.
