Laser engraving, which is a subset of laser marking, is the practice of using lasers to engrave an
object. Laser marking, on the other hand, is a broader category of methods to leave marks on an
object, which also includes color change due to chemical/molecular alteration, charring, foaming,
melting, ablation, and more. The technique does not involve the use of inks, nor does it involve tool
bits which contact the engraving surface and wear out, giving it an advantage over alternative
engraving or marking technologies where inks or bit heads have to be replaced regularly.

The impact of laser marking has been more pronounced for specially designed "laserable" materials
and also for some paints. These include laser-sensitive polymers and novel metal alloys.

The term laser marking is also used as a generic term covering a broad spectrum of surfacing
techniques including printing, hot-branding and laser bonding. The machines for laser engraving and
laser marking are the same, so that the two terms are sometimes confused by those without
knowledge or experience in the practice.

Materials that can be engraved: wood, plastic, metal, coated metals, stone, glass and jewellery.
