Portable dual-laser (fiber + diode) for metal marking and fast engraving

Last updated June 1, 2026How we evaluate

Released May 2024

Fiber + diode in one desktop unit

The F1 Ultra switches between a fiber source (metal) and a diode source (wood/acrylic) inside one chassis. You do not swap a 10W diode for a 40W diode — that is the xTool S1 model.

Listed as hybrid because two laser technologies share one machine, not because you pick 10W vs 40W on the same diode head.

What this machine is for

Direct bare-metal marking for jewelry, tools & personalization

Reference benchmark same job size on every machine so you can compare times fairly.

Laser spot size

~0.02 mm fiber spot

Smaller spot = finer detail (frame motion is usually the same across tiers)

Motion precision: 0.00199 mm

Sample engrave job

~3–6 min

TL;DR

A compact desktop machine combining a 20W fiber laser and 20W diode. The fiber module marks bare metal — stainless steel, aluminum, brass — without spray. Ideal for jewelry, knives, and metal gifts. Premium price for a small work area.

What this machine is for

Materials

Engraves

· Stainless steel
· Aluminum
· Brass
· Gold-plated items
· Wood
· Leather
· Plastic (select types)

Cuts

· Thin wood/leather (diode only, limited)

Cannot do

· Thick material cutting
· Large signage (work area too small)
· Clear acrylic (diode)
· Deep CO₂-style cuts

Pros

✓Marks bare metal directly — no chemical spray needed on fiber
✓Extremely fast fiber engraving for production
✓Compact and portable compared to open-frame diodes
✓Dual laser covers both metal and organic materials
✓Optional conveyor for batch metal marking

Cons

✗Small default work area — not for large signs or panels
✗Very expensive for the cutting/engraving area you get
✗Not a replacement for a CO₂ if you cut acrylic or large wood
✗Fiber and diode require switching modules (not simultaneous)
✗Enclosed but still requires proper ventilation for some materials

Beginner notes

Buy this if metal is your main material — rings, dog tags, tools, tumblers with stainless sleeves. Do not buy it as your first general-purpose laser; the work area is too small for typical hobby projects like large wood signs.

Pro tips

Use the fiber module for all metal work. The diode is a bonus for wood/leather on the same desk. Rotary attachment is essential for rings and cylindrical metal. Dial in power/speed on scrap — fiber is unforgiving on thin metal.
