If you’re looking to dive into laser cutting and engraving—whether for hobby, side-business, or full DIY workshop expansion—the xTool S1 40W is one of the more compelling all-in-one machines worth your attention. Below is a detailed blog-style review of what it offers, how it stacks up, and whether it might be a fit for you.
What is the xTool S1 40W?
The xTool S1 line is a desktop-sized, enclosed diode laser cutter & engraver, and the “40W” variant refers to its higher-power diode laser head (versus 20W/10W versions). According to the manufacturer, the 40W model uses “advanced laser compression technology” (eight ~5.5W lasers combined) to achieve cutting efficiency comparable to some CO₂ machines.

Laser power: 40 W diode module. xTool Laser Cutter+1
Working area: about 498 × 319 mm (≈ 19.6″ × 12.5″) for the S1. xTool Laser Cutter+1
Speed: Up to ~600 mm/s movement speed cited. Swing Design+1
Additional modules: The machine supports optional modules (e.g., 1064nm IR laser for metal) on the same platform. xTool Laser Cutter+1
Enclosed build and safety: The machine is sold as an “enclosed diode laser cutter” with various safety features. xTool Laser Cutter
So essentially: This is a premium-desktop level diode laser encapsulated in an enclosure (for fume/safety control) aimed at makers, small business users, and workshop-creators who want both cutting and engraving in one unit.
Key Features & What Stands Out
1. Power + Cutting Capability
One of the strongest selling points is the 40W diode output. On a desktop enclosure machine, that is relatively high, and manufacturers claim it can cut through ~18 mm cherry wood in one pass. Swing Design That opens up possibilities for thicker materials, more substantial signage, layered artwork, etc.
2. Enclosed Design & Safety
Because it’s enclosed, the machine offers better containment of fumes, particles, and stray reflections compared to open-frame lasers. The website mentions “Class 1 safety” levels (for the 40 W version) and amenities like a flame sensor, emergency stop, and lid safety. Amazon For home or small-business use, the enclosure is a big plus in terms of allowing more flexibility of location (though still ensure proper ventilation, safety protocols).
3. Versatility & Modules
The S1 supports additional modules—so you’re not locked into one laser type forever. For example, you can plug in a 1064 nm IR head for metal engraving. xTool Laser Cutter This means the machine can evolve from wood/acrylic to more advanced materials. It also supports accessories like honeycomb cutting bed, air-assist, rotary attachments, etc (depending on bundle). Swing Design
4. Software & Workflow
xTool offers the “xTool Studio” (or “Creative Space”) software, designed to be user-friendly. There’s also “Pin-point Positioning™” tech for accurate alignment. According to xTool’s website: “One-pass engraving success, zero waste” and claims of being “10 × more accurate than single-camera systems”. xTool Laser Cutter Also, with the enclosed, pre-tested materials and presets (over 400 materials claimed) they aim to reduce the “trial & error” barrier for beginners.

5. Workspace & Throughput
The nearly 20″ × 12.5″ bed gives you real working area (not just tiny tags). At speeds up to 600 mm/s, you can reasonably imagine doing moderate production runs (e.g., multiple signs, tags, tumblers, etc). According to the Amazon listing: “up to 119 dog tags in one go” for example. Amazon For many small business or maker-shop users, that’s big.
Strengths & Opportunities — My Take
✅ What I like
Great balance of power, size, and safety: A 40W diode in an enclosed format is compelling for a higher-end hobbyist/small-business level.
Flexibility of materials: With the right module and accessories you can go from wood, acrylic, leather, fabric to more advanced materials (depending on module).
Upgrade path: The optional modules and accessories enable future-proofing (rotary, passthrough, metal engraving).
User-friendly workflow: For those less experienced, the pre-testing, the software, and the brand’s push make entry easier.
Production potential: Enough bed size + speed to do actual business work (not just one-offs).
⚠️ What to consider / possible drawbacks
Ventilation & safety still matter: Even though it’s enclosed and safer than open lasers, you’ll still need proper ventilation, fume extraction, and safe usage protocols. The enclosure doesn’t eliminate all need for safe setup.
Material limitations of diode lasers: While diode lasers are powerful in this machine, they may still lag behind larger CO₂ or fiber lasers on certain materials (especially things like clear acrylic, some metals, thick metals). The IR module can expand metal capability, but cost will go up.
Cost and footprint: This is not the cheapest hobby laser. Also, the size (bed + enclosure + accessories) means you need dedicated space.
Learning curve: While the software aims to simplify things, real mastery (for clean cuts, deep engraving, production workflows) still takes experience—especially when working with varying material properties, thicknesses, and finishes.
Consumables and maintenance: Air assist, focus maintenance, bed cleanup, proper material prepping—all these matter for consistent results. Some users (on forums) point out that even with high-end machines you’ll still need to dial in parameters.
“I found cutting speeds seem to increase linearly with laser power. So going from 20w to 40w does seem to be about twice the cutting speeds on wood and acrylic.” RedditThat’s promising—but it also underlines that material + parameter tuning still matter.
Ideal Use-Cases & Who It’s For
🎯 Hobbyist / Maker
If you’re a maker or hobbyist who wants to jump into more serious work — bigger artwork, thicker materials, perhaps some side-sales (custom signs, tumblers, leather goods) — the S1 40W is a strong choice. The enclosure and safety features help for home use.
🛠 Small Business / Customization Shop
If you run a small custom-goods business (e.g., tumblers, signage, corporate gifts, trophies, leather accessories) this could be a centerpiece machine. The bed size and speed allow multiple pieces in one go. The upgrade path (like rotary for tumblers) is a real plus.
🎓 Education / Makerspace
For a makerspace, classroom, or workshop environment where users will vary, the enclosed design and safety features are helpful. It gives a more robust “industrial” feel while still being accessible.
❌ Less Ideal For
Pure large-scale industrial production (where you’d likely want a large CO₂ or fiber laser).
Materials that require very high-power / specialized lasers (thick steel, clear glass, etc) unless you get the appropriate module and budget accordingly.
Very tight budgets or minimal spaces where size/venting are major constraints.
Tips & Best Practices for Getting the Most Out of It
Set up proper ventilation: Even enclosed machines generate fumes/smoke when cutting wood, acrylic, leather. Use an exhaust fan or fume-extractor.
Use air assist: This helps keep cuts clean (especially thicker materials) and prevents heat damage or charring.
Test materials and keep a parameter log: Because materials vary a lot in thickness, coatings, grain, color etc., it pays to log your best settings for each material.
Maintain focus and alignment: Enclosed machines reduce stray reflections but you still need clean optics, proper alignment, and bed leveling.
Take advantage of the software’s presets, but don’t rely on them entirely: Start with manufacturer presets, but do fine-tuning—especially for your specific materials.
Consider accessories early: If you will do tumblers (rotary), long-signs (passthrough), or curved surfaces (3D engrave), budget for the accessories and plan space accordingly.
Think about safety beyond the machine: Laser safety includes fire risks (cutting wood/acrylic can ignite), ventilation, eyewear (even if Class 1), and ensuring that your workspace meets electrical and clearance needs.
Final Thoughts
The xTool S1 40W is a well-rounded, feature-rich machine that genuinely bridges the gap between high-end hobby and small business level laser fabrication. With a good size bed, serious diode power, enclosed safety features, and upgrade flexibility, it’s a strong contender for anyone looking to go beyond “just tinkering” into meaningful creation or commerce.
If I had to sum it up: If you are ready to commit space, budget, and workflow, the S1 40W gives you serious capability; if you’re just curious and budget-limited, you might explore lower-power options first. But for many users, it’s a “buy it once and grow into” tool.
If you like, I can compare the S1 40W with a few other machines (e.g., its 20W sibling, a similar CO₂ machine, etc.) so you can see how it stacks up in price/performance. Would you like me to pull that together?
