Fiber vs. CO2 vs. UV Laser Marking: Which Is Right for You?
Choosing between fiber, CO2 and UV laser marking depends on your material, the finish you need, production speed and the level of detail required. Each laser type is designed for different applications, so matching the technology to your process is essential.
Fiber laser marking
Fiber lasers are widely used for permanent marking on metals such as stainless steel, aluminium, brass and copper. They are suitable for serial numbers, QR codes, barcodes, logos and traceability information on industrial components.
Best suited to many metals and some engineered plastics.
Produces durable, high-contrast identification marks.
Suitable for industrial components and production environments.
Available in configurations for fast, repeatable marking.
CO2 laser marking
CO2 lasers are commonly selected for non-metal materials, including wood, acrylic, glass, leather, rubber, paper and selected plastics. They are useful for branding, decorative engraving, signage and product personalization.
Well suited to wood, acrylic, glass and many non-metal surfaces.
Supports detailed engraving and customized designs.
Useful for signage, packaging, gifts and decorative products.
Can also support cutting applications when configured appropriately.
UV laser marking
UV lasers are designed for high-precision marking with limited heat transfer. They are often considered for plastics, glass, electronics and other sensitive materials where fine detail and surface quality are important.
Suitable for delicate or heat-sensitive materials.
Supports fine text, codes and detailed graphics.
Useful in electronics, packaging and precision identification.
Requires testing on the exact material for the best settings.
Which laser marking technology should you choose?
Begin with your material and application. Fiber is typically the starting point for metal components, CO2 for many non-metal products, and UV for sensitive surfaces requiring precise, low-heat marking. Production volume, working area, automation and software requirements should also be evaluated.
Why sample testing matters
The same material can behave differently depending on its coating, colour, thickness and finish. A demonstration using your own product or sample helps confirm mark contrast, speed, readability and overall appearance before purchase.
