Fiber vs CO₂ vs UV Laser: Which Laser Technology Is Right for You?
Fiber, CO₂, and UV laser technologies are the three main laser marking solutions optimized for different materials and applications. While fiber lasers offer high performance on metal surfaces, CO₂ lasers stand out for organic materials, and UV lasers are preferred for precise and micro-scale applications. The right laser selection should be determined according to material type, production speed, marking quality, and automation requirements. This guide helps you make the right choice by comparing the three laser technologies based on technical criteria.
