Quality Check: Can the xTool F1 Ultra Deliver on Those Coin Engraving Promises?

Look, I’m a bit of a skeptic. It’s my job. As a quality compliance manager, I’ve spent the last four years reviewing roughly 200+ unique deliverables annually—from packaging prototypes to signage samples. I’ve rejected more first-round submissions in 2024 than I care to admit, mostly because specs were off by a hair or materials weren’t up to standard. So when I first heard about the xTool F1 Ultra, a desktop machine boasting both a 20W fiber and a 20W diode laser in one unit, my first thought wasn't “cool tech.” It was “show me the proof.”

This isn’t a promotional piece. It’s the story of how I ran it through my own quality audit—and what I found when I did.

The Setup: Why a Dual Laser?

My company’s small creative department needed a way to prototype personalized gifts and small-batch product runs. We wanted to engrave metal keychains and tumblers, but also wanted the flexibility to mark glass awards and cut acrylic signage. Traditionally, that meant two separate machines: a pricey fiber laser for metals and a CO₂ or diode laser for organics. The xTool F1 Ultra promised to be the Swiss Army knife solution—a compact 3-in-1 that could handle both without needing two beds.

The key spec that caught my eye was the dual laser source configuration. Most desktop engravers are diode-only. The F1 Ultra’s hybrid approach combined a 20W blue diode laser (for wood, leather, acrylic) with a 20W fiber laser (for metal, plastic engraving, and deep marking). The compact desktop footprint and built-in rotary axis for glasses or bottles also checked a lot of boxes for a small shop with limited bench space.

The Rookie Mistake: Trusting the Marketing Specs

In my first year, I made the classic specification error: assumed 'standard' meant the same thing to every vendor. It cost me a $600 redo on a client’s prototype run. So for the F1 Ultra, I didn’t just read the product page. I actually downloaded the xTool software, built a test file for a high-detail coin, and decided to run a blind quality check.

I ordered a batch of 25 blank stainless steel coins—the kind used for challenge coins or corporate gifts—along with a slate coaster and a piece of clear acrylic. My goal was simple: see if the machine could deliver consistent, high-contrast results without constant fiddling. No claims to be 'the fastest' or 'the best value,' but could it actually handle a multi-material workflow on a Tuesday afternoon?

The Process: Coin Engraving and Color Marks

Here’s where the story gets interesting. The first test was coin engraving. I selected a mark design with fine text and intricate borders—the kind of detail that shows mechanical slop. With the 20W fiber source, the F1 Ultra did not disappoint. The marks were crisp, consistent, and the contrast against the raw steel was excellent. After dialing in the focus height for the coin’s curvature (a step many users forget!), I ran ten coins consecutively. No failed starts, no misalignment. The process was surprisingly smooth.

The surprise wasn't the fiber laser performance. I expected that to work. The surprise was the diode laser’s performance on glass and slate. I ran a color engraving test on a black slate coaster using the diode source. The machine managed to produce a nice, frosted effect with good resolution. It wasn’t a photo-realistic print, but for text and simple logos, it looked professional. The rotary attachment also handled a glass tumbler without any wobble.

One thing that caught me off guard was the mobile aspect. The machine itself is quite portable—I’ve taken it to a maker space for a demo. To call it a mobile laser engraver feels accurate. It’s not something you’d toss in a backpack daily, but moving it between workstations or to a client meeting is totally feasible.

The Hidden Cost of 'Best Budget'

I’ve learned to ask 'what’s NOT included' before 'what’s the price.' This is where my transparency_trust viewpoint kicks in. The F1 Ultra’s listed price (around £850-£950 in the UK, depending on bundles) looks competitive for a 20W dual-laser device. But I noticed the base package didn’t include the rotary axis or the air assist unit. While you can engrave a glass without the rotary, it’s far less accurate. To get the full capability, you’re looking at an extra £150-£200 for the add-ons.

Is that a dealbreaker? Not necessarily. But I prefer vendors who list all fees upfront—even if the total looks higher—because it usually costs less in the end. When I see a vendor offering a 'complete starter pack' with all accessories, I trust that price more than one where you discover the rotary is sold separately after checkout.

“The vendor who lists all fees upfront—even if the total looks higher—usually costs less in the end.”

The Results: What Worked and What Didn’t

Here’s the raw data from my test (I kept a log, like any good inspector):

• Metal (Stainless Steel Coins): Excellent. High contrast, deep mark. Took about 3 minutes per coin for a detailed design. Speed set to 60% power. No issues with the fiber source.
• Glass (Tumbler via Rotary): Good. Frosted mark, consistent depth. Required a bit of trial and error with the focus settings for the curve. I did have to re-run one pass to make the text fully opaque.
• Slate (Coaster): Very good. Diode laser nailed the contrast. The laser engraving stone settings needed tweaking—starting with 80% power and 300mm/s speed gave a clean white mark.
• Acrylic (Cut): Adequate. The diode laser can cut thin acrylic (3mm) but the edges were slightly frosted. For cutting, a CO₂ laser is still superior. For engraving, this works.

The best part of this test? The software interface was intuitive. It’s XCS, xTool’s proprietary software, and it offered clear presets for different materials. For a beginner with this machine, that preloaded database is a huge help. It saved me from guessing the power settings for stone, which I would have probably gotten wrong.

Bottom Line: Is It the Best Budget Laser Engraver UK?

So, is the xTool F1 Ultra the best budget laser engraver in the UK? That depends on your definition of 'budget.' If you mean the cheapest machine on Amazon, no. But if you mean the best value for a specific set of capabilities—specifically metal engraving plus organic material handling in a small footprint—it’s a strong contender. For a small business making custom awards or personalized gifts, the dual laser source eliminates the need to buy two machines. That saves bench space and potentially money in the long run.

However, I do have one piece of advice for shoppers: don’t buy just the core unit. Factor in the rotary and the air assist pump from day one. If you’re buying this as a best budget laser engraver UK option, get the full package. It’s more transparent and you’ll end up with a more capable tool.

The biggest lesson from this quality audit? The machine is good—and I’m a tough grader. If you’re serious about adding metal marking to your workshop without breaking the bank on a standalone fiber unit, the xTool F1 Ultra deserves a look.
