What types of materials can be marked with a laser?
The answer depends on the wavelength of the laser used. Fiber lasers can be used to mark metals with a nice black mark. Pretreating the surface of the material is not necessary saving time and cost of additional chemicals. You can also create a deep mark into the metal, or create a frosted look which is a lighter mark. With a CO2 laser wood, acrylic, glass, and stone can be marked.
