3Dresyn EP3 TFD30 Black, Tough, Flexible & Foldable for "Emergency Printing" of flexible respirator masks

3Dresyn EP3 TFD30 Black is a tough, flexible and foldable photopolymer designed for emergency printing of flexible respirator masks.

This material is supplied as samples with no profit to customers who can justify their lack of resources. It is intended to support emergency printing of flexible parts for hospital use in demanding pandemic scenarios.

Designed for use in vat photopolymerization systems (SLA, DLP and LCD) within controlled professional environments for emergency printing of flexible, foldable and durable parts for hospital use.

Final mask fit, flexibility, temperature resistance, printability and suitability for hospital-use applications depend on printer type, exposure settings, part geometry, processing conditions and post-curing workflow, and must be validated by the user according to the intended application.

This material is supplied as a professional manufacturing material and is not marketed as a finished medical device. Final part performance and suitability must be validated by the user according to the intended application.
