3Dresyn EP2 TFD80, Tough & Foldable for "Emergency Printing" of semi flexible parts: respirator masks, etc..

3Dresyn EP2 TFD80 is a tough and foldable photopolymer designed for emergency printing of respirator masks and related hospital-use parts.

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 and semi rigid 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, semi rigid and durable parts for hospital use.

Final mask fit, flexibility, impact resistance, 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.

This technical datasheet should be used together with the relevant processing, calibration, safety and workflow documentation available in the 3Dresyns® Resources section.
