Take a look below to see what the difference between laser marking and engraving is.
Laser engraving is usually the most common option for someone who wants something personalized or customized. When engraving, the surface of the material is removed and you can feel the difference caused by the new depth when you run your finger over the surface. You can engrave almost all kinds of metal, plastics, wood, leather and glass and as the surface has been burned off, the engraving will never wipe off. You can see a sample of logo engravings on an aluminum surface in the picture below. It has quite a good industrial feel to it.
Laser marking (or annealing) is very classy but less common and not all places will provide the service. In simple words, the laser beam heats the material and causes slight material property changes (oxidation) under the surface. As a result, the material turns black but the surface is left intact and you won’t even feel a thing when running your finger over it. The best results are seen with metals.
