Real talk: the xTool S1 wasn't the cheapest laser engraver we priced. In my opinion, it was still the right one to order. I'd sign the same PO again today, and the reason has less to do with watts than with transparency.
I run purchasing for a 16-person product-development company. I manage roughly $200,000 a year in vendor spend across 9 suppliers, and I handle everything from prototype tooling to office supplies. I'm not a laser engineer. I won't pretend to be one. What I can tell you is what I've learned as the person who signs the paperwork, watches the internal users, and reconciles invoices.
When I took over purchasing in 2020, the first equipment request I processed was a link to a fiber laser welder for sale. The team actually needed metal tags engraved. A welder. It took two Zoom calls to figure out the real requirement. That experience taught me to ask 'what are you trying to make?' before asking 'what do you want to buy?'
It took me four years and about 60 equipment-related purchases to understand that the price you see is not the price you pay.
The vendor who lists all fees upfront—even if the total looks higher—usually costs less in the end.
That's become my rule. For the xTool S1, the rule actually held up.
Transparent Configuration Is the Real Feature
When we decided to buy a desktop laser, I asked our shop manager to spec a machine that could handle our usual mix: acrylic prototypes, wood signs, leather patches, glass awards, and occasional stone engraving. He kept coming back with 'can it engrave rocks?' because customers asked for slate coasters and river-stone gifts. So yes, laser engraving rocks was on the requirement list.
The xTool S1 engraver looked like a fit because its configurable module system is listed clearly on the product page. You choose a 10W, 20W, or 40W diode laser module. You can add the xTool S1 2W IR laser module for metal marking. Then you add the rotary bundle, air assist, honeycomb panels, and enclosure. Each item has a price. That's how a PO should work.
Why does this matter? Because the alternative is a bare machine with a low headline price and six 'required accessories' in the cart. By the time you add a chiller, fume extraction, proper ventilation, and the missing rotary, the quote is 30% higher than it looked. I'd rather see that 30% before I commit.
How I Evaluate Any Laser Quote
After the $2,400 invoice mess, I created a simple checklist. It isn't complicated, but it has saved me from more than one fast-talking sales call:
- Does the quote include every accessory needed to run the intended job?
- Can I get a downloadable spec sheet without giving my email to three sales reps?
- Is the support team willing to answer 'what's not included?'
- Does the vendor accept a PO and issue a proper invoice?
The xTool S1 scored well on all four. Other lasers scored better on watt-per-dollar. But watt-per-dollar doesn't help when the machine arrives without the rotary that the job needs, and the only way to find the right rotary is to call and ask.
The 2W IR Module: A Metal-Marking Option, Not a Miracle
Here's where I have to put on my procurement hat. The xTool S1 2W IR laser module is not a replacement for a full industrial fiber laser. It's an add-on that lets the S1 mark anodized aluminum, stainless steel, and some plastics. For us, it did exactly what the spec said. If someone tells you a 2W IR module can cut thick metal, don't believe it. I've learned to read the fine print.
We looked at a CNC fiber laser cutter for the same metal-marking jobs. The machine had an impressive spec sheet, but the total cost went beyond the machine: chiller, fume extractor, alignment fixtures, operator training, and floor space. We're a small shop, not a fabrication plant. The S1 plus IR module took a fraction of that budget and handled our real volume—roughly one batch of stainless tags per month. It wasn't faster in raw speed, but it was faster to actually use.
The Workflow Lesson: 'Laser Engraving Rocks' Is Not About Rocks
The most unexpected lesson came when I watched our team test laser engraving rocks. Flat slate coasters worked fine. River stones were a different story—they moved, they weren't level, and the engraved lines came out uneven. The fix wasn't a stronger laser. It was an affordable rotary accessory. I call this the workflow lesson: the bottleneck isn't usually the laser; it's the setup around it.
The same goes for air assist. At first I saw it as an upsell. Then I saw the difference in cuts on acrylic and plywood. Without air assist, we got more charring and wasted a couple of sheets. With it, the cuts were cleaner and the reject rate dropped. That's not an upsell. That's a quality problem. And with any laser, ventilation isn't optional—especially for plastics and coated metals.
We didn't have a formal equipment request process before this. The first laser we bought as a company was a no-name unit with a seller who couldn't provide a proper invoice. Accounting rejected $2,400 of the expense. That's the kind of hidden cost nobody mentions in the comparison table.
Check the Fine Print—and the Date
As of January 21, 2025, the xTool official product page lists the S1's modules and accessories separately, with current pricing. I recommend checking there before you order because specs and prices change. I can't speak to every local reseller or marketplace deal; I can speak to my experience with the official configurator and support team.
Is this a perfect machine? No. It can't do everything a CO2 or fiber machine can. But it also doesn't pretend to, and that's exactly the point.
Counterpoint: When the S1 Is Not the Answer
To be fair, if your work is cutting 6mm steel plate all day, you should probably buy a fiber laser, not a desktop diode engraver. If you need high-speed production on a single material, a dedicated machine may beat a modular one. I get why someone would look at a CNC fiber laser cutter and decide that's the right investment. Context matters. Granted, a high-volume metal shop should ignore most of what I've said.
But for a small shop with mixed materials and small batches, the S1 makes sense. The total cost is visible, the ecosystem is modular, and you can add capability over time. The 'headline vs. total' gap is smaller than anything else I priced.
Why I'd Buy It Again
In my opinion, the xTool S1 is the right choice for that situation because it's transparent. The xTool S1 engraver with the 2W IR laser module, rotary, and air assist isn't the cheapest config. It's the one that arrived with no surprises.
This worked for us. We're a small product-development shop with varied material requests and a budget-conscious finance team. If you're a high-volume metal shop, the math changes. But if you're tired of hidden fees and vague 'contact us for inside pricing', you'll appreciate a supplier that shows you everything upfront.
Look, I don't get paid to say this. I'm just an admin buyer who's been burned by vague quotes and 'you won't need that' accessories. Give me a clear line-item and a machine that does what the spec says, and I'll keep coming back.
