Can the xTool S1 Cut Clear Acrylic? A Procurement Manager's Honest FAQ

Your xTool S1 Questions, Answered Honestly

Hey there. I manage purchasing for a 150-person manufacturing company. Basically, I'm the one who buys everything from office supplies to small workshop equipment, dealing with about a dozen vendors and a budget that's... well, let's just say I have to justify every dollar. When our prototyping team started asking about desktop laser engravers, the xTool S1 kept coming up. So, I did what I do: I dug in. Here are the real questions I asked (and the answers I found) before we made a call.

This isn't a sales pitch. It's a breakdown from someone who needs gear that works, doesn't break the bank, and won't make me look bad to the finance team.

1. Can the xTool S1 actually cut clear acrylic?

Yes, but with a major caveat you need to know. The xTool S1, especially with the 40W laser module, can cut clear acrylic. The laser wavelength—that 10,600nm CO2 laser—is actually really good for it.

Here's the insider bit most product pages gloss over: You get a polished, flame-polished edge on clear acrylic, which looks fantastic. It's one of the real strengths of a CO2 laser versus a diode laser for this material.

But—and this is a big but—you must use the right kind of acrylic. You need cast acrylic, not extruded acrylic. Extruded acrylic melts differently and can leave you with messy, bubbly edges. I learned this the hard way on a test run. We bought a cheap sheet from the local big-box store (probably extruded), and the cut was awful. Switched to a known cast acrylic supplier, and it was like night and day. So the machine can do it, but your material choice is 50% of the battle.

2. What's the deal with the swappable laser modules? Is that a gimmick?

Honestly, I thought it might be at first. But no, it's pretty much the S1's core feature and, for a small business, its biggest advantage.

You start with one module—say, the 20W CO2 for detailed engraving on wood and acrylic. Then, if you suddenly get a project needing to mark metal or dark plastics, you buy the 40W diode module (or the IR module) and swap it in. It takes maybe 5 minutes. You're not buying a whole new machine.

From a procurement perspective, this is huge. It turns a fixed capital expense into a more scalable one. Instead of asking for $5,000 for a new specialized machine, I can justify a $1,200 module upgrade to expand capabilities. That's an easier conversation with the VP of Ops. It future-proofs the initial investment.

3. How well does it engrave leather? Can you ruin a project?

It engraves leather beautifully for things like custom wallets, belts, or key fobs. The CO2 laser gives you a clean, dark mark without cutting through.

The pitfall here is vegetable-tanned leather vs. chrome-tanned leather. You want vegetable-tanned. Chrome-tanned leather can release toxic chlorine gas when lasered. Never, ever engrave chrome-tanned leather. It's a health hazard and will damage your machine. This is non-negotiable. Always check with your leather supplier.

The other thing? Test your settings on a scrap piece first. Power and speed affect the darkness and depth. It took us a few tries to get a deep, consistent mark without any scorching on the edges. A little patience here saves a pricey piece of leather.

4. Is "desktop" size a pro or a con for a small workshop?

It's both, honestly. Let me break it down.

Pro (The big one): You don't need a dedicated industrial space or special ventilation installs upfront. We rolled it into a corner of our prototyping lab with the optional air assist and an inline fan venting out a window. The footprint is maybe like a large printer. For a startup or a small shop without a full machine shop, this is the difference between "maybe" and "yes."

Con (The trade-off): The work area is smaller. The S1's bed is about 19" x 12". You're not cutting full 4x8 sheets. You're cutting parts from a smaller sheet you load in. For our needs—prototypes, custom jigs, small batch signage—it's fine. If you're doing production runs of large panels, you'll hit a bottleneck. You have to be realistic about your project size.

5. What won't it do? What are the brand's own limits?

This is the most important question. Based on my research and the brand's own specs, here's where you draw the line:

• It won't cut thick, dense metals. You can engrave coated or anodized metal with the right module, but you're not cutting through 1/4" steel. That's for industrial fiber lasers. Don't expect it.
• Cut speed and depth on hardwoods are limited. It'll cut 1/4" birch plywood nicely. It'll struggle with 1/2" oak. It's about managing expectations. It's a desktop tool, not a production floor beast.
• You can't cut or engrave PVC or vinyl. These materials release hydrochloric gas when lasered, which is terrible for the machine and your lungs. This is a standard safety rule for all CO2 lasers, not just xTool.

The brand is actually pretty clear about this stuff if you read the fine print. They don't claim it's an industrial machine. That honesty is a point in their favor from where I sit.

6. Bottom line: When does the xTool S1 make sense for a business purchase?

Let me put it in my terms. The xTool S1 makes financial and logistical sense when:

• Your needs are diverse but low-to-medium volume (acrylic signs one week, leather tags the next, wood prototypes the week after).
• Space and upfront installation budget are real constraints.
• You need a gateway into laser processing without a $15k+ commitment. The modularity lets you grow into new applications.
• Your material thickness is generally under 1/2" for woods and plastics.

It doesn't make sense if you have a single, high-volume material (like only cutting 1/2" acrylic all day) or need to process full-sized sheets. At that point, you're looking at a bigger, more powerful machine, and the economics change.

For us, it filled a specific gap. It wasn't about replacing our CNC or outsourcing. It was about bringing quick, custom, small-scale fabrication in-house on a reasonable budget. And so far, it's done that. Just know what you're buying—and what you're not.
