Laser engraving, laser marking, and laser etching are processed but have subtle differences. Here is a look at what makes these three different from one another:
Laser engraving – A process where a high-powered laser is used to physically remove the surface layer of the material, creating a cavity that reveals an image.
Laser marking – This uses a lower-powered laser to create high-contrast markings on the surface of a material without disrupting the material itself. This means that the surface of the material is discolored but left intact, unlike laser engraving, which actually removes part of the surface of the engraved material to leave an image.
Laser etching – This is a process where a high-heat laser beam is used to melt the surface of the target material. The melted material expands and causes a slightly raised mark that reveals the desired image.
