‘60W MOPA Fiber vs. 6W UV, which one is better?’
There is a common misconception among beginners: Does higher laser power always mean better engraving results?
In reality, fiber lasers and UV lasers represent a distinction between "specialized" and "all-rounder" machines. Because of their different working principles, engraving performance cannot be simply measured by power alone.
Even when comparing a 60W MOPA fiber laser and a 6W UV laser, it is more accurate to evaluate them using two separate sets of standards.
Here's a quick breakdown:
MOPA: "Born for Metal". Fast, powerful, and perfect for metal. It's great for deep engraving, black/color marking, and pretty much everything metal-related.
UV: "Do-Everything" specialist. Super precise, works on a wide range of materials（1600+ varieties）, and shineswhen it comes to fine details and surface-level engraving.
1. WHY? What’s the Difference?
UV laser engravers use a much shorter wavelength (~355nm), use photochemical reaction that removes material. Deliver highly concentrated energy for cold marking which provides detailed laser etching while prevent burning or damaging the material.
Fiber laser engravers: operate at a longer wavelength (~1064nm), melt or vaporizing materials with heat.Making them ideal for heat-based processes such as deep metal engraving or metal cutting.
2.What Materials Can You Engrave?
UV laser engravers support over 1,600 material types and are ideal for engraving heat-sensitive and transparent materials such as crystal, glass, and ceramics. Using cold laser technology, they achieve high-precision laser marking without thermal damage. UV laser engravers perform fine metal marking, wood engraving, and fabric cutting and marking.
Fiber laser engravers excel at metalworking, hard plastic marking,stone engraving,leather marking, and coated surfaces marking. They are ideal for industrial metal engraving and batch production lines.
3. How Precise Do You Need to Engrave?
UV laser engravers deliver ultra-fine, 0.0019 mm micron-level detail.Choose UV if your work requires precision and clean finishes. Such as tiny text, intricate designs, or clean jewelry marking.The advanced motion control algorithm of the Omni X improves rotating engravings and photo engraving for more detailed and smoother results.
4. Do you prioritize speed, or precision?
Fiber laser engravers offer high power (ComMarker Titan up to hundreds of watts) and fast processing speeds, ideal for high-volume jobs and metal cutting.
UV laser engravers typically stay under 12W and are slightly slower, but they balance speed with exceptional precision.
5. Still Not Sure Which Laser Engraving machine Fits Your Needs?
Choose a Fiber Laser Engraver(ComMarker B4,B6,B6 MOPA,Titan) if you mainly work with metals, plastics, or coated surfaces, need need high efficiency for batch production, and want durable results.
Common uses: metal medals, keychains, engraved pens, and industrial metal parts.
Choose a UV Laser Engraver(ComMarker Omni 1, Omni X, Omni XE) if you often work with glass, crystal, wood, jewelry, or electronic s, need high precision and delicate finishes, even in small batches.
Common uses: glass cups, crystal awards,leather wallets, wooden keepsakes, and jewelry markings.
