3Dresyn EP4 RTD90, Rigid Tough Photopolymer 3D Resin

It is ideal for emergency printing of heat resistant respirator fans. It is supplied as samples with no profit to customers who can justify their lack of resources in order to support emergency printing of parts for hospital use.

Designed for use in vat photopolymerization systems (SLA, DLP and LCD) within controlled professional environments for emergency printing of rigid, tough and heat resistant parts for hospital use.

Final heat resistance, rigidity, impact 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.
