xTool F2 Ultra UV Laser Engraver: 5W UV, glass and crystal, specs

The xTool F2 Ultra UV is a compact, enclosed desktop laser engraver built around a 5W ultraviolet laser. It is designed for materials that other lasers handle poorly, including glass, crystal, acrylic and ceramics, and it can engrave inside glass as well as on the surface. This page explains what the main specs mean and what to consider before choosing one.

Why a UV laser

Most hobby lasers work by heating the material. A UV laser works with a much shorter wavelength, and xTool calls it a cold light source. In general, that means less heat spreads into the surrounding material, which suits transparent, heat-sensitive and fragile items. xTool says the result is clean edges without charring, burning or yellowing, and no need for pre-coating or polishing.

Spot size and precision

The listing gives the UV spot size as smaller than 10 microns, which is a fraction of the width of a human hair. A smaller spot typically means finer lines and more detail in small text, logos and photographs. xTool says this precision exceeds standard CO2 lasers.

Engraving inside glass

The headline feature is 3D engraving inside glass and crystal, where the laser focuses beneath the surface to form a design within the material. xTool pairs this with software that generates 3D from 2D images, so no modelling skills are needed. Typical projects are crystal trophies, glass gifts and personalised bottles. The laser can also do surface engraving, embossing, cutting and rotary engraving.

Materials

The 5W UV source is listed as processing crystal, glass, acrylic, ceramics and plastic, among others. Results vary by material, so it makes sense to test on offcuts and check xTool's settings for each one.

Cameras and speed

Two 48MP cameras provide autofocus and alignment, so you can position a design on the actual piece. Marking speed reaches 15,000 mm/s, which xTool says helps with batch production and larger orders. The machine accepts accessories, including a conveyor for batch processing and a rotary for 360° engraving on curved items such as tumblers.

Size and enclosure

The listing gives dimensions of 11.6 x 16.9 x 20.5 inches and a weight of 49.6 lb. The fully enclosed body is described as suitable for tight spaces and for on-the-spot customisation at craft fairs. It is a Class 4 laser with 5,000 mW output, so use it exactly as the manual says, including any eye protection and ventilation guidance.

Who it suits

It suits makers and small businesses producing personalised glassware, trophies, gifts and jewellery-sized items. Anyone who mainly cuts thick wood or acrylic would typically look at a CO2 or diode machine, as a UV laser is chosen for fine marking rather than heavy cutting.

What to check before you buy

• Materials: confirm the glass, crystal or plastic you plan to use is supported, and that you can source blanks that suit inner engraving.
• Accessories: the conveyor and rotary are extras. The listing says the box holds the machine and a base material kit.
• Weight and space: at 49.6 lb, you will want a stable bench.
• Software: check the system requirements and file formats, and how 2D-to-3D conversion works.
• Fumes and upkeep: read the manual on ventilation, lens care and cleaning.
