xTool S1 Review — Everything You Need to Know

“If your budget allows, you can’t go wrong with the xTool.”

The xTool S1 is an enclosed diode laser engraver designed to combine strong performance with enhanced safety and automation.

It targets beginners in the laser engraving world seeking a secure alternative to open-frame diode lasers without the maintenance requirements and cost of CO₂ systems.

The S1 aims to bridge that gap by offering both professional-grade results and user-friendly operation.

Design and Unboxing Experience

The machine arrives well-packaged, reflecting xTool’s focus on safe delivery.

Assembly is minimal — typically limited to connecting the laser module, air-assist hose, and exhaust duct.

Setup takes less than 20 minutes. The enclosure feels rigid and precisely assembled, with a matte finish and smooth mechanical movement of the lid and rails.

Key Specifications and Features (Verified)

Performance and Material Testing

Extensive testing confirms that the S1 achieves precise engraving and efficient cutting within its power class.

Wood

The S1 produces clean, contrasted engravings on plywood and hardwoods.

Using the 40 W module, it cuts ≈ 6 mm (¼ in) plywood in a single pass and up to 12 mm (½ in) in multiple passes under optimized settings and air assist.

Acrylic

Colored opaque acrylic cuts cleanly with the diode modules.

Transparent acrylic engraves successfully but cannot be cut efficiently due to wavelength limitations common to blue lasers.

Leather and Slate

On leather, the S1 achieves fine contrast with minimal scorching. Slate produces clear, permanent marks suitable for decoration or branding.

Metal Engraving with IR Module

The optional 2 W infrared module engraves stainless steel and aluminum directly with high precision.

This module operates at 1064 nm, ideal for metals and certain plastics, whereas the diode lasers engrave only coated surfaces.

Cutting Precision and Speed

Cuts are accurate and edges remain clean thanks to integrated air assist.

Speed tests show noticeably faster processing than earlier open-frame xTool models, making the S1 efficient for batch production.

Software and User Experience

xTool Creative Space (XCS) provides an intuitive environment for beginners — featuring drag-and-drop design, auto material measurement, and preset profiles for common substrates.

LightBurn support allows advanced users to access custom power/speed curves, layers, and advanced path control.

Setting up through USB or Wi-Fi is straightforward. Both programs deliver smooth workflows from import to execution.

Safety and Environmental Control

Safety is a core strength of the S1. The fully enclosed design eliminates direct laser exposure and contains fumes.

• An active flame detection sensor halts operation if combustion is detected.
• A lid interlock prevents laser emission when open, and the emergency stop button ensures immediate shutdown if needed.
• An internal fan and exhaust duct direct smoke outside; external ventilation is still recommended for indoor use.

Pros and Cons (Summarized)

Pros

• Completely enclosed for maximum operator safety
• Supports three laser modules (20 W, 40 W, 2 W IR) for versatility
• High precision and stable cutting with integrated air assist
• Auto-focus and auto-measure features reduce setup time
• Strong build quality and consistent engraving results
• Beginner-friendly software with professional options

Cons

• Higher cost than open-frame alternatives
• Fixed workspace smaller than expandable models like xTool D1 Pro
• IR module requires parameter experimentation for optimal metal engraving
• Fan noise moderate during operation (common to enclosed systems)

Target Users and Applications

The xTool S1 is best suited for:

• Beginners and hobbyists seeking a safe, plug-and-play engraver
• Small businesses requiring consistent quality for custom goods
• Home workshops with limited space that need a contained system
• Education and design studios prioritizing safety compliance

Its compact form factor and multi-module support make it a versatile choice for creative production and light manufacturing.

Competitive Comparison

Pricing and Value Assessment

The xTool S1’s price varies by configuration:

• 20 W kit: ≈ USD 1,499
• 40 W kit: ≈ USD 1,999
• 2W Infrared Module: ≈ USD 599

While more expensive than basic enclosed lasers, the S1’s added automation, safety, and precision justify the premium for users seeking a turn-key solution.

It can be purchased from xTool official store or authorized retailers like Amazon, with a standard warranty and after-sales support.

Final Verdict

For users who prioritize safety, ease of use, and professional-grade results in a desktop format, the xTool S1 offers exceptional value.

It’s particularly recommended for small businesses and serious hobbyists who need consistent performance with minimal setup hassle.

Meanwhile, if you’re looking for a more budget-friendly option, the Falcon A1 Pro serves as a lower-cost alternative to the S1.

It delivers comparable functionality and engraving quality—without the extra cost that often comes with a premium brand name.
