UV lasers are finding many innovative applications thanks to their ability to cure resins, clear coatings, and mark a wide array of materials. With wavelengths in the ultraviolet spectrum, these lasers can trigger chemical reactions for curing, etching, and engraving uses.
A major application is 3D printing. UV lasers are commonly used in stereo lithography printing where lasers cure liquid photopolymer resins, layer by layer, into solid 3D objects. This allows intricate and detailed prints of prototypes, models, and end-use parts with moving components.
In manufacturing, UV lasers can mark high precision codes, logos and information onto product packaging faster than traditional inkjet or thermal transfer methods. They also etch serial numbers, dates and other identifiers discretely and permanently onto metal or plastic parts during production.
In dentistry, UV lasers play an important role in cavity curing. By precisely curing composite resins in fillings, they produce strong, long-lasting repairs. They can also alter the surface of dental implants to encourage bone cell adhesion for better integration.
Beyond industrial uses, UV lasers have applications in art and design. They allow permanent engraving of fine textures and patterns into materials like glass, stone and ceramics. This enables one-of-a-kind works of art as well as etched branding and logos on high-end products.
As UV laser technology advances, the power and precision of these lasers will continue to open new application possibilities by driving highly exact photo-initiated reactions. Their touchless, contact-free processing capabilities make them a valuable long-term manufacturing and production tool.
