Laser Processing for Medical Devices
Medical device manufacturing demands the ultimate in precision, cleanliness, and regulatory compliance. Laser cutting and processing enables micro-scale features (<100μm) on biocompatible materials like Nitinol, cobalt-chrome, and medical-grade titanium — capabilities that no other cutting technology can match.
Quick Answer
Medical device laser cutting uses pulsed fiber or ultrashort-pulse (USP) lasers with typical power of 50W–500W (not kW-class). Feature sizes down to 20μm are achievable. Key requirements: FDA QMSR process validation (IQ/OQ/PQ) per ISO 13485:2016, and biocompatible surface finishes with Ra < 0.4μm after post-processing.
Medical Device Laser Applications
| Application | Material | Feature Size | Laser Type | Volume |
|---|---|---|---|---|
| Coronary stents | 316LVM, CoCr, NiTi | 60–100μm struts | Pulsed fiber / USP | Millions/year |
| Orthopedic implants | Ti-6Al-4V ELI, CoCr | 0.5–3mm features | CW/pulsed fiber | 100K+/year |
| Surgical instruments | 17-4PH, 440C SS | 0.2–2mm | CW fiber | Varies |
| Hypodermic needles | 304 SS tube | 0.1–0.5mm | Pulsed fiber | Billions/year |
| Catheters/guidewires | Nitinol, SS hypo tube | 50–200μm patterns | USP / pulsed fiber | Millions/year |
Key Requirements
Precision
