Laser ablation occurs when a laser beam removes material from a localized area. Used in various industrial applications, this process can create permanent marks (laser marking), remove contaminants and coatings from surfaces (laser cleaning), modify a part’s roughness (laser texturing), cut through a surface (laser cutting) and much more.
If you are relatively new to laser technology, you are probably wondering what’s the difference between laser engraving and laser etching. And more importantly, which one is right for you?
Laser engraving is a process that vaporizes materials into fumes. The laser beam acts as a chisel, incising marks by removing layers from the surface of the material. The laser must hit localized areas with massive levels of energy to generate the high heat required for vaporization. In this article, you’ll find in-depth information on how laser engraving works
Laser etching is one of the most popular marking processes. But most people don’t really know what it means to etch a surface, and how it actually works. Let’s go step by step to understand how the surface melts, and how bumps and colored markings are created.
Metals have a tendency to get dirty, to corrode and to have unexciting surface finishes. To solve these issues coatings may be applied to metals. Aluminum gets anodized, steel gets painted and...
