xTool F2 Ultra UV Laser Engraver – Professional Marking Solution

xTool F2 Ultra UV is a 5 W, 355 nm UV galvanometer laser engraver built for micron-level precision engraving and cold-processing of glass, crystal, acrylic, ceramic, metal, wood, and virtually any material. With a 0,001 mm vector-fitting resolution, dual 48 MP cameras delivering 0,2 mm positioning accuracy, and a maximum processing speed of 15.000 mm/s, it handles both 3D inner engraving (70 × 70 mm field) and surface engraving (200 × 200 mm) from a single desktop enclosure — pre-assembled and ready to operate via xTool Studio on Windows or macOS.

Why UV at 355 nm Changes Everything

Most desktop lasers operate in the infrared spectrum — they cut and engrave by generating heat. A 355 nm UV laser operates differently: its high-energy photons break molecular bonds directly, with almost no thermal transfer to surrounding material. This is called cold processing, and it explains why the F2 Ultra UV produces burn-free edges, needs no pre-coating or post-polishing, and works cleanly on heat-sensitive substrates that would be destroyed by CO₂ or fiber alternatives.

The spot size of the UV source measures 0,02 × 0,02 mm — over 100× smaller than a CO₂ spot. That physical advantage, combined with the 0,001 mm vector resolution, is what makes it possible to engrave text as small as 0,3 mm, mark watch movements and chips with 0,2 mm positional accuracy, and produce 3D subsurface sculptures inside glass blocks with museum-grade sharpness.

Cold Processing: No Burns, No Cleanup, One Step

The comparison below illustrates what cold processing delivers on wood. The left sample was engraved with a conventional thermal laser — note the dark, scorched edges. The right sample was engraved with the F2 Ultra UV: identical design, clean relief texture, zero charring. No masking tape, no chemical treatment, no sanding required.

This clean-process behaviour extends across the material range: soap, chocolate, lipstick, silicone, and ceramics — all materials that warp, melt, or discolour under heat — engrave with precision and no surface damage.

UV vs Fiber vs CO₂: Choosing the Right Source

The chart below positions the three main desktop laser types by wavelength, spot size, material affinity, and thermal behaviour. At 355 nm, the UV laser occupies the shortest wavelength — smallest achievable spot, broadest material compatibility, and the only source capable of cold processing.

Master of Glass: 3D Inner Engraving and Surface Work

No other desktop laser handles glass like a UV source. The F2 Ultra UV focuses the beam beneath the surface of glass blocks, crystal balls, and transparent acrylic to create permanent 3D subsurface engravings — the outer surface remains entirely untouched. Speed is up to 180% faster than traditional UV machines. The result is a collectible-grade product that requires no protective finishing.

Surface operations are equally capable: flat engraving, embossing, cutting, and rotary engraving up to 150 mm diameter. Two switchable field lenses — one optimised for inner engraving (70 × 70 mm), one for surface work (200 × 200 mm) — let a single machine cover both workflows without any mechanical modification.

From 2D Image to 3D Crystal: One Software, No Modelling Skills

xTool Studio converts flat photographs and text into printable 3D models automatically using built-in AI. The workflow shown below takes a 2D image, generates a 3D model via Aimake integration, and delivers a finished 3D inner-engraved glass block — all without prior CAD or modelling experience.

Dual 48 MP Cameras: 0,2 mm Hawk-Eye Positioning

The F2 Ultra UV is the first desktop UV laser to integrate two 48 MP cameras simultaneously. Working in tandem, they handle autofocus, automatic positioning, and real-time preview — achieving 0,2 mm positioning accuracy, which is 60% more precise than single-camera systems. LiDAR ranging adds a second verification layer for accurate focus on curved and irregular surfaces.

Micron Precision for Jewellery, Watch Parts, and Microelectronics

A 0,001 mm vector resolution and 0,00133 mm motion resolution (inner engraving mode) produce detail that rivals industrial marking systems. The image below shows text micro-engraved on a diamond ring stone — the inscription remains clearly readable under magnification while the gemstone surface is undamaged.

Material Versatility: What Other Lasers Cannot Reach

The 355 nm wavelength is absorbed by nearly all materials — including fully transparent acrylic, clear glass, and silicone — where CO₂ and fiber sources simply reflect or pass through without effect. The collage below shows a cross-section of commercial applications processed on the F2 Ultra UV: keyboard keycap legends, green acrylic business cards, metal compass medallions, denim fabric patterns, ceramic mugs, glass spirits bottles, and silver jewellery.

High-Value Output: Premium Products, Maximum ROI

UV laser output commands premium pricing precisely because no other desktop process achieves the same combination of resolution, material range, and clean finish. The examples below represent the commercial output profile: personalised crystal photo blocks, engraved metal rings, feather-etched champagne flutes, 3D crystal balls, and resin pendants — all finished to a quality level that justifies high unit prices.

Safe by Design, Ready from Unboxing

The F2 Ultra UV ships pre-assembled. Class 4 safety certification applies, with an enclosed housing that contains all beam scatter. An emergency auto-stop function halts the laser immediately on enclosure interruption. The fluid-dynamics-optimised airflow system maintains operating temperature efficiently while keeping acoustic output low. Enhanced laser sealing provides improved humidity protection, rated for storage down to -10 °C and operation from 10 °C to 30 °C.

The standalone unit with touchscreen controller is shown below. The compact footprint (294 × 429 × 520 mm, 22,5 kg) fits on a standard workshop bench. Connection options include USB, Wi-Fi, and direct IP — no dedicated computer placement is required.

Tech Tip: When switching between the inner engraving lens and the surface engraving lens, always re-run the autofocus calibration in xTool Studio before your first job. The two lenses have different focal lengths; skipping recalibration results in out-of-focus inner engravings that are permanent and cannot be corrected. Keep the K9 calibration block from the inner engraving pack on hand for quick verification.
