Elastic 50A Resin V1 is ideal for developing soft, flexible prototypes normally produced with silicone.

Consider Elastic 50A Resin V1 for:

Wearables, such as straps
Compressible buttons
Stretchable enclosures and casings
Compliant features for robotics
Soft tissue anatomy and medical models
Special effects props and models

Material properties may vary based on part geometry, print orientation, print settings, and temperature. Data was obtained from parts printed on a Form 2 printer with 100 µm Elastic settings, washed in a Form Wash for 20 minutes, and post-cured at 60°C for 20 minutes in a Form Cure.


Form Wash Settings


10 minutes + 10 minutes


Wash Elastic 50A Resin for 10 minutes on the build platform. Remove parts from the build platform, then wash for 10 more minutes using fresh solvent. Avoid washing Elastic 50A Resin for longer than 20 minutes, as this may degrade parts.

Form Cure Settings


20 min



60 °C


For parts printed in an engineering-focused resin (such as those in the Rigid, Tough & Durable, and Flexible & Elastic families), post-curing ensures that the parts reach their optimal mechanical properties and can function as designed. There is only one recommended post-curing time for Elastic 50A Resin.
