Flexible 80A Resin is a translucent elastomer with an 80A Shore durometer, offering a stiff yet soft-touch feel. It’s ideal for prototyping rubber-like parts with the flexibility of harder rubber or TPU.

Printed parts can endure bending, flexing, and compression, maintaining performance even after repeated cycles.

IMPORTANT: 5 L Container Requires a Resin Pump (Form 4)(Form 3) to work.

Experience the Benefits

Durable for repeated use

It withstands bending, compression and flex cycles without cracking, making it ideal for functional prototypes and flexible end-use parts.

Clear, translucent finish

Produces semi-transparent parts, enabling visibility into internal features or fluid channels in prototypes.

Rubber-like flexibility with strength

With a Shore hardness of approximately 80A, this resin behaves like harder rubber or TPU, retaining toughness for repeated movement.

Ideal for soft-touch and overmolded components

Great for grips, handles, gaskets, cushions, shock-absorbing parts, and other flexible elements that require solid mechanical performance.

frequently asked questions

What is Flexible 80A Resin used for?

It’s designed for creating flexible, rubber-like parts such as grips, seals, gaskets, cushions, and soft-touch components.

How flexible is Flexible 80A Resin?

With a Shore hardness of 80A, it feels similar to hard rubber or TPU — flexible yet strong enough to maintain its shape under load.

How durable is Flexible 80A Resin?

Flexible 80A Resin withstands repeated bending, compression, and flexing without cracking, making it suitable for functional parts.

Can Flexible 80A Resin be used for end-use parts?

Yes — it’s great for both prototypes and low-volume production parts that require flexibility and impact resistance.

What post-processing is required for Flexible 80A Resin?

After printing, parts should be washed in IPA and post-cured under UV light at 60 °C for 10 minutes for optimal strength and flexibility.
