xtool-f1 Ultra: Answers to the 7 Questions I Wish I'd Asked Before Buying

When I unboxed my xtool-f1 Ultra 20W, I thought I'd done all the homework. I'd read the specs. I'd watched the reviews. I felt ready.

I wasn't.

18 months later, after burning through more test materials than I care to admit and ruining a handful of paying projects, these are the questions I wish someone had answered honestly—not just the marketing version.

1. What exactly is the laser type in the xtool-f1 Ultra, and why should I care?

The xtool-f1 Ultra uses a dual-laser system that combines a 20W fiber laser (1064nm wavelength) with a 20W diode laser (455nm wavelength). It's not a hybrid in the sense of being a single beam—it's two independent laser modules sharing one motion system and enclosure.

Why this matters: fiber lasers are great for metals (especially deep engraving on stainless steel, aluminum, and brass) and some plastics. Diode lasers are better for wood, leather, and acrylic (though we'll get into the acrylic caveat). With the xtool-f1, you physically switch between the two modules depending on the material.

Here's where I messed up: I assumed 'dual laser' meant one laser could do everything. It doesn't. You choose the right tool for the material. Trying to cut wood with the fiber laser is a waste of time—it'll barely mark it. And using the diode laser on steel? Not happening.

(Source: xtool official spec sheet for the F1 Ultra, which lists both modules as separate components.)

2. What are the best xtool-f1 Ultra acrylic cutting settings?

This is the question I see constantly, and the honest answer is: it depends entirely on the acrylic.

Cast acrylic (often sold as plexiglass) can be laser-cut beautifully with the diode laser module. Extruded acrylic? It's harder to cut cleanly and often leaves frosted edges. I learned this the hard way on a batch of display stands (about 40 pieces) where I used the wrong settings and ended up with edges that looked like frosted glass instead of clear.

Here's a starting point I've verified for 3mm clear cast acrylic on the diode module:

• Speed: 50-60 mm/s
• Power: 80-100%
• Passes: 3-5 (depending on cleanliness of the cut)
• Air assist: ON (critical—more on this in a moment)

But you must test on a scrap piece first. Every batch of acrylic behaves slightly differently. What worked perfectly on a sheet from McMaster-Carr might fail on a sheet from a local supplier.

3. Is the xtool-f1 Ultra really a 'compact' laser engraver?

Yes and no.

The footprint of the xtool-f1 base unit is genuinely compact—it's about the size of a large gaming console. It'll sit on a desk without dominating the room. If space is your primary constraint, it's among the smallest dual-laser systems I've seen (and I've looked at a lot, including the LaserPecker LP5).

But.

Compact doesn't mean simple. You still need space for:

• Ventilation (exhaust tubing to a window, ideally)
• Air assist pump and tubing
• Rotary attachment (if you want to engrave cylindrical items)
• Material storage

Also, the work area (roughly 155 x 160 mm for the diode, about 110 x 110 mm for the fiber) is small. You're not cutting large signs or engraving big panels on this machine. It's for small items—dog tags, pens, phone cases, small trophies. In my first month, I tried to engrave a 12-inch wooden plaque and quickly discovered it wouldn't fit. That was a $25 lesson in measuring twice.

So yes, the compact laser engraver label is true, but it's a desktop tool for small projects, not a production machine.

4. Do I need a 'cutting machine blade' for use with the xtool-f1?

This question comes from a very understandable confusion. Many people search for 'cutting machine blade' because they're coming from a background of vinyl cutters or blade-based plotters (like Cricut or Silhouette). The xtool-f1 is a laser system—it uses focused light, not a physical blade.

You don't need a blade for the laser. But you might want one in addition.

For example, I sometimes use a combination approach: cut the outline of a design on a vinyl cutter (with a blade) to create a stencil, then use the xtool-f1 to fill the engraving. It's not common, but it highlights the versatility. Don't expect the xtool-f1 to replace a blade cutter—they serve different purposes.

If you're looking for a purely laser-based solution, ignore blade options entirely. The xtool-f1 is a laser engraver and cutter, and that's all it does.

5. What does air assist do for laser engraving on the xtool-f1?

To be blunt: air assist is not optional for many materials on the xtool-f1, especially for cutting.

Air assist blows a stream of compressed air onto the cutting/engraving area. This does three things:

1. Removes smoke and debris from the laser's path, reducing flame-ups and burn marks.
2. Blows away gas that builds up during cutting (especially important for acrylic), which can cause a 'stall' in the cut.
3. Cools the material near the cut line, reducing heat-affected zones (HAZ).

I tried cutting 3mm plywood without air assist on my third project. The result was charred edges so bad I had to scrap the entire piece. Adding air assist reduced the charring by probably 80% on the next attempt.

The xtool-f1 comes with a basic air assist pump in some kits, but I'd recommend upgrading if you cut frequently. The stock pump works, but it's not powerful. I've since swapped to a small whisper-quiet compressor (circa 2023), and the difference is significant—cleaner cuts, less mess, far fewer fire alarms.

For a quick rule of thumb: if you're cutting any organic material (wood, paper, leather, fabric) or acrylic, use air assist. Engraving metals? Less critical, but still helpful for keeping the lens clean.

6. What's the biggest mistake I've seen with the xtool-f1 Ultra?

The one that makes me wince: using the wrong laser module at full power on thin materials without testing.

In August 2023, I decided to engrave a batch of 50 anodized aluminum keychains. The fiber laser module is perfect for this—great contrast, fast speed. But I set the power too high on the first run because I didn't bother to do a material test. The laser blew through the anodized coating and into the bare aluminum, leaving an ugly, washed-out mark. Worse, the heat discolored the surrounding area.

50 pieces, essentially ruined. That was an $85 mistake in materials plus about 3 hours of wasted laser time. I would've saved it all with a 5-minute test on a single piece.

Moral: test on scrap every time. Every. Time.

7. Is the xtool-f1 Ultra the 'best' compact laser engraver?

I'll give you the honest answer I wish someone had given me: it's the best for a specific set of use cases.

Best for you if:

• You need both fiber and diode capability in one machine (saves desk space).
• Your projects are small—engraving, marking, and light cutting on materials up to about 5mm.
• You value precision over speed (the xtool-f1 is solid here).
• You're willing to invest time in learning the dual-laser workflow.

Not the best if:

• You primarily want to cut large wood sheets.
• You need very high throughput for production work.
• You're on a strict budget (the xtool-f1 Ultra is a premium-priced machine—circa January 2025, it's around $1,500+, depending on accessories).
• You prefer a single, simple laser system that does one thing well.

I use mine for small-batch production (engraved metal badges, custom acrylic awards) and prototyping. For that, it's excellent. For a woodworking shop cutting large panels? Not the right tool. Don't let anyone tell you it can do everything—it can't. But what it does, it does well.
