IIa. Disclaimer In our commitment to help minimize 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 are subjected to skin contact should meet the biocompatibility requirements stated in ISO 10993-1. Please note that Formlabs materials not categorized as biocompatible were not designed to meet these requirements. If your specific performance needs are beyond the scope of the original non-biocompatible material design, please consult Formlabs for further information on the potential use of secondary processing. Any additional modifications outside the published guidance for use must be tested by the manufacturer prior to implementation. IIb. Important Note on Material Selection Biocompatible materials should be used for applications requiring skin contact.  Formlabs Surgical Guide Resin, intended for printing endosseous implant accessories, is biocompatible for short term surface contact (ex: mucosal membrane) and may be autoclaved. If a more pliable material is used to increase comfort, such as Formlabs Tough 1500 Resin or Durable Resin, we recommend the application of biocompatible coatings (e.g., luxaprint flex coat and ComfortCoat) or adhering moleskin tape across any piece which may touch the skin.  Make sure the biocompatible coatings are also compatible with other application requirements prior to 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. Note:  Luxaprint flex coat, ComfortCoat, and EP-42HT-2Med are third party coatings not affiliated with Formlabs Inc.
