How is Laser Engraving Different from Laser Marking?

Comparing Laser Engraving and Laser Marking Technologies

The processes of Lasor engraving and marking don’t have the same application as laser systems. In laser engraving, most of the material located at the surface is removed, and the design is made deepest and most permanent, which is why there is a fair amount of alteration of the substrate. On the other hand, laser marking is efficient enough to improve the properties of the surface, such as texture or color, but, in most instances, does not contact this much material. In most cases, this procedure is more superficial and makes a type of marking that can be seen clearly and is left shallow; therefore, it is not deepened. In conclusion, the selection between both procedures is made on the basis of the requirements of the application, which include required intensity, depth, and aesthetic requirements, among others.

Applications of Laser Engraving Machines
