A fiber laser is the tool for marking and engraving bare metal: stainless steel, brass, titanium, aluminum, gold and silver. This guide is for jewelry makers, Etsy sellers and small shops choosing a desktop or handheld fiber marker, and it compares six machines from 10W to 100W on the numbers that decide what they can do: source power, lens field, rotary support, and what each listing actually says about safety and warranty.

How we scored them
Each machine is scored out of 100 on performance, build, value, safety and warranty, with the weights published on our How We Pick page. A spec the listing does not publish scores nothing.

What the listings tell you, and what they leave out
We read 16 fiber laser listings for this guide. Only 4 stated a warranty term, and only 4 printed an FDA accession number, the registration number a laser maker files with the FDA’s Center for Devices and Radiological Health. Two of those four were GWEIKE models sharing the same number. 11 of the 16 stated a laser class, but three of those stated a class that does not fit a marking laser: two said Class 1 next to a milliwatt output figure, and one said Class 5, which does not exist.
Treat every machine here as a Class 4 laser unless the label on the machine itself says otherwise.
Buying guide: choosing a fiber laser engraver
Fiber vs MOPA
A standard fiber source (often called Q-switched) marks metals in black, gray and white and engraves depth with repeated passes. A MOPA source lets you change the pulse width, which is what makes color marking on stainless steel and titanium and clean black marks on anodized aluminum possible. If you only need text and logos on tags and tools, a standard fiber source does the job for less.
Watts and depth
On a fiber laser the wattage is optical output from the source, not electrical input, so the numbers compare directly. More power mainly buys speed on deep and 3D engraving. A 20W machine marks a dog tag quickly; a 50W or 60W machine finishes deep engraving and thin sheet cutting in far fewer passes.
Lens field
Fiber lasers mark through a galvo head and a fixed lens, so the lens sets the work area. A 110 x 110 mm lens gives the finest detail. Larger lenses (150, 200 or 300 mm) cover bigger parts but spread the energy, which is why Monport describes 150 x 150 mm as the right size for a 60W source.
Rotary for rings and tumblers
Round items need a rotary axis. Two picks include one (SFX and Monport) and the ComMarker supports one sold separately. If tumblers are your main product, see our tumbler material notes.
What a fiber laser will not do
Fiber lasers are poor at wood, clear acrylic and glass, and the desktop machines here do not cut sheet material beyond thin metal. If you work mostly with wood, leather or acrylic, a diode or CO2 machine fits better. The Machine Finder walks through the choice.
Fiber lasers emit invisible infrared light at about 1064 nm, and polished metal reflects it. Wear glasses rated with an optical density (OD) for 1064 nm, shield the beam path, never leave a job running unattended, and vent fumes from coatings and plastics. Never mark PVC. See the FDA guidance on laser products and OSHA laser hazards.
Frequently Asked Questions
Can a fiber laser engrave wood?
It can mark some woods, but poorly. The 1064 nm wavelength is absorbed far better by metal than by wood. For wood, a diode or CO2 laser is the better tool.
What is the difference between a fiber and a MOPA laser?
Both are fiber lasers. A MOPA source adds adjustable pulse width, which enables color marking on stainless steel and titanium and black marking on anodized aluminum.
Can a desktop fiber laser cut metal?
Only thin sheet. The xTool F2 Ultra Single listing rates 2 mm metal cutting, and the Monport listing says “some metal sheet cutting”. These are marking machines first, not sheet metal cutters.
Do I need special safety glasses for a fiber laser?
Yes. Glasses must be rated with an optical density for 1064 nm. Glasses made for blue diode lasers do not protect against fiber laser light. The ComMarker B4 and GWEIKE G2 Max listings include glasses.
What does an FDA accession number mean?
It is the number the FDA assigns when a manufacturer files a report on a laser product. It shows a report was filed; it is not an FDA approval. Four of the 16 listings we read printed one.
