Ceramic Foam Overview
Ceramic foams are a high porosity cellular structure of open-cell or closed-cell foam typically composed of aluminum oxide, titanium oxide, silicon carbide, zinc carbide, or boron carbide. Laser processing of ceramic foam can be performed with either a 9.3 or 10.6 micron CO2 laser and the 1.06 micron fiber laser. Laser engraving of ceramic foam with a 1.06 micron fiber laser produces some depth that can be lighter or darker depending upon the substrate processed. Laser marking of ceramic foams is possible with a CO2 laser and creates a bleached mark of little contrast. Laser marking of ceramic foam is also possible with the 1.06 micron fiber laser with the presence of certain additives in the ceramic and produces a dark mark on the surface of the material. Laser cutting of ceramic foams is not possible with the CO2 or fiber lasers.
