In order to increase patient safety, reusable medical parts must be provided with a UDI code (UDI – Unique Device Identification) which remains permanently legible even with heavy use and frequent cleaning. But also beyond legal requirements, manufacturers and users employ part markings for a reliable traceability. That’s why UDI codes or other labels can be found on almost all instruments, devices and accessories in medical technology.

Aluminum is often anodized, i.e. provided with a ceramic-like oxide layer to protect the material from abrasion or natural oxidation. The layer also has a decorative character, since it can be anodized in many colors.
CO2 or fiber lasers are suitable for labeling the anodized surface. Classically, the CO2 marking laser creates a bright lettering (by bleaching), while fiber laser systems mark dark as well as bright. In both cases, the effect brought about by the laser is a color change.
