The xTool F1 Ultra is a professional-grade portable galvo laser engraver combining a 20W fiber laser and a 20W diode laser in a single compact unit. Where the standard F1 pairs a 10W diode with a 2W IR laser, the F1 Ultra doubles the power on both channels — delivering the fiber laser capability previously reserved for industrial bench-top machines in a 3 kg form factor that runs on USB-C power.

Fiber Laser vs Diode — What Each Does

The 20W fiber laser (1064nm) is the defining upgrade over the standard F1. Fiber lasers interact with metals at a wavelength optimised for metal absorption — marking stainless steel, titanium, brass, copper, gold, silver, and aluminium with deep contrast and high permanence. The 20W fiber laser also performs colour engraving on stainless steel (oxidation-based colour marking), produces deep annealing marks on tool steel, and marks ceramics and hard plastics with precision. At 10,000 mm/s, it processes metal batches at a speed that makes it viable as a production tool, not just a sample machine.

The 20W diode laser (455nm) handles organic materials: wood, leather, acrylic, cork, bamboo, paper, and fabric — the same class of materials the standard F1's diode covers, at higher power for faster throughput and deeper cutting.

Colour Engraving on Stainless Steel

One of the fiber laser's capabilities that has no equivalent in diode engraving is colour marking on stainless steel. By controlling the laser pulse frequency and power precisely, the fiber laser creates a thin oxide layer on the steel surface that produces visible colour — blue, gold, purple, and other tones — without pigments or coatings. The result is permanent, scratch-resistant colour that is used for branded surgical instruments, premium cutlery, architectural fixtures, and luxury goods.

10,000 mm/s — Production-Grade Speed

At 10,000 mm/s, the F1 Ultra processes jobs roughly 2–3× faster than the standard F1 and 10–20× faster than a gantry laser at equivalent quality. For a personalisation business engraving metal items — tags, jewellery, tools, trophies, cutlery — this translates directly to throughput that can sustain commercial production volumes from a desktop machine.

Who It's For

• Jewellers and metalworkers who need a fiber laser for deep metal marking, colour engraving, and precious metal work
• Trophy and award makers engraving stainless steel and aluminium plaques at production volume
• Industrial part marking — serial numbers, QR codes, and compliance marks on metal components
• Premium personalisation businesses working with high-value metal items
• Studios that need fiber capability in a portable, compact form factor
