Fiber, CO2 or UV Laser Marking: Which Source Fits the Application?

Short answer

Source names are not substitutes for application testing. Define the substrate, coating, mark content, contrast, depth, permanence, readability, heat sensitivity, geometry and cycle; then validate samples using the exact proposed configuration.

Define the mark

Specify text, logo, code, serial, data matrix or traceability requirement, including size, grade, verification method and expected environment.

Test material interaction

Different metals, plastics, coatings and finishes respond differently. Use representative material batches and record visual, dimensional and functional effects.

Plan integration

Review focus, field size, part presentation, fixtures, guarding, extraction, vision, code data, line speed, rejects and rework. Safety controls must match the exact system.

Decision inputs

• Material and coating

• Mark type and permanence

• Contrast, depth and readability

• Part geometry and field size

• Cycle and data integration

• Safety, extraction and validation

Frequently Asked Questions

Is fiber laser only for metal?

Do not generalize; suitability must be proven on the actual substrate and configuration.

Can a visual sample prove code quality?

No. Codes should be verified using the required inspection method.

Next step

Send representative samples and the required mark file for controlled trials.
