Will laser engraving wear off?

Laser engraving looks permanent—but can it really last through daily wear, chemicals, or outdoor use?

Laser engraving made with the right machine and material is permanent. Deep laser marks, especially on metals, won’t fade or rub off unless the surface is physically destroyed.

If you're investing in laser marking for inventory control, branding, or traceability, it’s critical to understand what affects longevity—and what doesn’t. Let’s break down the myths and truths.

How long will laser engraving last?

Engraving a product is one thing. Making sure it stays readable is another.

Proper laser engraving, especially on metals with fiber lasers, can last the entire lifespan of the product—even in harsh environments like factories, warehouses, or outdoors.

What makes laser engraving so durable?

Laser engraving isn’t just ink or a coating. It changes the surface of the material.

At Kirin Laser, we work with wholesalers and OEM clients who need product ID codes, logos, or batch numbers that last through years of use. I once had a client in Germany ask, “Can this marking survive outdoor snow-clearing equipment?” With the right fiber laser settings, yes—it absolutely can.

Depth matters

When the laser cuts into the material, it creates a groove that won’t wash away. Compare that to surface printing, where abrasion removes the top layer. It’s like carving vs. painting.

Does laser engraving fade?

It depends on the material—and the method.

Engravings on bare metals using a fiber laser do not fade. But surface markings on plastics or coatings can wear down under heavy friction or chemicals.

Let’s get real about fading

I’ve worked with hundreds of clients who ask, “Will this still be visible after months of use?” Here’s how we break it down:

✅ Permanent or near-permanent:

• Stainless steel (deep engraved or annealed)
• Anodized aluminum (engraving removes color but stays readable)
• Brass, copper, titanium (deep engraving lasts)

⚠️ May fade over time:

• Coated metals (only if the laser doesn’t reach the base)
• Plastics (depends on type and depth)
• Painted surfaces (unless paint is fully removed)

✖️ Short-term marking:

• Painted glass
• Paper/cardboard
• Thin acrylics exposed to sun

A client in outdoor signage once said, “We used screen printing for years, but every summer we had to redo the labels.” After switching to a UV laser⁴ for color-changing marks on white plastics, their signage lasted three full seasons without replacement.

Do laser engravers wear out?

Machines, like anything mechanical, have lifespans. But the quality and design of the machine make a huge difference.

A well-built laser engraver—especially an industrial fiber or CO₂ model—can last over 100,000 hours. Maintenance, not replacement, is the key.

What wears out first?

Most laser engravers include three core components:

At Kirin Laser, we always remind customers: even the best machines require care. But it’s not rocket science. We include a preventative maintenance checklist for our clients that even non-technical staff can follow.

One of our U.S. distributors told me, “We’ve been running your 30W fiber machine for three years straight, 5 days a week—and we haven’t had to touch it. That’s unheard of compared to our old CO₂ system.”

Does laser engraving come off?

If it’s engraved correctly—no, it doesn’t come off. But if the wrong machine is used, or it’s only a surface mark, it might.

Laser engraving becomes part of the material. Only grinding or sanding it off will remove it. Surface laser marking on coatings or plastics may peel or fade, but true engraving stays.

Why do some marks disappear?

Here’s what we’ve seen:

• Coated metal + low power laser: only etches paint, not metal
• Plastic + too fast scan speed: shallow burn, easy to scratch off
• No cleaning before engraving: oils block full beam impact
• Wrong focus distance: beam spreads, loses intensity

One of our clients runs a tool rental shop. For years, he used stickers and inkjet barcodes—but customers scraped them off. “I lose track of who’s got what,” he told me.

We helped him switch to a Kirin Laser 50W fiber marker⁸. Now, the codes are permanently marked on every wrench, hammer, or saw. He told me, “This is the first time I feel in control of my inventory.”

That’s the kind of result we design for.

Conclusion

Laser engraving⁹ done right doesn’t fade, doesn’t rub off, and doesn’t wear out. But the key is using the right machine, right material, and the right process. At Kirin Laser, we believe in building systems that last—so our clients can mark once and trust it will stay. If you’re tired of labels that peel or ink that fades, maybe it’s time to try something permanent.
