In 2021, I took over purchasing for a 40-person manufacturing company. Since then, I've reviewed more equipment quotes than I can count, and I've learned one thing: the most expensive option is rarely the right option, and the cheapest one is almost never the right one either.
The xTool S1 diode laser is a perfect example. It's one of the most popular laser cutters in its class, and you'll see plenty of reviews saying "get the highest wattage you can afford." I think that's lazy advice. The S1 comes in three versions—10W, 20W, and 40W—and the right configuration has more to do with your business model than with the wattage itself.
In the past year, I've worked with three types of buyers: small-shop owners doing custom engraving, production teams using the S1 for industrial laser engraving, and hobbyists who want a versatile makerspace tool. They need different setups, and I've organized this guide around those three scenarios.
Scenario 1: Small Custom Shop
You're making custom gifts, signage, trophy plaques, leather goods, or wedding favors. You might have an Etsy store alongside local orders. Volume is moderate—a few dozen pieces per week, not per day.
I'd put you in the 20W S1. The 20W handles the full material range that custom shops rely on: it cuts 8-10mm wood and acrylic in a single pass, engraves anodized aluminum cleanly, and processes leather and glass without issue. It also does color engraving on metal—either with xTool's color-coated sheets or via heat oxidation on stainless steel. That might sound niche, but custom drinkware with colored logos is a legit revenue stream, and having this capability makes you more than just a "wood engraver."
Pair it with:
- Air assist (~$99-149) — noticeably cleaner cuts and less charring. I'd call it mandatory.
- Rotary attachment (~$169-199) — required for cups, bottles, and spherical objects. Budget for it from day one if you plan to serve the drinkware market.
- Honeycomb panel (~$79-119) — prevents scorch marks on the underside of your material.
As of January 2025, an S1 20W with these accessories lands around $1,200-1,500 depending on where you buy. Promotions change fast, so verify current pricing before you set a budget. My strong advice is to skip the 10W if you're generating actual revenue—it's a fine machine, but it's slower, and speed shows up directly in your margin when you're running a business.
Scenario 2: Production Floor and Prototyping
You're using the laser for parts marking, serial numbers, tool engraving, or prototype runs. Volume can be high, but precision and repeatability matter more than raw speed. This is the classic industrial laser engraving use case, and it's where the conversation usually gets complicated. To be fair, if your operation is heavy on thick acrylic cutting or production-scale plywood work, a CO₂ laser is a different category entirely and you should be looking there. The S1 doesn't replace that. But for surface marking and thin sheet metal engraving, it deserves a seat at the table.
I'm going to push back on a common assumption: that production environments automatically need a fiber laser or CO₂. That's not always true. The 40W S1 can handle sheet metal engraving tasks that historically would have been done on machines costing three times as much. For example:
- Engraving stainless steel nameplates and inventory tags
- Marking tools with ID numbers for asset tracking
- Etching metal panels for control boxes
- Color engraving on stainless steel—the oxidation marking on the 40W produces a durable rainbow effect that looks like it came off a much more expensive setup
That said, I don't automatically recommend the 40W. Here's the counterintuitive part: if your daily output is under 50 pieces and you're mostly batch-marking metal tags a few days per week, the 20W will get you there with slightly longer cycle times. The 40W pays for itself when you're running it daily, or when you need extra speed on anodized aluminum. For one-off prototypes, the $500 price difference is better spent on a rotary and a proper extraction setup.
On safety: the S1's enclosed design is a real workplace plus compared to open-frame diode lasers. But enclosed is not the same as ventilated. Cutting and engraving produce fumes, especially from plastics and coated metals, and you still need exhaust or a serious filter. A production manager I know ran one in a small room with no airflow—the optics hazed over in two weeks, and cut quality dropped fast. Add ventilation to your budget, period.
Also set honest operational expectations: treat the S1 as a batch-work machine, not a 24/7 line. Plan for roughly 35-45 minutes of setup per job at first, including material prep and software positioning. It'll run for several hours of production work, but it wants a cool-down between bigger runs. That's true of every laser at this price point, and being upfront about it—instead of discovering it after a missed deadline—will save you a painful conversation with your team.
Scenario 3: Maker, Hobbyist, or First-Time Owner
You want a laser for personal projects, small gifts, maybe a side business later. Budget matters, and you can live with slower speeds.
Honestly? The 10W is enough. I get pushback on this because the internet says "you'll upgrade later." Maybe you will. But there are plenty of owners who buy the 20W and never use half of its capacity. (Note to self: stop over-specing things.)
That said, if the gap between the 10W and 20W is one busy weekend of freelance work, stretch for the 20W. The speed difference on 6mm wood is roughly double, and having the headroom to engrave coated metals without buying additional modules is a genuine upgrade. It's the "buy once, cry once" argument, and I think it's valid here.
My rule of thumb: if you already know what you'll make in your first 30 days, buy for that. If you don't, buy the 20W and don't look back.
Hidden Costs and Transparency
Since I live in vendor invoices every day, I've learned to ask "what's NOT included" before asking "what's the price." This is where the S1 actually impressed me—not because it's cheap, but because the pricing structure is unusually straightforward.
The base S1 includes the unit, the safety shield, and the control software. LightBurn, the third-party software most owners use, is a one-time ~$60 license. There's no subscription wall to access basic features. That's rare in this market, and worth saying out loud.
The accessories (rotary, honeycomb, air assist, riser base) are sold separately, but they're clearly listed on xTool's site—no surprises at checkout. The cost people routinely under-budget is ventilation: a simple outside-venting hose kit or a small air filter starts around $100-300. Don't skip it.
Price reference (public listings, January 2025):
xTool S1 10W: ~$599-699 · xTool S1 20W: ~$899-999 · xTool S1 40W: ~$1,399-1,499
Rotary attachment: ~$169-199 · Air assist: ~$99-149 · Honeycomb panel: ~$79-119
Laser module upgrade (20W → 40W): ~$500-600
Prices change quickly—verify current rates before budgeting.
For context, many brands in this category list a low base price and then charge separately for things that should arguably be standard. The S1's accessory ecosystem is comprehensive, yes, but at least you can see the full cost before you hit "buy." Transparent pricing is the foundation of any good vendor relationship, and when the total makes sense, I don't mind the line items.
Which Scenario Are You In?
Still not sure? Ask yourself three questions.
1. How many pieces per week? Under 20 is hobbyist territory. 20-100 is small-shop territory. 100+ is production territory. These are rough ranges—adjust for what you're making.
2. What's your most common material? If it's wood, acrylic, leather, or glass, any version works; the decision is driven by volume, not material. If it's stainless steel or anodized aluminum, think 20W as a minimum and 40W if that's a daily job.
3. What's your budget beyond the machine? Accessories, ventilation, and test materials add up. When I built a complete small-shop estimate in 2024, the laser itself was only about 60% of the total. It's a system, not just a device.
If you're still on the fence after those questions, go with the 20W. It's the boring answer, but in the best sense: it's the configuration that covers the widest range of jobs at a price that doesn't make you second-guess the decision later. That's the definition of a safe procurement call. No laser cutter in this price class is the "best" for everyone, but the xTool S1 is one of the best laser cutters for a business that wants multi-material flexibility at a transparent price.
I went back and forth between the 20W and 40W for our own shop for two weeks before realizing I was asking the wrong question. It wasn't "which is more powerful?" It was "which configuration makes our orders profitable?" When you answer that for your situation, the choice gets a lot easier.
One last note: the pricing above was accurate as of January 2025, and the laser market moves fast. Verify current rates before budgeting. And if you can, talk to another owner using the same config you're considering—that conversation is worth more than any spec sheet (I've learned this the hard way).
