A fiber laser engraver creates a 1064nm beam in an optical fiber to permanently mark and engrave metal (and many plastics). Learn what it is, how it differs from CO2, and what it’s for.

A fiber laser engraves metals – steel, stainless, aluminum, brass, copper, titanium, gold, silver – and marks many plastics. It can’t engrave clear glass or acrylic, and wood is poor.

Technically yes, but it’s not recommended. Fiber’s 1064nm wavelength is poorly absorbed by wood, so it scorches and risks fire instead of marking cleanly. Use a CO2 laser for wood.

Not clear acrylic – the 1064nm beam passes through it. A fiber laser can mark some dark or pigmented plastics, but for acrylic use a CO2 laser. Here’s the breakdown.

No – a fiber laser can’t engrave clear glass. Its 1064nm beam passes straight through it without leaving a mark. Use a CO2 laser to engrave glass; here’s why.

Yes – a kilowatt-class fiber laser cutter cuts metal cleanly. But fiber markers (20-100W) only mark; they don’t cut. Learn the difference and what power cuts which thickness.
