100% Pure Silicone for Functional Elastomeric Parts
Silicone 40A Resin combines the excellent chemical and thermal resistance of silicone with the design freedom of 3D printing. With a Shore 40A Durometer, it is soft, flexible, and resilient, making it ideal for parts that must withstand repeated stretching, flexing, or compression. Unlike other flexible resins that mimic silicone, this is a pure elastomer that maintains its mechanical properties over a wide temperature range and across millions of flex cycles.
Key Features
-
Pure Silicone Properties: Offers superior thermal stability and excellent chemical resistance compared to traditional photopolymer elastomers.
-
Exceptional Resilience: Features high rebound and a low compression set, ensuring parts return to their original shape even after prolonged loading or thousands of cycles.
-
High-Cycle Durability: Tested for over 1 million flex cycles without cracking or tearing, making it suitable for high-wear industrial and consumer applications.
Ideal Applications
-
Industrial Gaskets & Seals: Custom-fit, chemical-resistant seals for machinery and fluid systems.
-
Consumer Wearables: Soft-touch straps, ear tips, and ergonomic grips.
-
Medical Models: Realistic, flexible anatomical models for surgical simulation.
-
Manufacturing Tooling: Soft-jaw inserts, vibration dampers, and protective masking for finishing processes.
FAQ
How Does this Differ From Elastic 50A or Flexible 80A?
Silicone 40A is a 100% pure silicone elastomer. While Elastic 50A and Flexible 80A are acrylic-based resins that mimic rubber, Silicone 40A provides the superior thermal, chemical, and long-term durability that only pure silicone can offer.
Can I Use This on the Form 4?
Currently, this specific 1L cartridge and formulation are optimized for the Form 3/3L series.
Does it Require a Special Build Platform?
No, but the Build Platform 2 is highly recommended. It allows you to easily remove these soft, flexible parts without using metal scrapers that could tear the material.
