SLA Material – Flexible 80A Resin

Flexible 80A Resin For Hard Flexible Prototypes.

Flexible 80A Resin is the most stiff soft-touch material in our library of Flexible and Elastic Resins, with an 80A Shore durometer to simulate the flexibility of rubber or TPU. Balancing softness with strength, Flexible 80A Resin can withstand bending, flexing, and compression, even through repeated cycles. This material is well suited for cushioning, damping, and shock absorption.

Common Applications:

Compliant features for robotics.
Handles, grips, over molds.
Low quantity production of small parts.
Cartilage and ligament anatomy.
Special effects props and models.
Seals, gaskets, masks.
