CerMark is the industry-standard solution for laser-marking metal. You apply the spray or paste to the metal surface, engrave with your laser, and the heat bonds a permanent black mark to the metal — without needing a fiber laser. Works on stainless steel, titanium, chrome, brass, and more with a CO2 or diode laser. If you want to offer engraved tumblers, knives, or metal gifts without a fiber laser investment, CerMark is how you do it. Widely used and well-documented in the maker community.
