Introducing Flexible 50A Resin V2, the premier soft, translucent elastomeric material engineered for high-performance 3D printing. This resin is specifically formulated to replicate the properties of soft rubbers and silicones, featuring a robust 50A Shore durometer. Ideal for engineers and designers, it produces parts that offer exceptional flexibility, durability, and rapid springback, making it perfect for demanding cycles of bending and compression.
The Ultimate Flexible 3D Printing Material
Exceptional Elasticity
Parts manufactured with this advanced elastomer are designed to withstand significant dynamic stress. The material excels in applications requiring continuous deformation, such as stretching, compression, and repeated flexing, all while maintaining structural integrity without tearing. The unique V2 formulation ensures printed components quickly return to their original geometry, a crucial factor for functional prototypes that require high elongation and substantial energy return.
Durability and Feel
Beyond its impressive mechanical resilience, this resin provides an authentic, pliable tactile experience, closely mimicking the feel and function of molded silicone parts. The resulting models are durable and capable of prolonged, rugged use across multiple functional cycles, giving designers confidence in their prototype’s real-world viability. The translucent finish also provides valuable visibility into complex internal models.
Professional Prototyping and Production Applications
Versatile Functionality
Flexible 50A Resin V2 is the optimal choice for developing flexible prototypes that traditionally require soft silicone materials. Its specific mechanical profile caters to a wide array of functional requirements across various industries. Consider this material for:
- Wearables, including watch straps and comfortable fittings.
- Compressible interface components like buttons and gaskets.
- Stretchable protective casings and enclosures.
- Compliant features vital for sophisticated robotics.
- High-fidelity soft tissue anatomy models for medical training.
- Detailed special effects props and models.

Product Name Update
As part of the SLA resin line unification, Formlabs is introducing a new naming system. Starting June 9, 2026, the material names have been updated:
- Elastic 50A Resin V2 → Flexible 50A Resin
- BioMed Elastic 50A → BioMed Flex 50A Resin
These changes affect the product name only. The formulation, performance characteristics, and printer compatibility remain unchanged.
Labeling Note: during the transition period, customers may receive cartridges with legacy labels (Elastic 50A or BioMed Elastic). This is a purely cosmetic difference and does not affect material performance or compatibility with PreForm.
