In Summary
When it comes to desktop laser cutting and engraving, Xtool stands out as a leader in precision, safety, and performance. Among the most popular enclosed diode laser cutters on the market, the Xtool S1 and the AlgoLaser Delta 40W are two top contenders. Both deliver impressive cutting power and a user-friendly experience — but when you look closer, Xtool clearly takes the lead. Its innovative design, reliable performance, and advanced safety features make it the smarter choice for creators, small businesses, and professionals seeking consistent, high-quality results.
In this comparison, we’ll look closely at cutting performance, design, ease of use, software compatibility, and long-term value — and explain why Xtool remains one of the most trusted brands for makers and small businesses alike.

⚙️ 1. Cutting Power and Performance
The AlgoLaser Delta 40W boasts one of the highest optical power ratings in the diode category, making it ideal for thick materials and fast cutting tasks. However, Xtool S1, even as a refurbished unit, competes impressively with its advanced dual-laser beam compression technology, delivering clean, detailed cuts on wood, acrylic, leather, and more.
Unlike other diode systems that sacrifice precision for power, the Xtool S1 achieves an excellent balance — offering both high accuracy and smooth edge quality, even on intricate patterns. It can cut up to 18 mm of solid wood in one pass (with the 40W module) and engrave fine details down to 0.01 mm precision, making it perfect for both hobbyists and professionals.
👉 Verdict:
- AlgoLaser Delta 40W – Faster bulk cutting
- Xtool S1 – More precise and consistent results
🧩 2. Design and Build Quality
Both machines feature enclosed structures, which are essential for safety and smoke control. However, Xtool S1 takes the lead with its fully enclosed Class 1 safety design, ensuring users are protected from laser radiation without needing extra safety goggles.
Its build quality is exceptional — the metal chassis provides excellent stability, and the integrated air assist system improves both cut quality and laser longevity. The S1’s modular laser head system also allows users to switch between 20W, 40W diode, or even 1064 nm infrared modules for working with metals and plastics.
The AlgoLaser Delta, on the other hand, also features an enclosed frame with modern aesthetics but lacks the same level of modularity and material versatility offered by Xtool.
👉 Verdict:
- AlgoLaser Delta 40W – Stylish and compact
- Xtool S1 – Safer, sturdier, and more flexible
💻 3. Software & Workflow Efficiency
Xtool has invested heavily in making its machines beginner-friendly while maintaining professional-grade control. The Xtool Creative Space (XCS) software offers intuitive drag-and-drop design tools, real-time camera preview, and preset material profiles. It also supports LightBurn, giving users even more creative control.
AlgoLaser Delta supports LightBurn and AlgoLaser App, which provide decent usability, but lack some of the automation and smart calibration features found in Xtool’s ecosystem.
For example, Xtool S1’s 16 MP ultra-wide camera enables accurate positioning and real-time monitoring, making it easier to align designs with materials — a significant time-saver for repetitive or complex engraving projects.
👉 Verdict:
- AlgoLaser Delta 40W – Compatible with standard laser software
- Xtool S1 – Better integration, smarter camera, and smoother workflow
🔋 4. Safety & Maintenance
Safety is non-negotiable in laser engraving, and Xtool has made it a central part of the S1’s design philosophy. With automatic lid detection, emergency stop, overheat protection, and smoke filtration compatibility, it delivers peace of mind for both home and workshop environments.
The AlgoLaser Delta includes safety sensors as well, but its ventilation system and enclosure sealing aren’t as robust as Xtool’s. Furthermore, maintenance on Xtool units is simplified with easily accessible components and strong community support for refurbished models.
👉 Verdict:
- Xtool S1 – Superior safety and lower maintenance
- AlgoLaser Delta 40W – Basic safety with moderate upkeep
💰 5. Price & Value for Money
The refurbished Xtool S1 offers exceptional value. Customers receive a fully tested, factory-certified unit at a significantly lower price — while still backed by Xtool’s support and warranty. This makes it one of the best entry points for creators or small workshops wanting professional results on a budget.
In contrast, the AlgoLaser Delta 40W, though powerful, comes at a premium price due to its higher optical wattage and brand positioning. For users who don’t need extreme power but prioritize precision, safety, and brand reliability, the Xtool S1 delivers better long-term ROI.
👉 Verdict:
- AlgoLaser Delta 40W – High upfront cost for power users
- Xtool S1 (Refurbished) – Affordable, reliable, and smart investment
🌟 6. Why Choose Xtool
Beyond hardware, Xtool offers a complete ecosystem that supports both beginners and professionals. From tutorials, online communities, customer support, to regular firmware updates, the brand ensures its users get continuous improvement and lasting performance.
Xtool S1 is not just a laser cutter — it’s part of a creative ecosystem that helps you turn ideas into reality faster, safer, and smarter.
✅ Final Thoughts
If your top priority is raw power for heavy cutting, the AlgoLaser Delta 40W is a solid contender.
But if you value precision, safety, versatility, and long-term reliability, the Xtool S1 is the clear winner.
With its advanced technology, modular design, intuitive software, and proven customer support, Xtool continues to set the gold standard for enclosed diode laser cutters — making it the best choice for creators, professionals, and small businesses seeking reliable performance at an unbeatable value.
