One is that the laser produces its engraved mark with a non-contact method. Therefore the wear and tear associated with conventional tooling is not present. This also reduces potential product damage and deformation. The mark is permanent, concise and clean. Lasers also can engrave faster than many conventional methods, although sometimes one must experiment to find the most efficient settings.
Lasers also have the advantage of engraving onto materials that are unengraveable by other methods.
This includes wood and other materials. In addition, the same machine that can engrave also can be used to cut through thin materials. While lasers do emit a small amount of radiation, the low power and the kind of laser used for engraving produce minimal risk. Universal Laser Systems is required by law to adhere to certain safety features when building their equipment. Additionally, laser owners and operators are required to comply with certain regulations.
