Overview
Laser etching and engraving are both laser cutting processes that produce permanent marks on objects. Both applications use a high heat laser to cut into a material, creating a cavity or imprint that reveals writing or an image. Laser engraving and etching are often used to personalize or customize a workpiece. The application works on most kinds of material including wood, metal, plastics, glass, leather and acrylic.
The difference between the two applications mostly involves the depth of the cut. For engraving, the cut typically runs around 0.005 inches or deeper. For laser etching, the depth is usually no more than 0.001 inches, making it a great option for thin materials or small projects such as jewelry. Durable, fast and cost efficient, laser engraving and etching are used in the dental industry to label prosthesis like dentures and aligners, the jewelry industry to personalize pieces and the medical industry to hygienically mark medical devices.
