- Cold processing at 355 nm: Molecular-bond photochemistry leaves no heat-affected zone, keeping edges burn-free on wood, acrylic, and leather without post-cleaning.
- Dual 48 MP camera vision: Automatic focus and positioning remove the manual alignment steps that slow single-camera UV systems.
- Two switchable field lenses: A single enclosure serves both 3D inner-engraving inside glass and flat surface work.
- xTool Studio AI conversion: Flat photos become printable 3D models automatically, removing the need for prior CAD skills.
Technology & Operating Principle
Most desktop lasers operate in the infrared spectrum, cutting and engraving through generated heat. The F2 Ultra UV instead uses a 355 nm ultraviolet source: high-energy photons break molecular bonds directly, transferring almost no heat into the material. This photochemical action is called cold processing, and it is why the F2 Ultra UV produces burn-free edges without pre-coating or post-polishing.
Cold Processing at 355 nm
The UV spot measures 0.02 × 0.02 mm, over 100 times smaller than a typical CO₂ spot. Combined with the 0.001 mm vector-fitting resolution, this lets the machine engrave text as small as 0.3 mm and mark watch components at 0.2 mm positional accuracy.
The diagram below maps the 355 nm wavelength against its three core process advantages.
Burn-Free Results Across Heat-Sensitive Materials
Conventional thermal lasers scorch wood at the engraving edge, leaving dark carbonized lines that need sanding to remove. The photo pair below places a thermal-laser sample next to an F2 Ultra UV sample of the same jewelry-box design.
This clean-process behavior extends to soap, chocolate, lipstick, silicone, and ceramics — materials that would warp, melt, or discolor under a thermal beam.
UV vs Fiber vs CO₂
Desktop laser sources differ mainly by wavelength, spot size, and thermal behavior. At 355 nm, the UV source sits at the shortest wavelength of the three common types, giving the smallest achievable spot and the broadest material compatibility.
Construction & Hardware
Dual-Lens Optical System for Glass and Surface Work
No other desktop laser processes glass the way a UV source does. The F2 Ultra UV focuses its beam beneath the surface of glass blocks, crystal balls, and transparent acrylic to create permanent 3D subsurface engravings while the outer surface stays untouched, at speeds up to 180% faster than earlier UV machines.
Surface operations cover flat engraving, embossing, cutting, and rotary engraving up to 150 mm diameter. Two switchable field lenses — one for inner engraving (70 × 70 mm), one for surface work (200 × 200 mm) — let a single enclosure cover both workflows.
Tech Tip: Re-run the autofocus calibration in xTool Studio whenever you switch between the inner and surface engraving lenses — their focal lengths differ, and skipping recalibration produces permanent out-of-focus inner engravings. Keep the K9 calibration block from the inner engraving pack on hand for quick checks.
Dual-Camera Positioning System
The F2 Ultra UV integrates two 48 MP cameras working together for autofocus, automatic positioning, and real-time preview, reaching 0.2 mm positioning accuracy — 60% more precise than single-camera systems. A LiDAR ranging layer adds a second focus check on curved surfaces.
Precision Output for Jewelry and Microelectronics
A 0.001 mm vector resolution and a 0.00133 mm motion resolution in inner engraving mode produce detail comparable to industrial marking systems. The photo below shows text micro-engraved on a diamond ring stone, readable under magnification.
Physical Footprint & Connectivity
The standalone unit with touchscreen controller measures 294 × 429 × 520 mm and weighs 22.5 kg, fitting a standard workshop bench. USB, Wi-Fi, and direct IP connections mean no dedicated computer placement is required.
Software & Automation
xTool Studio converts flat photographs and text into printable 3D models automatically through built-in AI (Aimake integration). The workflow below turns a 2D photo into a 3D model, then into a finished inner-engraved glass block, without prior CAD experience.
The software runs on Windows and macOS, connects via USB, Wi-Fi, or IP, and accepts SVG, DXF, JPG, PNG, and BMP files for 2D work plus STL, OBJ, 3MF, and GLB for 3D projects.
Safety
The F2 Ultra UV ships pre-assembled and carries Class 4 laser safety certification, with an enclosed housing that contains beam scatter. An emergency auto-stop halts the laser immediately if the enclosure is interrupted. A fluid-dynamics-optimized airflow system controls operating temperature while keeping noise low, and enhanced sealing improves humidity resistance, rated for storage down to -10 °C and operation between 10 °C and 30 °C.
Certification & Compliance
Class 4 laser safety certification is the only confirmed compliance standard for this system. Buyers working under stricter workplace regulations should verify local laser-safety requirements before installation.
Applications
The 355 nm wavelength is absorbed by nearly all materials — including fully transparent acrylic, clear glass, and silicone — where CO₂ and fiber sources reflect or pass through without effect.
- Jewelry & watchmaking: Micro-engraves text and logos on watch movements, rings, and gemstones at 0.2 mm positional accuracy without damaging polished surfaces.
- Personalized gifts & drinkware: Produces burn-free engravings on glass bottles, champagne flutes, and ceramic mugs suited to premium retail pricing.
- Collectible crystal art: Creates 3D subsurface sculptures inside glass blocks and crystal balls using the 70 × 70 mm inner-engraving lens.
- Industrial marking: Marks chips, compass medallions, and metal components with micron-level detail suited to microelectronics traceability.
- Fashion & textile decoration: Etches denim, leather, and fabric patterns without the scorching typical of thermal laser sources.
- Signage & promotional products: Cuts and engraves acrylic business cards and keycap legends using the 200 × 200 mm surface field.
UV output commands premium pricing because no other desktop process matches this resolution, material range, and clean finish together.

How to Set Up the xTool F2 Ultra UV for First Use
This guide covers unboxing, connecting, and configuring the F2 Ultra UV from delivery to the first successful engraving job.
Step 1: Detach the Field Lens Protector
Remove the field lens protector before powering on; it ships installed to prevent transit damage. Leaving it in place blocks the beam and prevents engraving.
Step 2: Connect the Power Adapter and Install the Pipe
Connect the power adapter to the machine and attach the smoke exhaust pipe to the outlet. Route the pipe to an external vent or an approved air purifier (Safetypro AP2 or IF2 Inline Fan).
Step 3: Download and Install xTool Studio
Download xTool Studio for Windows or macOS from s.xtool.com/software. Connect the machine via USB and select it in the software's device list.
Step 4: Select the Correct Field Lens
Choose the surface engraving lens for flat material (200 × 200 mm field) or the inner engraving lens for 3D subsurface work (70 × 70 mm field). These lenses are not interchangeable with other F2 Ultra models.
Step 5: Place Material and Run Autofocus
Place material on the slatted panel for cutting, or on the base plate, using the L-shaped positioning piece for repeatable placement. Trigger autofocus in xTool Studio; the dual cameras and LiDAR set the focal distance automatically, then preview the job before starting.
Frequently Asked Questions — xTool F2 Ultra UV
Why only 5 W? Is that enough power for professional work?
5 W is the optimal power level for a desktop UV laser system. UV photons at 355 nm break molecular bonds through photochemistry rather than heat, so effective energy density exceeds what the wattage alone suggests. For 3D inner engraving in glass, the F2 Ultra UV typically runs at around 60% of maximum power, leaving headroom for demanding jobs.
What is included in the Inner Engraving Pack?
The Inner Engraving Pack contains an inner engraving lens, a riser, a K9 glass calibration block, and 3 calibration cards. The pack is pre-calibrated, so switching between surface and inner engraving modes needs no manual optical alignment.
Can the F2 Ultra UV field lenses be swapped with F2 Ultra lenses?
No, the two machines use different light sources, optical paths, and lens interfaces. Despite sharing the "F2 Ultra" series name, their field lenses cannot be interchanged, and using the wrong lens can prevent correct focus or damage the optics.
What accessories are compatible with the F2 Ultra UV?
Compatible rotary accessories include the RA3 and RA2 Pro. Automation options include the Auto Streamline Conveyor (extends the surface area to 200 × 500 mm) and a Pedal/Button Switch, alongside the Fire Safety Set, Safetypro AP2 Purifier, and Safetypro IF2 Inline Fan.
How do I clean the field lens and fan module?
If patterns look shallower than expected or cutting depth decreases, the field lens is likely contaminated. Clean it with a lint-free cloth moistened with isopropyl alcohol, and for the fan module, remove the magnetic guard, open the cover, and brush away accumulated dust.
Does the F2 Ultra UV require an inert gas atmosphere for engraving?
No, the F2 Ultra UV operates in normal ambient air for all supported materials, including glass, metal, and acrylic. Adequate smoke extraction via the exhaust port is recommended for materials that produce combustion by-products when cut.
