Can the Xtool S1 Cut Acrylic? Yes, But Here's What 2 Years of Mistakes Taught Me

This Isn't a Spec Sheet – It's a Confession

I'm a guy who runs a small workshop making custom signs and gifts. I've been handling order fulfillment for about 3 years now. In my first year (2022), I made some spectacular mistakes with my Xtool S1 laser engraver. I'm talking about wasted acrylic sheets, ruined pieces, and a lot of frustration.

So, when I say I've personally burned through maybe $600 worth of materials learning what this machine can and can't do (especially with acrylic), I mean it. This article is everything I wish someone had told me upfront. Forget the marketing fluff – here’s the real-world answer to your biggest questions.

Can the Xtool S1 Actually Cut Acrylic?

Short answer: Yes, but only certain types.

The key distinction you need to know is between cast acrylic and extruded acrylic. The Xtool S1, particularly with the 20W and 40W laser modules, is fantastic for cutting cast acrylic. I cut 3mm cast acrylic all the time for keychains and small signage, and it leaves a beautifully polished, flame-polished edge. It's one of the best things about this machine.

But extruded acrylic? That's a different story. It tends to crack and leave a frosted, rough edge because the laser energy affects the internal stresses differently. I learned this the hard way. In September 2022, I ordered $150 worth of the wrong acrylic sheets for a bulk order of 50 award plaques. Checked it myself, approved it, processed it. Every single piece had micro-cracks. $150 wasted plus a 1-week delay. Lesson learned: always ask for 'cast' acrylic.

If you're working with thicker acrylic (say, 5mm or more), you'll need the 40W module and multiple passes. The 20W module will cut 3mm in one pass, but 5mm might take 2-3 passes. Don't expect to cut 10mm acrylic like a pro-grade industrial laser – it's not designed for that.

(Based on my own Xtool S1 with 20W and 40W modules, tested on various cast acrylic samples over 2023-2024. Your results may vary with material brands and settings.)

What Are the Real Xtool S1 Laser Engraver Specs I Should Care About?

Look, you can find the official specs on their website. I'm not gonna reprint the manual here. Let me tell you what the numbers actually mean for your work:

• Work Area: 432 x 406 mm. It's bigger than you think. I've fit full-sized laptop sleeves and large cutting boards easily. Perfect for small business work.
• Laser Power (20W vs 40W): The 20W module is the workhorse for engraving and thin materials (up to 3-4mm wood/acrylic). The 40W module is your upgrade for cutting thicker stuff (up to 8-10mm wood, 5-6mm cast acrylic). I'd argue the 40W is worth it if you plan on cutting thicker projects regularly.
• Laser Module Swap: This is the S1's secret weapon. It's genuinely tool-free. I can swap from the 20W to the 40W in under 30 seconds. If you do a mix of fine engraving and heavy cutting, this is a game-changer.
• Rotary Tool: It works way better than I expected. For cylindrical engraving (cups, bottles, wine glasses), the included rotary attachment is solid. Just make sure your item is truly cylindrical.
• Material Compatibility: It officially runs wood, acrylic, leather, glass, and metal (with spray). I've also had good luck with anodized aluminum (engraving off the coating) and slate coasters. The software profiles for 'Xtool' materials are pretty accurate, but I always do a small test first.

The surprise wasn't the power of the laser – it was how reliable the whole system was once I understood the material limits. No random shutdowns, consistent cuts. That's the trust factor you need for production work.

Are Laser Cutters Good for Schools? (from a Hobbyist-Turned-Educator's View)

Absolutely. Here's why, from personal experience helping a local high school's maker club:

1. Safety is manageable. The Xtool S1 has an enclosed design with a safety interlock. The school can lock the lid and control access with a key. It's not a toy, but it's way safer than an open-frame diode laser. We used the 20W module for the students because it's more than enough for cardboard, wood, and thin acrylic projects.
2. It teaches real-world skills. Design software, material properties, vector vs. raster, kerf settings – this is practical CAD/CAM knowledge. My clients who have kids using 3D printers and laser cutters are learning problem-solving, not just memorizing facts.
3. It's robust for a classroom. I've seen the S1 at the school; it's built with a metal frame and feels solid. They've had it for 6 months, and it's held up to dozens of students messing with it. No issues.
4. Instant gratification. That's the killer feature for kids. Design something in 15 minutes, hit print, and 5 minutes later you have a physical object. The 'wow' factor is immediate.

One thing I'd recommend for schools: stick with the 20W module initially. It's powerful enough for 90% of projects and has a lower learning curve for material settings. The 40W module can be a 'pro' upgrade for the teacher or advanced students.

What About Laser Cutting Acrylic (Akrilik) for Small Orders?

This is where the Xtool S1 shines for small businesses. I get where you're coming from. When I started, vendors wanted minimums of 100 pieces for laser-cut acrylic keychains. With the Xtool S1, I can do a batch of 10 custom keychains for a local business, or a single prototype for a client testing a design.

I once had a client who needed a 'test' run of 5 custom acrylic cake toppers. The big shops quoted $150 setup fees. I did them on the Xtool S1 with the 20W module in about an hour. Cost me maybe $5 in materials. The client was thrilled and placed a follow-up order for 200 units. That $5 small order turned into a $2,000 repeat client.

Small doesn't mean unimportant – it means potential. The Xtool S1 lets you treat every small request seriously without needing a massive upfront investment. If you're doing 'laser cutting akrilik' for small jobs, this machine is perfect.

Is the Xtool S1 Good for Wood Engraving?

Yes, it's excellent. This is probably what I use it for most. I make custom cutting boards, signs, and coasters from various woods.

The 20W module engraves wonderfully on:

• Birch and balsa (super clean, light contrast)
• Walnut (deep, dark engraving)
• Oak (needs a slightly slower speed, but great results)
• Bamboo (uneven surface, but the autofocus handles it OK)

For cutting wood, the 20W module will cut through 3mm plywood in one pass. The 40W module handles up to 8mm in one pass (sometimes 10mm, depending on wood density). I cut 6mm birch plywood for a recent custom jigsaw puzzle order of 50 kits. Used the 40W module, one pass, no issues. The edges were a bit charred, but that's normal for laser cutting wood – a quick sanding fixes it.

The surprise for me was how well it engraves dark wood. Many desktop lasers struggle to get a good contrast on dark surfaces, but the Xtool S1 does a solid job, especially at lower power settings. The autofocus system is a lifesaver for uneven surfaces like natural-edge slabs.

What's the One Mistake I See New Xtool S1 Users Make?

Assuming you don't need to calibrate the laser or test material settings. When I got my S1, I was so excited I loaded a 5mm piece of wood, picked the 'Xtool Wood' profile, and hit go. It didn't cut through. The profile was set for 3mm. That wasted a $4 piece of walnut.

Now, I always do a 'grid test' for every new material and thickness. I set different power and speed combinations, and run a small 2x2 inch grid. It takes 10 minutes, but saves hours of wasted material. The Xtool software has a built-in material test function – use it. I've never regretted the 10 minutes it takes to dial in a new material.

Final Honest Take (After All That)

The Xtool S1 isn't a magic box that cuts everything perfectly. It's a seriously capable desktop tool for cast acrylic, wood, leather, and glass. But it's not a replacement for an industrial CO2 laser for thick materials or production-scale runs. For a small business, a school, or a serious hobbyist, it's a fantastic investment.

My experience is based on about 200 orders and countless prototype tests over two years. If you're working with ultra-thick materials (over 10mm) or extruded acrylic, your experience might differ. But for the 90% of everyday engraving and cutting jobs, the S1 is more than up to the task.

Take it from someone who's lost $600+ to mistakes: test your materials, use cast acrylic, and don't be afraid to swap modules. If you keep your expectations realistic for its power level, you'll be making great stuff in no time.
