Diode vs CO2 vs Fiber Laser Engraver: Which Type Do You Actually Need?

Mon, 27 Apr 2026 00:00:00 +0000

Most people shopping for their first laser engraver hit the same wall: they don’t know what type of laser they’re even buying. Diode, CO2, fiber — the listings use these words freely, but nobody explains what actually changes between them or why it matters for your specific project.

We’ve tested machines across all three categories — from entry-level diode open-frames to production-grade CO2 systems to galvo fiber units built for metal marking. The short version is this: the right laser type is determined almost entirely by the materials you plan to work with. Get that decision wrong, and no amount of power or features will compensate.
