Frequently Asked Technical Questions
Will laser marking remove the passive corrosion resistance of medical stainless steel?
No. For medical devices and surgical instruments, we utilize thermal laser annealing. Rather than vaporizing the base material, the laser beam induces controlled localized oxidation beneath the passive chromium-oxide layer, resulting in a dark, high-contrast mark that retains corrosion resistance and survives over 1,000 autoclave steam sterilization cycles.
Can Lumicision produce serialized barcodes, QR codes, and 2D DataMatrix codes?
Yes. Our high-speed galvo scan heads support variable automated serialization, lot codes, date codes, GS1 DataMatrix (FDA UDI compliant), and MIL-STD-130 UID defense barcodes with automated grading to ISO/IEC 15415 and AIM DPM verification standards.
What is the difference between Fiber MOPA and UV cold laser marking?
Fiber MOPA lasers operate at 1064nm with adjustable pulse widths, making them ideal for high-speed deep etching and color-marking on metals. UV cold lasers operate at 355nm, delivering high photon energy that breaks chemical bonds without thermal heat, creating crisp, dark marks on sensitive plastics (PEEK, Delrin, silicone) and glass without surface burning.
What is the turnaround time for laser marking production batches?
Because laser marking requires minimal setup fixturing and zero mechanical tooling, small prototype runs can be completed within 24 to 48 hours, and production runs of thousands of serialized parts can be handled with high-speed automated indexing.
Engineer-Reviewed Fast-Track RFQ
Unlike automated black-box algorithms that reject complex tolerances or overcharge for simple bends, every file uploaded to Lumicision is reviewed by a senior fabrication engineer—with a 24 to 48-hour guaranteed quote response time.
