TRUMPF UDI-compliant laser marking of medical devices

All UK medical device manufacturers wishing to trade with the US must ensure their products carry a bar-coded Unique Device Identifier (UDI) so that they can be tracked through the entire supply chain. To meet this need, TRUMPF has developed a laser and software module for UDI marking, specially designed to create corrosion-resistant marks on highly reflective materials using ultra-short pulsed lasers.

The new TruMicro Mark 2000 offers an ultra-short pulsed laser and high pulse energies of up to 20 microjoules. It produces completely corrosion-resistant marks that maintain their high contrast appearance even after repeated cleaning and sterilisation.

The pulses emitted by the TruMicro Mark 2000 are short enough to enable cold material processing.  This means the time taken to absorb the laser energy is shorter than the time required to heat up the surrounding material, so the marking of the material is completed before thermal processes can take effect.
