Ranked #4 in Best Laser Engravers
xTool F2 Ultra UV
6 sources$7,311.58as of Oct 1

The xTool F2 Ultra UV utilizes 355nm cold-processing technology to engrave heat-sensitive materials like chocolate and paper without charring or melting, while its interchangeable lens system enables embedded 3D crystal work. Hobbylasercutters highlighted this unique inner engraving capability as a standout feature for the machine. However, the device operates exclusively within the closed xTool Studio ecosystem, which lacks compatibility with third-party tools like LightBurn, and its material preset library is incomplete, requiring manual tuning for many substrates. Hackster.io noted that this software restriction may be a dealbreaker for some users. This laser suits makers who prioritize thermal-free precision on delicate items over open-source workflow flexibility.

Strengths
  • — Cold-processing UV technology at 355nm enables photochemical ablation that engraves without burning, charring, or melting heat-sensitive materials like chocolate and paper.
  • — Capable of embedded 3D inner crystal glass engraving using a specialized interchangeable lens and precision pedestal stand included in the package.
  • — Features dual 48-megapixel internal cameras that provide accurate positioning down to approximately 0.2 mm and support auto-focus workflows.
Watch-outs
  • — The xTool Studio software ecosystem is closed, offering no compatibility with third-party tools like LightBurn which many makers prefer.
  • — The material preset library in the software is incomplete, requiring users to manually dial in settings for many specific materials not listed by default.

Xtool S1 40W
8 sources1 derived$1,499as of Oct 1

The Xtool S1 40W offers a fully enclosed Class 1 design that ensures safety by containing fumes and preventing laser leakage, while magazine.raspberrypi found this complete enclosure removes the need for protective eyewear during operation. Its interchangeable modules allow users to switch between blue diode cutting and infrared metal engraving, though hobbylasercutters noted that precise physical alignment is critical because the system lacks a visual preview camera. The machine’s primary drawback is its inability to cut clear acrylic or transparent plastics due to the limitations of its blue wavelength laser technology. This model fits makers who prioritize safety and modular versatility for wood and dark materials, but those requiring work with glass or clear sheets should look elsewhere.

Strengths
  • — Fully enclosed Class 1 design provides comprehensive safety against laser leakage, fumes, and fire with automatic shutoff.
  • — Interchangeable laser modules allow switching between 40W blue diode for cutting and 2W infrared for metal engraving without buying new machines.
  • — Pin-point positioning system uses a physical probe to locate workpieces accurately, avoiding the distortion issues common in camera-based systems.
Watch-outs
  • — Cannot cut clear acrylic or transparent plastics due to the blue wavelength limitations of diode lasers.
  • — The included exhaust hose has a small diameter (3.25 inches) and short length, often requiring third-party extensions for garage use.
  • — Lacks an integrated camera for visual previewing, relying instead on physical markers which can miss material if not carefully aligned.

How they stack up

xTool F2 Ultra UV

The xTool F2 Ultra UV uses cold-processing UV technology to engrave heat-sensitive materials like chocolate without charring, a capability the standard diode lasers in the Glowforge Aura or Creality Falcon A1 Pro lack. Although it offers precise 0.2mm positioning via dual cameras, its closed software ecosystem restricts third-party tool compatibility unlike the open workflows preferred by many makers.

Xtool S1 40W

The Xtool S1 40W offers interchangeable modules for switching between blue diode and infrared metal engraving, providing versatility similar to the Creality Falcon A1 Pro but with a different motion system. Unlike the xTool F2 Ultra UV which uses cameras for positioning, the S1 relies on a physical probe for pinpoint accuracy, avoiding distortion issues common in camera-based systems.
