Earlier this month, a contact who runs a six-person sign shop asked me a question I’ve now heard four times since Q4 2024: “Should I buy the xTool S1 40W, or is the 20W really enough?”
I’m not a laser engineer, and I don’t run engraving jobs at our shop. I’m the person who approves purchase orders. That role leaves a paper trail: six years of equipment and material spending at a 14-person custom goods company, roughly $150,000 a year, tracked line by line. If your search history already contains “xtool s1 40w laser cutter,” this is the angle most reviews skip.
Short version: the xtool s1 40 watt is a genuinely good machine, but it’s the right purchase in only one of the three scenarios below. Work out your scenario first, then shop.
Three Questions That Decide Your Scenario
I used to answer “which laser is best” with spec comparisons. That was lazy. After roughly 40 equipment decisions and a few expensive do-overs, I stopped asking which machine is best and started asking what situation the buyer is in. The same machine can be smart capital spending for one shop and a mistake for the shop next door.
Three filters go on every equipment request now:
- How many paid jobs are on your calendar for the next 30 days?
- What materials are actually in those jobs?
- What is an hour of your time — or your operator’s time — worth, fully loaded?
No “future-proofing.” No “I’ll get into it later.” Those aren’t cost inputs, they’re hopes. Hopes are fine, but they don’t belong in the budget.
Scenario A: No Real Orders Yet → Buy the 20W, Not the 40W
This is where most first-time buyers sit. There’s a product idea, maybe an Etsy page, a laser engraver you once used at a maker space. No steady orders. If that’s you, the extra money for the 40W isn’t an investment yet. It’s an expensive hobby.
The 40W’s advantage shows up in two places: thicker cuts and repeated production. It doesn’t show up when the machine sits idle for most of the week, which is what happens in the first months with no product line. Idle capacity doesn’t just sit there. It depreciates.
Most first-time buyers compare wattage and completely miss the second invoice: rotary attachment for tumblers, honeycomb cutting surface, a fume hose or filter, and all the test material you will burn through while learning the settings. (Should mention: the S1’s enclosure and air assist are included, which is one reason we looked at it instead of an open-frame diode.) The 20W still gives you those basics, and it leaves budget for everything else.
If you buy the 20W now, set an honest upgrade trigger: don’t move to the 40W until you’ve logged 10+ paid laser hours a week for four consecutive weeks. That’s measurable. “Someday” isn’t.
Take it from someone who has watched small businesses buy machines eight months before revenue justified them: the machine will still be available when the orders show up. The wasted months of depreciation won’t come back.
Scenario B: You Have a Production Queue → the 40W Is Often the Cheaper Buy
Now flip the usual advice. If you already have clients, repeat orders, and a weekly “next batch” conversation, the 40W can be lower total cost than the 20W even though it costs more up front. That sounds backwards until you account for labor.
In Q4 2024, we were quoting a recurring job of engraved wooden tags, 3 mm birch plywood. Our 20W machine needed two passes to cut that material cleanly. The 40W did the same cut in one pass at a faster speed, and the edge was cleaner. Batch time dropped by roughly a third. On a repeating order, that’s hours every month, not minutes. Hours are labor, and labor is the line item most retail price comparisons ignore.
I want to say our invoice for the 40W bundle came to around $1,900 in October 2024, but don’t quote me on that — xTool runs sales constantly, and I don’t track retail prices, I track what we actually paid. Verify current pricing on their official store before you budget. The point isn’t the exact number. The point is the gap between 20W and 40W gets repaid surprisingly fast when the machine runs every day.
The hidden cost is redoes. In our production log, an underpowered cut meant melted edges and re-cutting pieces. Redoing a client’s order costs twice: material, then labor, then the delay. The cheaper machine’s sticker price doesn’t appear on that line. Its scrap rate does.
If you’re in Scenario B, the 40W isn’t an indulgence. It’s capacity, and capacity is what you’re actually selling. Buy the wattage that matches the backlog, not the wattage that feels comfortable.
Scenario C: You Might Be Comparing the Wrong Category of Machine
This is the quiet one. Some of you found this article after searching “cnc laser cutter price” or “pico laser machine,” and those phrases can lead you into a category mistake. Not a brand mistake — a category mistake. Let me untangle both.
Part of the confusion is that the industry is evolving faster than its vocabulary. Ten years ago, “laser cutter” meant one of two things: a hobby diode or an industrial CO₂/fiber system. In 2025, an enclosed 40W desktop diode blurs that old line. The fundamentals haven’t changed — wavelength and material absorption still decide what cuts — but the price points and capabilities have shifted so much that old assumptions no longer hold.
“Pico laser machine.” If you’re shopping for that phrase, you may be looking for a picosecond laser: an industrial system used for fine marking on metals, ceramics, and semiconductors. That equipment category usually runs from tens of thousands of dollars into six figures. A desktop diode laser is not a budget alternative to it. The S1 can mark coated or anodized metal, but it will not give you deep engraving on bare steel or micro-scale industrial marking. Wrong tool, wrong budget class.
“CNC laser cutter price.” Careful here too. A CNC router cuts with a spinning bit; a laser cuts with light. People use the phrase “CNC laser” for both, then discover the machine they bought can’t do what the other technology does. If your real project involves cutting aluminum or thick steel, no desktop diode laser — not even a 40W one — is the answer. You’d be looking at fiber or high-power CO₂ equipment, and the budget conversation changes completely.
If this sounds like you, my procurement answer is boring: freeze the purchase until you can write down the material, thickness, finish, and expected volume, then ask suppliers which category handles it — desktop diode, CO₂, fiber, picosecond, or CNC router. A $2,000 mistake is annoying. A $30,000 mistake is a bad quarter.
Okay, But How Do You Cut an Acrylic Sheet?
We get “how do you cut an acrylic sheet” so often it deserves its own section, because material choice can kill an otherwise good purchase plan.
Yes, you can cut acrylic with the S1 40W — under the right conditions. But “acrylic” is not one material from a laser’s point of view. Clear transparent PMMA transmits blue 455 nm light instead of absorbing it, which is why clear acrylic is the classic job for a CO₂ laser, not a blue diode. No amount of wattage fixes that. If your business plan depends on cutting clear acrylic sheets all day, the machine category you actually need is probably CO₂, and you should budget for that instead.
Opaque or dark-colored acrylic is a different story. That’s where the S1 40W can work. From our operator’s notes, which I’m summarizing rather than translating into engineering language:
- Confirm the sheet is actually acrylic (PMMA). Unmarked polycarbonate, PVC, or ABS can release toxic fumes when lasered. If you don’t know what the sheet is, don’t cut it.
- Keep test pieces small. Cut a small grid of settings first, write down the winners, and only then run the real sheet.
- Use air assist and expect multiple passes at lower speeds. One heavy pass usually makes a worse edge than two lighter ones.
- Budget for fume management. Even with air assist, acrylic smoke is something you don’t want in your lungs or your shop.
This gets into material-science territory where I’m not the expert. What I can tell you from a procurement view is simple: test material is cheaper than finished scrap, and the scrap pile teaches faster than any spec sheet.
Which Scenario Is Yours? A 10-Minute Check
Still unsure? Do the exercise, not the guess.
If you have zero paid jobs in the next 30 days, treat yourself as Scenario A. Buy the 20W, set the upgrade trigger I mentioned, and spend the difference on material and accessories.
If you have repeat orders and a backlog that involves wood, leather, opaque acrylic, or coated metal, treat yourself as Scenario B. Run the time comparison on your own files, then decide. I’d be surprised if the 40W doesn’t win on cost per finished part.
If you still can’t name the material, or you arrived here from “pico laser machine” or “CNC laser cutter price” searches, treat yourself as Scenario C. No purchase until the category question is answered.
Final thought from six years of approving orders: the expensive mistakes aren’t paying too much for a machine that runs. They’re paying for capacity that sits idle, or paying wages while a machine can’t keep up with the work. Decide which risk you’re actually taking. That decides your wattage.
