100% Pure Silicone for High-Speed Functional Elastomers
Silicone 40A Resin is the first accessible material to offer the authentic chemical and thermal performance of silicone in a 3D printable format. With a Shore 40A Durometer, it provides the ideal balance of softness and durability. Unlike "silicone-like" resins, this is a true elastomer that retains its mechanical integrity across millions of flex cycles and extreme temperature shifts, making it a reliable choice for industrial gaskets, consumer wearables, and medical models.
Key Features
-
100% Pure Silicone Chemistry: Offer superior thermal stability and chemical resistance compared to traditional photopolymer elastomers.
-
Unmatched Resilience: Features a low compression set and high rebound, ensuring seals and gaskets maintain their shape under prolonged pressure.
-
Exceptional Fatigue Resistance: Validated for over 1 million flex cycles, providing the long-term durability required for dynamic mechanical assemblies.
-
Professional Surface Finish: Delivers smooth, non-tacky surfaces that feel like traditionally molded silicone, with high dimensional accuracy for tight-fitting seals.
Ideal Applications
-
Custom Gaskets & Seals: Chemical-resistant, high-temperature seals for industrial equipment.
-
Consumer Wearables: Soft-touch straps, ear tips, and skin-contacting ergonomic grips.
-
Medical Training Models: Realistic, soft-tissue phantoms for surgical simulation and planning.
-
Robotics & Grippers: High-friction, flexible end-of arm tooling for delicate object handling.
-
Vibration Dampers: Custom-shaped isolators for sensitive electronic assemblies.
FAQ
How Does This Differ from the Form 3 Version?
The Form 4 formulation is specifically tuned for the LFD light engine, providing significantly faster print times and sharper feature definition while maintaining the same high-performance silicone properties.
Is it Biocompatible?
While Silicone 40A is a pure silicone, this specific version is intended for industrial and general prototyping. For medical applications requiring certified biocompatibility, please refer to the BioMed material library.
Do I Need a Special Build Platform?
The Build Platform 2 for Form 4 is highly recommended. Because silicone parts are soft and flexible, the Flex-Release technology allows you to remove parts without the risk of tearing them with a scraper.
