The xTool F1 Cut Metal Test: What Our Quality Audit Revealed About 20W Dual-Laser Limits

The Metal Cutting Test: Did It Actually Cut Through?

This was the make-or-break question. The F1's fiber laser is rated for engraving and light cutting on thin metals. We set it to cut a 10mm x 10mm square on 0.8mm stainless steel using the recommended parameters: 20W power, 100% speed, 30 passes.

First pass: it engraved a visible line. By pass 15, the cut was about 0.3mm deep. At pass 30, the square popped out—barely. The edge had a slight burr and the cut dimension measured 10.12mm, which is within our tolerance (+/- 0.2mm) but not consistent with the ideal 10.0mm. I noted: cuts, but not production-ready for precision parts.

Next, we tried brass. After 40 passes on 1mm sheet, we had a partial cut. It needed manual snapping and clean-up. That's a reject in my book—if I can't guarantee repeatability, I can't sign off. The vendor claimed the F1 can "cut thin metals." Technically true. Practically? You'd better define "thin" as sub-0.5mm, and "cut" as score-and-snap.

The surprise was anodized aluminum. One pass at 70% power and 200mm/s speed removed the coating cleanly for high-contrast marking. That's not cutting, but for serial number engraving on aluminum parts? That's actually a sweet spot. For $800 worth of test materials, that one finding alone justified the evaluation.

Glass Engraving: The Settings That Saved a Batch

I wish I had tracked our glass failure rate more carefully over the years. What I can say anecdotally is that about 1 in 4 glass items breaks during diode laser engraving due to thermal shock. The F1's diode laser isn't CO2, so it doesn't interact with clear glass natively—you need a marking agent like CerMark or a coated surface.

We tested four scenarios:

1. Bare float glass with diode (20W, 500mm/s, 90% power) — zero mark, as expected.
2. Float glass with CerMark coating (same settings) — clean, white mark. Edge quality: acceptable.
3. Wine glass with rotary attachment and diode — slow, but consistent mark. Issue: the coating layer added noticeable haze.
4. Boroscope slide with fiber laser — 2W fiber, 5 passes, 10% power — surprisingly crisp mark, no coating needed.

The fiber laser on glass was the "experience override" moment. Everything I'd read said you must use a CO2 or diode for glass. Turns out, the 20W fiber can mark certain types of glass at low power quite well—if you're okay with a grayscale rather than a frosty white. The diode path works, but it's not "pure" engraving; it's coating removal with a visible marker.

I only fully believed the fiber option after ignoring a colleague's warning about thermal cracking. I ran 10 borosilicate slides at 15% power and 30% speed—and got zero cracks. The diode route? I lost one wine glass out of ten to thermal stress. Not terrible, but enough to matter on a 50,000-unit annual order.

The Hidden Costs of 'Versatile' Material Processing

Here's where the transparency trust viewpoint kicks in. The xTool F1 is marketed as a versatile dual-laser machine capable of handling hundreds of materials. True—but only if you invest in accessories and consumables. Let me be blunt:

• Rotary attachment: ~€199 extra. Necessary for cylinders like glasses and bottles. Not included.
• Air assist pump: ~€49 extra. Without it, wood and acrylic char heavily at higher power.
• Honeycomb worktable: ~€79 extra. For cutting thin materials without back-burning.
• CerMark spray: ~€40 per can. Glass engraving isn't free—you'll need coatings for clear materials.
• Fume extractor: ~€149 extra. The built-in fan helps, but for production runs, you need proper ventilation.

The base unit arrived at €1,999. By the time I added the tools to make it truly production-capable, the total was €2,515—a 26% premium. That's not a complaint; it's a reality. I've learned to ask "what's NOT included" before "what's the price." The vendor who lists all fees upfront—even if the total looks higher—usually costs less in the end.

To be fair, xTool's product page does mention these accessories. But it's buried in the "compatible items" section, not in the pricing breakdown. A more transparent approach would be to show an "all-in-one kit" price upfront. That builds trust.

What the F1 Can't Do (And Why That's Okay)

Hit 'order' on the F1 and immediately wondered: Did I make the right call for production? The two weeks until delivery were stressful. Didn't relax until we validated the first batch of anodized aluminum markers against customer spec.

That said, there are hard limits:

• No clean through-cut on metals thicker than 0.8mm. For sign making, that's fine—most architectural plates are 0.5mm aluminum. For structural parts, you need a dedicated fiber laser or waterjet.
• Limited speed for large-area engraving. At 200mm/s, the F1 covered a 200x200mm area in about 12 minutes. That's acceptable for low-volume customization but not for mass production. We compared it against a 30W CO2 laser—the CO2 was 3x faster for wood engraving.
• Software integration quirks. LightBurn works well, but the xTool software (XCS) has some rough edges—especially with dual-laser switching. During testing, we lost 2 hours troubleshooting a profile mismatch. That's not a dealbreaker, but it's worth budgeting setup time.

Granted, these limitations are expected for a desktop hybrid. The value isn't the speed—it's the certainty that you can handle a wide range of materials with one unit. For a small business that gets occasional orders for engraved brass plaques, glass awards, and wood signs, the F1 is a legitimate tool. You just need to know where its edges are.

The Verdict: Should You Buy an xTool F1 in 2025?

I don't have hard data on industry-wide defect rates for desktop lasers, but based on our 5 years of orders, my sense is that machines in this class have about a 15-20% "out of box fine-tune" rate—meaning they work, but need calibration or accessory investment before production-ready. The F1 fell right in that range. It runs well after initial setup. It's not a plug-and-play miracle, but it's not a lemon either.

If I were equipping a small production shop today, I'd buy the xTool F1 specifically for:

• Low-volume metal marking (serial numbers, logos on brass/aluminum)
• Glass awards with CerMark (10–20 pieces per week)
• Mixed-material prototyping where switching between lasers matters
• Quick turnaround jobs where you need one machine that does "okay" at many things

I'd skip it if you need:

• High-volume consistent cutting of metals
• Deep engraving on thick acrylic or hardwoods
• Zero learning curve—budget 8–12 hours for setup and calibration

The bottom line? The xTool F1 can cut thin metal—barely. It can engrave glass—with the right prep. It's versatile, not a specialist. And for many B2B users, that versatility is worth the premium. Just don't call it "the best laser engraving machine" in isolation. It's the best for a specific workflow. Know your workflow, and you'll know if the F1 fits.

As of May 2024, the pricing I referenced was accurate. Verify current specs and bundle pricing at xTool's official site—rates may have changed.
