cab marking lasers are primarily used for the processing of metal and plastic parts. Different methods are commonly used depending on the requirement and material.
Ablation of the material through evaporation with very high energy density that produces a deep marking with contour sharpness. An additional color change depending on the alloy or chemical composition improves the readability of the marking contents.

Is mainly used with high-alloy, stainless steels and with titanium. Laser annealing creates a color change when the material is selectively exposed to heat and oxygen without noticeable material ablation.
Traceability in sterilization processes
The laser marker removes top coating to show a different-colored material underneath. Examples: top coatings or anodizing layers, laser label material or day and night design on control buttons
Is used for the processing of plastic material. The color change depends on the chemical composition of the material and additives. Destroying color pigments and creating gas-bubbles within the material produces light marks. Carbonization produces dark marks.
Size allocation in medical technology
The laser beam melts the workpiece surface locally. Small gas bubbles increase the volume of the molten material producing a raised marking. Small gas bubbles within the material diffusely reflect the light.
