▶ Why choose Elastic Resin 50A V2?
Elastic 50A Resin V2 is a soft, translucent elastomer with a Shore hardness of 50A, ideal for prototyping parts typically made with softer rubbers and silicones.
Parts printed with Elastic 50A Resin can be bent, stretched, compressed, and can withstand repeated cycles without tearing, and quickly return to their original shape.

Quick Rebound
Bend, stretch, and compress parts, which then return to their normal shape.
Transparent
Create clear objects, making models visible.
Durable
Withstands rigorous use over many cycles.
Flexible
Produces parts that look and feel like molded silicone parts.

Consider Elastic 50A Resin V2 for:
Wearables, such as watch straps
Compressible buttons
Stretchable enclosures and housings
Robotic compliance features
Soft tissue anatomy and medical models
Special effects props and models

▶ Why choose Flexible Resin 80A?
Flexible 80A Resin V2 is a 3D printing elastomer with high rebound, and its appearance, feel, and function are comparable to 80A cast polyurethane, TPU, and hard rubber.
Parts printed with Flexible 80A Resin V2 not only have rebound properties but also withstand repeated bending, stretching, and compression. It can be used to create tear-resistant functional prototypes and end-use parts, protect sensitive components with soft inserts and fixtures, or design delicate pads and grips with non-tacky surfaces and a matte black finish.
Flexible 80A Resin V2 features a new formulation that fully leverages the technical advantages of Form 4 series printers, with a 2x increase in tear strength, a 2x increase in elongation at break, and a 4x increase in rebound performance compared to its previous generation, while also significantly improving surface texture and aging resistance.

Elastomer
Utilize parts that are flexible and slowly return to their original shape.
Soft and Tough
Parts do not crack during repeated stretch and compression cycles.
Transparent
Create clear objects, making models visible.
Durable
Supports user testing, providing a prototype-like look and feel for testing.

Consider Flexible 80A Resin for:
Handles, grips, and overmolds
Seals, gaskets, and masks
Cushioning, damping, and shock absorption
Anatomical structures of cartilage, tendons, and ligaments
