xTool F2 Ultra UV $3999.99 For years, engraving on glass and crystal has been one of the most frustrating challenges in the laser world. Diode lasers can’t touch transparent materials. CO₂ lasers leave rough, frosted surfaces. And even high-end fiber lasers struggle to produce clean results on heat-sensitive materials like certain plastics.
The xTool F2 Ultra UV was designed to solve this problem entirely. While it shares a name and chassis with its powerful MOPA fiber sibling, this machine is a different animal altogether. Powered by a 5W 355nm UV laser, it brings “cold” photochemical processing to the desktop — engraving and cutting without the heat, burn marks, or charring that plague other laser types.
Released in late 2025, the F2 Ultra UV is xTool’s specialized answer to the question: “What if I need to engrave glass, crystal, and sensitive plastics with museum-grade detail?” It’s a niche machine, but within that niche, it’s virtually peerless.

Cold UV Processing: No Heat, No Burns
The F2 Ultra UV operates at 355nm — deep in the ultraviolet spectrum. Unlike blue diode lasers that rely on thermal ablation, UV lasers use high-photon-energy beams that break molecular bonds directly.
As one reviewer noted: “The UV laser doesn’t cut by burning so much as wobbling the molecular structure of the paper apart”. This makes it ideal for materials that would be ruined by the heat of other lasers.
3D Inner Engraving: Magic Inside Glass
The F2 Ultra UV’s headline capability is 3D subsurface engraving — creating three-dimensional images that appear to float inside crystal, glass, and acrylic.
This dual-lens approach means the same machine can produce internal crystal sculptures and precise surface engravings on flat materials.
Blazing 15,000 mm/s Speed
The F2 Ultra UV shares the same 15,000 mm/s galvo speed as its MOPA sibling. The galvanometer system uses two high-speed mirrors to direct the laser beam — no heavy gantry, no mechanical lag.
Wood and Paper: Clean, Burn-Free Results
The UV laser cuts paper with no burning edges and engraves wood without charring. It’s not as fast as a 60W blue diode for thick wood cutting, but for detailed engravings and thin materials, the clean results are unmatched.
Metals: Surface Marking Only
Important caveat: The F2 Ultra UV does not cut metal. For deep engraving on brass, steel, or aluminum, the F2 Ultra is the right choice. The UV model is for surface marking and fine detail work on metals, not cutting or deep engraving.

Comparisons: F2 Ultra UV vs. F2 Ultra (MOPA)
The naming can be confusing. Here’s how they differ:
| Feature | F2 Ultra UV | F2 Ultra (MOPA) |
|---|---|---|
| Laser | 5W UV (355nm) | 60W MOPA Fiber + 40W Diode |
| Best For | Glass, crystal, sensitive plastics | Metals, wood, acrylic |
| Metal Cutting | No | Yes — up to 2mm steel |
| 3D Inner Glass | Yes — unique capability | No |
| Price | $4,599 | $5,549 |
The choice is simple: if you need glass and crystal inner engraving, choose the UV. If you need metal cutting and deep metal engraving, choose the MOPA. If you need both, you may need both machines.
Summary
The xTool F2 Ultra UV is a specialized precision instrument that does one thing exceptionally well: cold UV processing of glass, crystal, and sensitive materials. Within that niche, it has no real competitor at the desktop level.
The 3D inner engraving capability is the headline feature — creating floating sculptures inside crystal that were previously the domain of expensive industrial systems. The cold processing delivers burn-free results on materials that would be ruined by other lasers. And the micron-level precision ensures museum-quality detail.
Is it perfect? No. At $4,599, it’s a serious investment. The 5W power is modest for cutting thick materials. And if you don’t work with glass, crystal, or sensitive plastics, the machine is overkill for your needs.
But for glass artists, jewelry designers, small businesses producing crystal awards, and creators working with heat-sensitive materials, the F2 Ultra UV offers a combination of capability and precision that is genuinely unmatched at this price point.
