The Bottom Line First
For a small business or workshop cutting and engraving acrylic up to about 1/4 inch (6mm) thick, the xtool S1 is a viable, cost-effective option—if you budget for the complete system and manage your expectations. It's not an industrial cutter, but it gets the job done for a fraction of the upfront cost. The real expense isn't just the machine; it's the exhaust system, materials, and your time to dial in settings.
Why You Can Trust This Breakdown
I'm the procurement manager for a 12-person custom signage and display company. I've managed our equipment and consumables budget (around $45,000 annually) for six years. I've negotiated with 20+ vendors for everything from industrial CNC routers to desktop vinyl cutters. Every purchase, every material cost, and every maintenance fee goes into our tracking system. So when I talk about total cost of ownership (TCO), I'm not guessing—I'm looking at spreadsheets.
In Q2 2024, I led the evaluation to add a smaller-format laser for prototyping and small-batch acrylic jobs, comparing options from Glowforge, xTool, and a used 60W CO2 machine. The S1 won on initial capital outlay and footprint. But here's the thing vendors don't always emphasize: the machine price is maybe 60% of your starting cost.
The Real Cost Breakdown: What's NOT in the Base Price
Most buyers focus on the sticker price of the laser and completely miss the ancillary costs that can add 30-50%. Let's get transparent.
1. The Mandatory Extras: Exhaust & Air Assist
You cannot run an S1 cutting acrylic without proper ventilation. The fumes are toxic and will coat everything in a sticky residue. The built-in fan isn't enough.
- Exhaust Solution: You need an external inline fan and ducting to vent outside. A decent setup will cost you $150-$300. I budgeted $225 for ours. This isn't optional; it's a health and safety requirement.
- Air Assist: The S1's air assist pump helps produce cleaner, flame-free cuts, especially on acrylic. It's pretty good, but for prolonged cutting, some users upgrade to a more powerful compressor for about $100-$200. We haven't needed to yet, but it's a known potential future cost.
So, right off the bat, add a minimum of $200 to your machine cost. That "desktop" machine just got a bit bigger.
2. Material Cost & The "Good Acrylic" Premium
This was my biggest learning curve. Not all acrylic is created equal for laser cutting.
"Cast acrylic cuts and engraves with a beautiful, flame-polished edge. Extruded acrylic is cheaper but tends to melt more, can produce less clean edges, and may emit more problematic fumes." – Common industry guidance from material suppliers like TAP Plastics.
We buy cast acrylic in small sheets specifically for the laser. It costs about 20-30% more than the extruded stuff from the big-box store. The "cheap" option resulted in a $120 batch of parts with rough, bubbly edges that were unsellable. A classic case of a low material cost creating a high rework cost.
Also, you'll waste material dialing in power and speed settings for different thicknesses. Factor in a 10-15% "learning and test cut" waste for your first few projects.
3. Time = Money: The Speed Trade-Off
This is the main trade-off versus an industrial laser. The S1, especially with the 20W module, is slow for cutting compared to a 100W+ machine.
Cutting through 1/4" (6mm) clear cast acrylic might take 2-3 passes at a slow speed. What does that mean in practice? A job that takes an industrial laser 5 minutes might take the S1 20-30 minutes. For prototyping or one-off gifts, that's fine. For batch production of 50 pieces, it's a bottleneck. You're trading capital cost for labor time. I calculate our machine's "hourly rate" based on its lease cost and power consumption, but the bigger cost is often the operator's time waiting for it to finish.
What It Does Exceptionally Well (And Where It Shines)
With the right setup, the S1 produces fantastically detailed engraving on acrylic. The diode laser is great for surface marking, creating frosted designs, or even doing shallow "deep engraves." The rotary tool attachment (an extra cost, but worth it) lets you engrave cylindrical acrylic objects like pens and bottles—something much harder on a flat-bed CO2 laser.
For cutting thinner acrylics (1/8" or 3mm) for model making, signage layers, or intricate ornaments, it's more than capable. The edge quality on cast acrylic is professional. We use it mostly for these kinds of jobs and for engraving, and for that purpose, it's paid for itself in about 8 months by letting us take on small jobs we'd otherwise have to outsource.
Transparent Limitations & When to Look Elsewhere
Honestly, if your business plan revolves around high-volume cutting of thick acrylic, save for a used 80W+ CO2 laser or a fiber laser for marking metals. The S1 will be too slow. Also, while you can cut colored acrylics, some pigments (especially reds) don't absorb the diode laser's wavelength as well, requiring even slower speeds or more passes.
The "modular" design is a pro and a con. Swapping from the 20W to 40W module isn't instant; it requires realignment. For us, sticking with one module for 95% of our work made sense. Don't buy both modules thinking you'll swap them daily.
Final Verdict for the Cost-Conscious
Here's my procurement policy-style conclusion:
The xTool S1 is a justifiable capital expense for a small shop doing mixed-material prototyping, light acrylic production, and detailed engraving. Your total startup budget should be: Machine + $200-$500 for exhaust/accessories + a 15% buffer for material learning waste.
It wins on upfront cost, space, and versatility. You lose on raw cutting speed for thick materials. For our needs—small batch acrylic work, wood engraving, and marking coated metals—it was the right call. Just go in with your eyes open to the full system cost. The vendor who's transparent about needing an exhaust fan is the one you can probably trust on the rest.
