Pensando en comprar un grabador láser, pero no estoy seguro de qué tipo se adapta mejor a sus necesidades? No estas solo. Many makers, aficionados, and small business owners face this question when deciding between a UV laser engraver and a fiber laser engraver.
In this hands-on comparison, I tested both types of laser engravers on a wide range of materials—metal, plástica, vaso, piedra, madera, textiles—and logged the real-world differences. If you want to understand what a UV laser can do that a fiber laser can’t (y viceversa), keep reading.
What’s the Real Difference Between a UV and a Fiber Laser Engraver?
Both UV and fiber laser engravers use high-speed galvo systems to create precise marks. But the laser wavelength is where things get interesting:
- Láseres de fibra operate in the infrared spectrum, relying on heat. They’re ideal for deep metal engravings and rust removal but can damage sensitive materials.
- grabadores láser ultravioleta usar ultraviolet light that reacts photochemically—so instead of burning, they mark by breaking molecular bonds. This allows them to engrave delicate materials like glass, el plastico, or textiles without cracking, pandeo, o ardiendo.
If your projects include a variety of materials beyond just metal, this difference matters a lot.
Laser Engraver Showdown: Head-to-Head Testing by Material
Engraving Metal Business Cards
Láser de fibra: Profundo, de alto contraste, rápido. Great for production.
Láser ultravioleta: Crisp but shallow engraving, not suited for cutting.
Veredicto: Fiber laser engraver wins for metal card production.
Raw Metals – Aluminum, Latón, Cobre, Acero inoxidable
Láser de fibra: Excels across all types—deep engraving, 3D effects, even color (if you’re using a MOPA fiber laser).
Láser ultravioleta: Can engrave, but marks are shallower and fewer visual effects.
Veredicto: For industrial-level durability or color effects, fiber is unmatched.
Plastics and Acrylics
Láser ultravioleta: This is where it shines. Whether it’s black, claro, de colores, or even transparent acrylic—UV delivers precise, limpio, high-contrast results without melting.
Láser de fibra: Works well on some plastics but tends to burn or melt the surface. Not reliable across all materials.
Veredicto: Laser engraver for plastic? UV is the clear winner.
Glass Engraving and Cutting
Láser ultravioleta: Engraves cleanly with a frosted effect, no cracking. Can even do subsurface engraving and cut thin glass—perfect for custom glassware or awards.
Láser de fibra: Simply can’t engrave glass without a workaround (p.ej. marking spray or tape), and results are usually poor.
Veredicto: If you want to do grabado de vidrio, a UV laser engraver is the only real choice.
Engraving Wood
Láser ultravioleta: Precise and clean engravings with no smoke stains. Ideal for fine detail work like signs or jewelry boxes.
Láser de fibra: Struggles. Most fiber engravers won’t even leave a mark on wood.
Veredicto: Usar un UV laser engraver for wood, especially if contrast isn’t your top priority.
Engraving Textiles & Cuero
Láser ultravioleta: Ablates the surface dye, leaving soft fabrics intact. Works great on denim, poliéster, and even microfiber towels.
Láser de fibra: May not mark at all, or might melt/burn the fabric.
Veredicto: UV is best for engraving textiles and gives better results on leather too—no burn marks.
Engraving Stone
Láser de fibra: Can go deep and fast—good for awards, stone coasters, etc..
Láser ultravioleta: Can engrave some types, but marks are shallower and less consistent.
Veredicto: Fiber laser is better for engraving on stone unless extreme detail is required.
Specialty Use Cases
- Rust Removal: Fiber laser wins hands down.
- PCB Prototyping: Fiber laser’s precision and power make it ideal for etching and drilling copper.
- Rubber Stamp Making: UV laser offers cleaner results with crisp detail.
- Engraving Ceramic Cups: UV laser removes paint cleanly with no charring.
- Engraving Cardboard or Leaves: UV laser handles these fragile materials effortlessly.

Choosing the Right Laser Engraver for Your Projects
There is no universal “best” laser engraver—it comes down to your materials, projects, and business goals.
Para mí, running both a UV and fiber laser engraver side-by-side lets me cover everything from custom tumblers and cutting boards to serial-coded metal parts and glass ornaments.
If you’re just starting out and want a versatile tool for el plastico, vaso, and detailed engraving, go with a grabador láser ultravioleta.
If your projects demand metal engraving at production scale, a grabador láser de fibra is your best bet.
