Formlabs Silicone 40A Resin

Silicone 40A Resin, the first accessible 100% silicone 3D printing resin. Eliminate molding and labor-intensive casting processes: Silicone 40A Resin uses Formlabs’ patent-pending Pure Silicone Technology™  to 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 can 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 that are not possible with traditional methods.

Disclaimer: Formlabs are currently awaiting TSCA registration. Until Formlabs obtains this registration, Silicone 40A Resin can only be used for research and development (R&D) purposes. Formlabs expects to receive TSCA registration in late 2023. Once Formlabs receive the registration, this resin can be used for commercial, R&D, and any other suitable applications.
