Flexible 50A Resin is a soft, translucent 3D printing elastomer with a 50A Shore durometer that is ideal for prototyping parts normally produced with softer rubbers and silicones.

Parts printed in Flexible 50A Resin will bend, stretch, compress, and hold up to repeated cycles without tearing, and spring back quickly to their original shape.

Why Choose Flexible 50A Resin?

Flexible 50A Resin is an elastomeric material with high elongation and high energy return. Parts are highly elastic, yet strong enough not to tear during printing.


Fast Springback

Bend, stretch, and compress parts that resume their normal shape afterwards.


Transparent

Create objects that are clear, providing visibility into the model.


Durable

Able to withstand rugged use for multiple cycles.


Pliable

Produce parts that look and feel like a molded silicone part.

Applications

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

Consider Flexible 50A Resin 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

Post-Processing

Washing

The foundational step in any SLA post-processing workflow is to remove any excess resin on the surface of the parts through an alcohol or ether wash.

Curing

Post-curing Engineering and Specialty Resins is essential for parts to achieve their full strength and functionality. This step completes the chemical reaction initiated during printing, transforming the part from its green state into a fully finished component.
