xTool F1 Ultra Review: Is It the Best Fiber Laser Engraver for Small Business?

Who the xTool F1 Ultra Is Built For

The xTool F1 Ultra is aimed at a specific type of small business owner: someone who works across multiple materials and currently either owns multiple machines or avoids certain jobs because their single engraver can't handle them. Jewellers who want to engrave metal and wood in the same session. Custom gift makers who personalise everything from keychains to cutting boards. Product sellers who want to add metal business cards or dog tags to their catalogue without buying a dedicated metal engraver.

The dual-laser design is the entire value proposition: instead of choosing between a fiber laser for metals and a diode laser for non-metals, the F1 Ultra runs both, automatically switching between them depending on the job.

Before this review, it's worth clarifying what the F1 Ultra is and what it isn't. It's an engraver — a galvo-mirror laser engraving and cutting machine — not a welder. It doesn't join metal; it marks, engraves, and cuts thin stock. This places it in a different category from the fiber laser welders reviewed elsewhere on this hub, but many of the same small business buyers considering a laser system investment will encounter both product categories. For the questions around whether a fiber laser system in general makes sense for your specific application, see our MOPA vs standard fiber laser guide for the technology context.

What's in the Box and First Impressions

The F1 Ultra ships with: the machine itself, a touchscreen controller, power adapter and cable, two safety lock keys (the machine won't fire without both keys inserted), exhaust pipe, slatted panel, L-shaped positioning piece, a material sample pack, user manual, and lint-free cleaning cloth.

The machine footprint is 10.75" × 14.69" × 19.37" (approximately A3 paper size footprint, tall enough to be noticeable on a desk but not imposing). The fully enclosed acrylic lid is required for operation — it provides eye protection from both the 455nm diode (visible blue light) and the 1064nm fiber IR laser.

Build quality matches what xTool has established across their product line: solid aluminium construction, well-fitted panels, quality cable management. The machine feels like a professional instrument rather than a prosumer gadget, which matters when you're using it in a client-facing studio or alongside premium products.

Key Specs: What They Mean in Practice

Dual 20W Fiber + Diode Laser

The F1 Ultra is billed as the world's first 20W fiber and 20W diode dual laser desktop engraver — a marketing claim that appears accurate as of its 2024 launch. Both lasers are at the high end of what desktop-class fiber and diode machines achieve.

20W fiber laser (1064nm infrared): The fiber laser is an infrared laser using a fiber (diode-pumped fiber) as the gain medium — a genuine fiber laser, not a diode at a different wavelength. This is confirmed by xTool: "The F1 Ultra uses an IR laser as its laser source, while the fiber serves as the gain medium." The 1064nm wavelength is standard for metal engraving and marking — it's absorbed by metals where visible wavelength lasers reflect. At 20W, this is meaningfully more powerful than the 2W infrared found in the smaller F1 — 10× the power in the same wavelength category.

20W diode laser (455nm blue): The diode laser is a 455nm blue laser at 20W — at the top end of desktop diode laser power. Blue diode lasers at 455nm are effective on wood, leather, acrylic, and most non-metal materials. At 20W with galvo speed, this is among the most powerful desktop diode configurations available.

Automatic switching: The machine automatically selects the appropriate laser for the material rather than requiring manual mode switching. Set up the job, the machine handles laser selection.

Working Area and Conveyor System

The standard working area is 220×220mm (8.66" × 8.66") — described by xTool as the largest working area among desktop galvo laser engravers. Galvo lasers inherently have a constrained working area because the mirrors directing the beam can only deflect so far; increasing area requires additional optics and compromises detail quality at the edges. xTool uses microbeam technology to maintain detail quality across the full 220mm field.

With the optional conveyor extension, the effective processing length extends to approximately 500mm × 220mm (19.7" × 8.66") — the machine can process longer materials by automatically advancing them through the work area. For production runs of tumblers, long boards, or extended strips, the conveyor extends what would otherwise be a size-limited machine.

The Auto Streamline™ production feature allows the machine to automatically orient designs to fit a material and queue batch jobs — reducing the manual labour of positioning multiple items for repetitive production.

Camera, Autofocus and Software

The F1 Ultra includes a camera system for preview alignment — you see a camera view of the working area on screen and can position designs precisely relative to the material. This is particularly useful for batch jobs where material positioning varies slightly between pieces.

Autofocus: the machine maintains focus across 3D curved surfaces — an important capability for engraving on tumblers, rounded metal surfaces, and irregular objects where a flat-field focus assumption would cause quality degradation at the edges.

The software is xTool's XCS (xTool Creative Space) — the same software used across xTool's MetalFab and other products. 50+ xTool demo rooms across the US provide hands-on access before purchase, which is a meaningful commitment for a desktop laser at this price tier.

Real-World Performance Testing

Metal Engraving: Stainless Steel, Aluminum, Brass

The fiber laser at 20W performs genuine metal marking and engraving — deep, permanent marks on stainless steel, aluminum, gold, silver, iron, platinum, and brass. The machine is capable of:

• Deep engraving: Creating depth on metal surfaces, not just surface oxide marks
• Embossing/relief: 3D embossing effects on metal using varying power levels
• Colour engraving on stainless steel: Using fiber laser oxidation to create colour variation — black, grey, gold, and other tones depending on power and speed settings
• Thin metal cutting: 0.4mm brass sheet, 0.3mm stainless steel, 0.2mm aluminium

The speed at which these results are produced is the machine's genuine selling point. A metal business card engraves in approximately 5 seconds. A full-name custom dog tag at production-batch settings: seconds per unit. For small businesses selling personalised metal items in quantity, this speed at desktop scale is commercially significant.

On stainless steel specifically, the fiber oxidation color engraving produces results that previously required specialised settings knowledge or MOPA laser technology. At 20W with the correct speed and frequency settings, the F1 Ultra achieves this in the standard fiber mode — accessible to operators who aren't laser engineers.

Diode Laser: Wood, Leather, Acrylic

The 20W 455nm diode laser handles the material set that fiber can't: wood, acrylic, leather, paper, glass, ceramic, slate, and similar non-metallic materials.

Benchmarks from testing and community reviews:

• Leather patch (logo engraving): approximately 6 seconds
• Paper card: approximately 1 second
• Acrylic cutting (12mm max): multiple passes at full power
• Wood cutting (15mm max): multiple passes

On black acrylic specifically, community reviews note results described as magic — the 20W diode on black acrylic produces exceptionally clean, high-contrast results for signage and decorative work. On natural wood, the high power and galvo speed combination allows fine detail at production speeds uncommon at the desktop level.

The 20W diode also handles laser rust removal at low power settings — tested at 20% power, 600mm/s, removing thick rust in two passes without surface damage. For restoration and repair businesses adding rust removal to their service offering, this is a secondary capability worth knowing.

Speed and Batch Production

10,000 mm/s maximum engraving speed is the headline spec — and it's meaningful in practice. This is 2.5× faster than the smaller F1 (4,000 mm/s) and exceeds most desktop laser engraver claims.

At this speed, the machine's production economics change. A business selling personalised ornaments at a craft fair can process 6 pieces per minute in batch mode. A jewellery seller adding custom engraving to metal pieces can turn around 10–15 pieces in the time a slower machine completes one.

The Auto Streamline™ system adds to this: it intelligently queues multiple items, adjusts for material positioning variations via the camera system, and runs batches with minimal operator intervention between pieces.

Where the F1 Ultra Excels

Dual-material businesses. The F1 Ultra's dominant use case is any business that works across both metals and non-metals in the same workflow. If you're selling custom wooden coasters AND personalised steel keychains, you previously needed two machines. The F1 Ultra handles both without reconfiguration.

High-speed batch production. At 10,000 mm/s with Auto Streamline™, the F1 Ultra is genuinely fast for desktop-class production. For craft fair sellers, Etsy businesses with consistent product lines, and corporate personalisation services, the throughput is commercially relevant.

Jewellery and small metal work. Deep metal engraving, embossing, and colour engraving at desktop scale. The combination of 20W fiber power and galvo precision makes this a capable jewellery laser for personalisation, repair restoration documentation, and custom design work.

3D curved surface engraving. Tumblers, bottles, rounded handles, and non-flat surfaces that require focus-following technology to maintain consistency across the curve. At this price tier, this capability is rare.

Compact footprint for client-facing studios. The enclosed design, professional build quality, and desk-sized footprint suit studios where clients visit or where the machine occupies shared space.

Where It Falls Short

Not a welder. The fiber laser is 20W — adequate for engraving, marking, and cutting thin metal sheet (under 0.5mm). It cannot weld metal. If your application is joining metal parts, this is not the right tool category. For laser welding, see our separate comparison of the xTool F1 Ultra vs ComMarker B6 which covers the engraver side, and the welding hub for the right machine category.

Thin metal cutting only. The 0.3–0.4mm maximum metal cutting thickness is genuinely thin. For fabricators who need to cut metal components, this is a limitation — production metal cutting requires a different machine entirely (like the xTool MetalFab's CNC cutting system).

Working area is fixed at 220×220mm without the conveyor. For large-format work, the conveyor extension adds cost and the effective area is only expanded in one dimension. Very large single-piece work (large plaques, wide boards) can't fit without tiling.

Premium pricing. The F1 Ultra is at the higher end of desktop laser pricing. For businesses whose work is exclusively wood and non-metals, a 20W diode-only machine at lower cost would cover the application. The dual-laser premium is only rational if you use both.

Who Should Buy the xTool F1 Ultra?

The F1 Ultra is the right choice for:

Small businesses working across metal and non-metal. If your product line includes both metal personalisation and non-metal engraving/cutting, the F1 Ultra's dual-laser design eliminates the need for two separate machines.

Jewellers and personal accessory businesses. Metal engraving at production speed, embossing capability, colour engraving on steel — the F1 Ultra is a professional tool for the jewellery and accessories market.

High-volume production at desktop scale. The 10,000 mm/s speed and Auto Streamline™ batch system suit sellers doing consistent product lines in volume — tumblers, ornaments, keychains, business cards, tags.

Studios with limited space. The enclosed desktop footprint and professional appearance make it appropriate for client-visible or shared studio spaces.

Who Should Look Elsewhere?

Businesses working exclusively with wood, acrylic, and leather. A 20W diode-only desktop laser covers this material set at lower cost. The fiber laser premium is wasted if you never engrave metal.

Fabricators who need to cut metal above 0.5mm. The F1 Ultra's 0.3–0.4mm metal cutting limit rules it out for production metal cutting. The xTool MetalFab or a dedicated fiber CNC laser cutter is the correct tool for this application.

Buyers looking for a portable event laser. The F1 Ultra is a desk-based enclosed machine — not designed for transport to craft fairs. The smaller F1 (2W infrared + 10W diode, 4,000 mm/s) is the portable craft fair alternative.

Professional metal engravers at high volume. At 20W the fiber laser is capable but sits below the 50–100W+ fiber sources used in production metal engraving shops where deep engraving at high throughput is the primary application. For guidance on what parameters actually matter for metal engraving, see our how to laser engrave metal guide.

Final Verdict

The xTool F1 Ultra is a genuinely impressive desktop laser for what it's specifically designed to do: high-speed engraving and cutting across metal and non-metal materials in a compact, enclosed, production-ready platform. The dual 20W laser combination is the first of its kind at the desktop scale, and the 10,000 mm/s speed is commercially relevant for batch production.

For small businesses that work across materials and need production speed at desktop scale, it's among the most capable machines in its class. The main question before buying: do you actually need both the fiber and the diode laser regularly? If yes, the F1 Ultra is difficult to beat at this price tier. If your work is single-material, a simpler machine likely covers your needs at lower cost.

Frequently Asked Questions

What is the xTool F1 Ultra?

The xTool F1 Ultra is a desktop dual-laser engraver and cutter combining a 20W fiber laser (1064nm infrared) and a 20W diode laser (455nm blue) in one enclosed unit. It engraves and cuts metals (stainless steel, aluminium, brass, gold, silver, iron, platinum), wood, acrylic, leather, glass, ceramic, slate, and plastics — automatically switching between the two laser sources based on the material. It runs at up to 10,000 mm/s using galvo mirror scanning, with a 220×220mm work area expandable to approximately 500×220mm with the conveyor extension.

Can the xTool F1 Ultra engrave metal?

Yes — the 20W fiber laser (1064nm) is specifically designed for metal engraving and marking. It engraves stainless steel, aluminium, brass, copper, gold, silver, iron, and platinum with high clarity and depth. At 20W, it also produces colour engraving on stainless steel via laser oxidation (creating black, grey, gold, and other tones depending on parameters). For cutting, it handles 0.3mm stainless steel, 0.4mm brass, and 0.2mm aluminium sheet. Deep engraving and 3D embossing on metals are both within its capability.

How fast is the xTool F1 Ultra?

The F1 Ultra engraves at up to 10,000 mm/s maximum speed using galvo mirror scanning — 2.5× faster than the smaller F1 (4,000 mm/s). At production settings, a leather patch takes approximately 6 seconds, a metal business card approximately 5 seconds, and a paper card approximately 1 second. For batch production, the Auto Streamline™ system queues multiple items and optimises positioning via the camera system, further reducing per-unit time.

What is the difference between the xTool F1 and F1 Ultra?

The xTool F1 is the smaller, portable version: 2W infrared laser + 10W diode laser, 4,000 mm/s maximum speed, more compact form for portability to craft fairs and events. The F1 Ultra is the larger, higher-power production machine: 20W fiber laser + 20W diode laser, 10,000 mm/s (2.5× faster), 220×220mm work area (the largest desktop galvo area), and conveyor extension capability for longer materials. The F1 Ultra is significantly more capable for production and metal work; the F1 is more portable and lower cost.

Is the xTool F1 Ultra worth the price for small business?

For businesses working across both metal and non-metal materials in their product line: yes. The dual 20W laser combination eliminates the need for two separate machines (a fiber laser for metal and a diode laser for non-metals), and the 10,000 mm/s speed with Auto Streamline™ production provides commercially relevant throughput for batch orders. For businesses working exclusively with wood, acrylic, or leather: a 20W diode-only machine at lower cost covers the application, and the fiber laser premium isn't justified.
