In comparison to CO2 and Fiber laser technology, UV laser technology is significantly different.
UV engrave using a cold laser. This technology often known as the blue laser beam, has the ability to engrave with a very low rate heat. One of the key factors in this technology’s ability to engrave over a variety of materials is its light wave or UV light spectrum, which doesn’t heat the material surface like CO2 and fiber do. It enables the UV laser to mark on all plastics and other materials that react negatively to heat in a clear, highly precise manner.
All these materials can be engraved by UV laser:
ABS (Acrylonitrile butadiene styrene)
Polyvinyl Chloride (PVC)
Polylactic Acid (PLA)
Acetal (Polyoxymethylene, POM)
