Is PLA truly biocompatible?
A
Looking for advice. I’m looking at PLA for single-use medical prototypes because of its biodegradable properties, but I’m not sure about its suitability for biocompatibility in short-term contact with human skin or fluids. Any experience or insights into whether standard PLA grades can meet biocompatibility requirements, or would I need to source medical-grade PLA for this application?
