SLA Material – Elastic 50 A Resin

Elastic 50 A Resin For Soft Flexible Parts.

Our softest Engineering Resin, this 50A Shore durometer material is suitable for prototyping parts normally produced with silicone. Choose Elastic Resin for parts that will bend, stretch, compress, and hold up to repeated cycles without tearing.

Common Applications:

Compliant features for robotics.
Wearables and consumer goods prototyping.
Low quantity production of small parts.
Medical models and devices.
Special effects props and models.
Compressible buttons.
