Engraving stone is no longer the domain of chisels and sandblasters alone. In 2026, laser technology has become the go-to method for precision, speed, and scalability on stone surfaces—from marble coasters to granite memorials. But not all lasers are created equal, and choosing the right one depends on the type of stone, your project size, and your budget.

This guide walks you through the key decisions you need to make before investing in a laser engraver for stone in 2026.

Step 1: Pick the Right Laser Type—This Is Non-Negotiable

Fiber Lasers are the only reliable choice for engraving hard stones like granite or marble. They operate at a 1064nm wavelength, which is absorbed by the minerals in stone, creating high-contrast, permanent marks without needing fillers or coatings .

• CO₂ lasers can engrave softer stones like slate or ceramic tiles, but they struggle with granite. You’ll get shallow, dusty marks that lack contrast .
• Diode lasers are affordable and portable, but they lack the power and wavelength to engrave dense stone effectively. They’re only suitable for light etching on soft materials .

✅ Verdict: If you're working with granite, marble, or basalt, go fiber. For slate, ceramic, or soapstone, a high-wattage CO₂ (55W+) can work .

Step 2: Match Machine Style to Your Project Size

There are two main machine styles:

• Galvo systems (like the Monport 60W or OMTech Galvo) use mirrors to steer the beam, engraving in minutes—ideal for high-speed production .
• Gantry systems (like the OMTech 50W Station) move the laser head over a fixed stone, making them better for large or heavy pieces .

✅ Ask yourself: What’s the largest stone I’ll engrave in the next 2–3 years? Choose a machine that fits that size.

Step 3: Choose the Right Power Level

• 50W is the sweet spot for most users. It’s fast enough for production and powerful enough for deep, permanent engravings on granite .
• 20W is fine for small gifts or testing, but it’ll take multiple passes to get depth on hard stone .

Step 4: Consider Portability vs. Production

• Portable units like the LaserPecker LP5 or xTool F1 Ultra offer dual-laser systems (fiber + diode) and can run on battery power. Great for on-site engraving, pop-up events, or small studios .
• Stationary units are better for high-volume or large-format work, but require ventilation, space, and setup .

✅ Tip: If you’re engraving headstones or large tiles, skip the portable units. If you're doing custom pet memorials or coasters, portability is a huge plus.

Step 5: Don’t Forget Software, Safety, and Support

• Software: Look for compatibility with LightBurn or EZCAD2—industry standards for fiber lasers.
• Safety: Enclosed designs, air assist, and fume extraction are essential when engraving stone indoors.
• Support: Brands like Monport, OMTech, and xTool offer US-based support, tutorials, and active communities .

Final Decision Matrix: Which One Should You Buy?

Bottom Line

In 2026, fiber lasers dominate stone engraving, especially for granite and marble. Your choice should be guided by stone type, project size, and production volume. Don’t overbuy for hobby use—but don’t underpower for business growth. Choose a machine that matches your current needs and future ambitions, and you’ll be engraving stone like a pro from day one.
