White paper for production managers in medical technology: reliable UDI marking, resilient processes, fewer rejects
UDI markings on surgical steels must remain clearly legible and corrosion-free even after hundreds of cleaning and sterilization cycles. The white paper shows how you can reliably integrate black marking with ultrashort pulse lasers into series production and thus ensure your traceability in the long term. Technical background, ideal parameter windows, and proven post-treatment concepts help you to design sturdy marking processes.
- Implement requirements from UDI and everyday clinical practice into specific process criteria
- Evaluate suitable steels, pre-treatments, and their influence on corrosion and acid resistance
- Define laser parameters (pulse energy, scan speed, focus position) for high-contrast, permanent black markings
- Understand the role of LIPSS nanostructures for readability, contrast, and viewing angle dependency
- Select passivation and cleaning strategies that increase corrosion protection without weakening the marking
