Advantages of UV Laser: UV light is absorbed more than longer wavelengths by most materials. Also, the laser photons directly break interatomic bonds in the plastic substrate causing a cold, photochemical interaction with any fillers or pigments, which in return eliminates any heat affected zone (HAZ) or changes to the surrounding material. For most plastics that appear white, this pigment is TiO2, which strongly absorbs the UV light and then undergoes a change in crystalline structure. This renders the substance dark, producing a smooth, highly legible mark within the bulk material, instead of at the surface. Because the mark is actually subsurface, it doesn’t provide a possible home for bacteria, and it is nearly impossible to alter or deface without destroying the material itself.
