xTool F1 Ultra: Honest Guide for Acrylic Cutting, Color Engraving & Beginners

In 2020, I bought my first laser engraver — a cheap diode machine I was convinced could handle everything. Metal tags? Sure. Acrylic keychains? No problem. Engraved cutting boards? Easy. Three months later, I was the owner of roughly $800 worth of ruined materials and one anodized aluminum sheet that looked like it had lost a fight with a blowtorch.

The tool has to match the job. Full stop.

I run a small custom engraving shop in Melbourne, Australia. We take on signage, dog tags, trophy plaques, corporate giveaways, and the occasional desperate rush order. Over five years, I've personally made 14 significant mistakes — totaling about $4,800 in wasted materials, redoes, and lost client trust. This article is the checklist I wish I'd had before I ever considered the xTool F1 Ultra.

Why "Best Laser Engraver" Is the Wrong Question

The thing most reviews skip is simple: the right laser engraver depends on what you actually make. A machine that engraves stainless steel beautifully can be painfully slow at cutting thick acrylic. A machine that crushes paper crafts might not even leave a mark on bare aluminum.

So before you compare specs, ask a better question: which scenario am I in?

Based on the questions we get from other small shop owners, most people fall into one of these four situations:

1. You need to engrave metal — coins, tags, tools, jewelry
2. You need to cut acrylic — signage, displays, keychains
3. You want color engraving effects — the blue/gold/rainbow looks on metal
4. You're a beginner — cutting paper and wood, building a hobby or side hustle

The F1 Ultra is genuinely capable in all four areas. But "capable" means different things depending on your situation. Let's go through them one by one — including the ways I've personally screwed each one up.

Scenario 1: You Engrave Metal — Coins, Tags, Tools

If your work involves bare metal, this is where the F1 Ultra earns its keep before you even unpack it.

Here's why: the F1 Ultra has two lasers — a 20W fiber source and a diode source. The fiber laser is the one that matters for metal. It can mark stainless steel, aluminum, titanium, and even coated metals directly, without the marking sprays or pastes that diode-only machines rely on.

That's a bigger deal than it sounds. I learned this the hard way.

In 2021, I bought a diode-only machine specifically to save money. My first real job with it was a batch of 40 stainless steel dog tags for a veterinary clinic in Brunswick. What should have been a straightforward engraving job turned out impossible — the diode laser couldn't touch bare metal. I spent a weekend trying every trick in the book: marking spray, black paint, even a layer of wet paper (don't ask). The tags came out patchy and embarrassing. I missed the deadline, ate the cost, and lost the account.

The F1 Ultra's fiber laser handles bare metal directly. No coating. No praying. You clamp the tag, focus, engrave, done.

One thing worth noting if you're reading this from Australia: the voltage and plug are standard here (240V), and xTool ships to Australia from local warehouses — we got our unit in about eight days. But lead times fluctuate, so check current stock levels before you rely on a specific arrival date.

Scenario 2: You Cut Acrylic — Signage, Displays, Keychains

This is the question I get most often: can the xTool F1 Ultra cut acrylic?

Yes. With a qualification that matters: thickness is the whole game.

For thin acrylic — 1/8 inch (3mm) and under — the F1 Ultra is genuinely capable. We've cut hundreds of small keychains, display stands, and kitchen tidbits using the diode laser. The edges come out clean enough that a quick flame polish makes them look store-bought. It's slower than a CO2 laser, but it's consistent and hands-off.

For thick acrylic — 1/4 inch (6mm) and above — the story changes. The diode laser needs multiple passes, the edges start to melt and take on that frosted-white look, and cutting time multiplies. It's not impossible; it's just not ideal. If you're regularly cutting thick sheet for signage, a CO2 machine is the right tool.

My acrylic disaster: in March 2024, we took a rush order for 12 acrylic display stands — 6mm thick, engraved logo, due Friday. I said yes, overconfident from our success with thin acrylic. The first two stands took 15 minutes each and looked fine. By stand four, the edges were fuzzy and the corners had started to crack. I had to call the client and ask if 3mm would work — which was a partial lie, because they were in a bind too. They accepted the 3mm. I stayed up until 1am on Thursday fixing the engravings.

What to expect: the F1 Ultra is a solid acrylic cutter for thin stock, and a "workable but fussy" option for thick stock. Know which one you're buying it for.

Scenario 3: xTool F1 Ultra Color Engraving Reality

Color engraving on metal is one of the most impressive things the F1 Ultra can do. It's also one of the most oversold features on YouTube.

Here's how it actually works: the fiber laser heats the metal surface just enough to create a thin oxide layer. The thickness of that layer shifts the color you see — blues, golds, purples, reddish rainbows. It's physics, not magic.

But — and this is important — it's a process, not a preset.

In November 2023, I watched a demo video of rainbow engraving on stainless steel, loaded the same settings into our machine, and pressed start. The tag came out a uniform charcoal brown with a patchy blue edge. It looked less "premium" and more "left in the barbecue."

What I learned after about 30 test runs: color engraving depends on power, speed, frequency, frequency, and the exact metal composition. You need to dial in your own settings for your specific material. We built a reference card with about 25 power/speed combinations documented, and we use that to match the color our clients ask for.

What to expect: once dialed in, color engraving is repeatable and genuinely profitable — we charge 40–50% more for colored tags compared to standard engraved ones. But budget a solid week of testing before you offer it to paying customers.

Scenario 4: You're a Beginner — Paper, Wood, and Crafts

Now the honest part. If you're just starting out, I need to tell you something that might not be what you want to hear:

The F1 Ultra is probably overkill for you.

Laser cut paper and light wood crafts don't need a 20W dual-laser workstation. A quality budget diode laser in the $400–700 range can handle cardstock, birch plywood, and leather. If your plan is Etsy projects and weekend gifts, that's the smarter place to start.

I'll go further. In April 2022, we bought an ultra-cheap machine specifically for a paper-cutting job — 200 wedding invitations that needed detailed cutouts. It worked for the first 80. Then it failed with a firmware error, the manufacturer had zero local support in Australia, and I spent three weeks sourcing replacement parts. A wedding order. Late. Because I saved $400 on the machine.

That's where the "affordable" argument falls apart: if you're taking orders from real people with real deadlines, a machine that might work is a liability. What you're actually buying with a more reliable, well-supported machine is certainty.

So here's my framework for laser engravers for beginners:

• Hobbyist, flexible timelines: buy cheap, learn the basics, upgrade when you hit a wall.
• Side hustle with paying clients: buy something dependable. It's cheaper than refunds and apologies.

How to Know Which Category You're In

Still torn? Here are the three questions I ask people who email me:

1. What's your most common material? If it's bare metal, the F1 Ultra is justified. If it's paper and wood, a cheaper machine works fine.
2. Do you have deadlines that actually matter? Not just "it'd be nice to finish this week" — real client or event deadlines. If yes, reliability is a business expense, not a luxury.
3. Will you grow into this? If you're planning color engraving, metal marking, or rotary engraving of tumblers within the next year, buying one versatile machine now is smarter than buying a cheap one now and a second machine later.

The Bottom Line: Certainty Is Worth Paying For

For years, I assumed the premium you pay for a brand like xTool was mostly marketing. Then I saw the operational reality of my own mistakes. When a client needs 40 engraved signs by Friday, a machine that works out of the box isn't a luxury — it's the only version of "cheap" that makes sense.

The F1 Ultra isn't free of shortfalls: thick acrylic struggles, color engraving requires setup time, and the price is real. Desktop dual-laser machines like this typically sit in the $1,500–$2,500 range (based on publicly listed prices on xtool.com, March 2025 — verify current rates). But for metal marking, thin acrylic production, and color work, it has earned its place in our shop.

These experiences are accurate as of March 2025. The laser engraving machine market — in Australia and globally — moves fast, and xTool may update the F1 Ultra or release newer models. Check current specs, pricing, and local stock on the official xTool site before you buy.

And when you do choose — test your machine, document your settings, and never promise a client anything you haven't tested yourself. That's the lesson that cost me $4,800 to learn.
