Meeting the extremely tight tolerances of micro-sized components and features for critical medical devices requires absolute precision. It also requires having the experience to know what you don’t know, so you can confidently try new approaches to meet the highly technical needs of creating parts that generally weigh less than one-tenth of a milligram and are 10 times smaller than a grain of table salt. That’s because, as far as advanced micro-manufacturing technology has come, it still has ways to go.
