While the practices of laser engraving and laser marking are similar, they differ slightly and have unique goals. Laser engraving uses a laser beam to physically remove the surface of a material and create a permanent mark that can withstand exposure to harsh environmental and usage conditions. This process is slower than laser marking, but produces more robust results.

Laser marking is the process of sending laser light through a lens and focusing it on the surface of a part. When the jet interacts with the surface of the material, the appearance or properties change slightly. Unlike laser engraving, marking permanently changes products without removing material.
