Laser cutters have improved over the years, and their transformation in size is noteworthy. What were once large, industrial-only machines are now accessible as desktop laser cutters to crafters and small businesses. However, the industry still faces a dilemma. Open diode lasers are budget-friendly but come with safety concerns, especially those with more laser power. Their enclosed counterparts are safer but come at a hefty price tag and less flexibility.
That’s where xTool S1, our groundbreaking 40W Enclosed Diode Laser Cutter, steps in! It brings unparalleled safety and unbeatable capacity to the table, all without breaking the bank. It is aimed at DIYers, designers, artisans, woodworkers, small businesses, and educators looking for affordable and high-powered lasers.

Stay with us as we reveal the standout features of xTool S1 and explore how it’s going to reshape the landscape of laser cutting!

Certified Class 1 Laser Product
The “S” in xTool S1 stands for safety – the xTool S1 is designed to be the safest diode laser in the market. It proudly meets the IEC Class 1 laser safety standards and holds EU CE certification. For those unaware of laser safety classification standards, Class 1 safety means the machine is safe to use under all normal conditions.

xTool S1’s enclosed structure speaks volumes of its safety. It has an advanced dual laser light filtering cover, integrating both blue and red lights. This innovative design makes those safety glasses unnecessary.
Furthermore, the device has a 100 CFM exhaust fan to maintain optimal air quality during use. The 5-direction flame detection sensors further add a safety layer and ensure a quick response to anomalies.
If you accidentally open the machine while it’s processing, the machine turns off automatically, thanks to the “Lid-Open Safety Stop” feature. And for any internal issues, there’s an emergency stop button at your disposal.
Incredibly Powerful 40W Diode Laser
The xTool S1 boasts a 40W high power, thanks to advanced laser compression technology. It merges eight 6W lasers to deliver cutting efficiency that stands toe-to-toe with CO2 machines. With such power, it can slice through 18mm of wood in one go!

Curious about what it can cut and engrave? Well, it can cut paper, wood, MDF, leather, felt, and opaque acrylic. And when it comes to engraving, the list is pretty extensive—stainless steel, dark glass, wood, leather, fabric, jade, ceramic, shale, marble, cement, brick, and painted metal.
The S1 also boasts an upgraded guide rail structure for increased stability. This allows the high-power laser to reach its full potential and ramp up efficiency. It holds steady, even at a high-speed movement of 600 mm/s.
And let’s not forget its versatility. It has switchable laser modules, including 40W, 20W, 10W diode laser modules, and a 2W infrared laser module. The infrared module is especially cool for finely engraving metals and plastics.
Smarter and Easier than Ever
Tool S1 elevates user-friendliness with its innovative features. First up, Twin-point Positioning. It’s as straightforward as it sounds. The precise camera-like sensor system measures two points’ coordinates to define the processing range. The information is displayed in real-time on the software, and patterns get imprinted within exact limits. It’s a leap beyond the precision of traditional methods.
Our test users were all in praise of this new feature as they printed out patterns on a 75 mm round glass piece, and the engravings were perfectly centered.

The second standout feature is the Autofocus Engraving, which makes S1 as precise as a computer. It helps by moving the spot below the cutting surface, enhancing cutting power.
Lastly, S1 has a Dynamic-focus Engraving System for dynamic and curved engraving. It allows high-precision ranging and 3D object modeling. The motorized Z-axis adjusts focus during processing. This makes every engraving perfect, even on uneven surfaces.

Creation Amplified Beyond Limits
Then there’s the RA2 Pro rotary attachment, which allows for working on round items like tumblers, mugs, spheres, and rings.

Lastly, let’s not overlook the Smart Air Assist. It automatically tweaks the airflow size based on the processing status, ensuring every creation turns out just perfect.
