Why Micron-Level Tolerances Are Non-Negotiable in Medical Devices

Medical devices demand precision that transcends conventional engineering standards. A single micron deviation in an implantable component can compromise biocompatibility, while a 0.001-inch tolerance error in a surgical instrument may cause catastrophic failure during critical procedures. Regulatory frameworks like FDA 21 CFR Part 820 and ISO 13485 mandate strict dimensional control, but true excellence requires going beyond compliance to prevent failures before they occur.
