IIa. Disclaimer: In our commitment to minimizing the impact of personal protective equipment shortages during the COVID-19 pandemic, Formlabs is dedicated to providing safe and effective solutions. Any 3D printed appliances that come into contact with skin must meet the biocompatibility requirements stated in ISO 10993-1. Note that Formlabs materials not categorized as biocompatible were not designed to meet these requirements. If your specific performance needs go beyond the original non-biocompatible material design, please consult Formlabs for further information on using secondary processing. Any additional modifications outside published guidance must be tested by the manufacturer before implementation. IIb. Important Note on Material Selection: Biocompatible materials should be used for applications involving skin contact. Formlabs Surgical Guide Resin is biocompatible for short-term surface contact and may be autoclaved. If a more pliable material like Tough 1500 Resin or Durable Resin is used to increase comfort, we recommend applying biocompatible coatings such as Luxaprint Flex Coat and ComfortCoat or adhering moleskin tape across any piece that comes into contact with the skin. Make sure biocompatible coatings are also compatible with other application requirements before use. An example is EP42HT-2Med, a USP Class VI coating that is solvent resistant and compatible with multiple sterilization cycles. Follow manufacturer instructions to ensure uniformly coated surfaces for optimal performance.
