Laser engraving works by using a high-powered laser to physically remove the surface layer of the material, creating a cavity that reveals an image. It’s typically used for logos, barcodes, QR codes and other text markings on plastics and metals.
Laser marking works by using a low-powered laser to mark the surface of a material without destroying the material itself. This is different from laser engraving. The surface of the material is only discolored but remains complete. And laser engraving is used on metal, thermoplastic, glass, leather and wooden surfaces.
Generally speaking, both can produce images in a variety of materials, but laser engraving is that it creates a cavity, vaporizing the surface of the material with a high-heat laser. And laser marking creates images creating markings without damage the surface layer of material.
