Overview

Silicone 40A Resin is the first accessible 100% silicone 3D printing material, using Formlabs' patent-pending Pure Silicone Technology™. Eliminate molding and labor-intensive casting processes and 3D print pure silicone parts in-house in a matter of hours. With this 40A Shore durometer material, you can fabricate soft, pliable, and durable parts with a 230% elongation at break and a 12 kN/m tear strength that withstand repeated cycles of stretching, flexing, and compression. Combine the high performance of silicone and the design freedom of 3D printing to create highly functional silicone parts with excellent chemical and thermal resistance (-25°C to 125°C), fine features as small as 0.3 mm, and complex geometries not possible with traditional methods.

Why Choose Silicone 40A Resin

Silicone 40A Resin is a pure silicone material without added monomer or acrylate, combining the superior material properties of cast silicone with the benefits of 3D printing. Outstanding elastomeric performance allows you to produce soft, pliable, and durable parts with a 230% elongation at break, 12 kN/m tear strength, and thermal stability from -25°C to 125°C. It offers newfound design freedom to create customized silicone parts with isotropic properties, fine features as small as 0.3 mm, and complex geometries that are not possible with casting or molding. Eliminating tooling and labor-intensive casting processes enables cost-effective rapid prototyping and low-volume manufacturing in-house in a matter of hours. Recommended applications include seals and gaskets, wearables, customized medical devices, validation units, tooling, and small batches of silicone parts.
