Medical Device Laser Marking (UDI): Sterile, Permanent, and Standards-Compliant Coding
Medical device laser marking is critically important for product traceability and patient safety. Within the scope of the UDI (Unique Device Identification) system, unique identification codes are processed on medical devices. These codes are generally in DataMatrix format and contain the device’s production information. Fiber laser and UV laser technologies enable sterile, permanent, and high-contrast marking on medical device surfaces. This technical guide explains in detail medical device marking processes, UDI standards, and application methods.
Medical Device Marking Technology and the UDI System
What is UDI?
UDI (Unique Device Identification) is an international system that enables medical devices to be identified with a unique identity.
Why is marking important on medical devices?
Devices must be traceable for patient safety and product tracking.
Use of fiber laser
Fiber laser systems provide high-contrast marking on metal medical devices.
Use of UV laser
UV laser performs marking on plastic and sensitive medical components with low heat effect.
DataMatrix code marking
DataMatrix codes are generally used in UDI systems.
Sterilization compatibility
Laser marking creates permanent marks resistant to sterilization processes.
Surface contrast
High-contrast marking is important for readability.
Micro marking
Micro-scale codes can be processed on small medical devices.
Standards compliance
Marking must comply with ISO and FDA standards.
Industrial application areas
- Surgical instruments
- Implants
- Medical device components
- Laboratory equipment
