Formlabs | Silicone 40A Resin

Silicone 40A Resin is the first accessible 100% silicone 3D printing material, powered by Formlabs’ patent-pending Pure Silicone Technology™. It eliminates the need for molding or labor-intensive casting, enabling fast in-house production of pure silicone parts in just hours.

With a 40A Shore durometer, 230% elongation at break, and 12 kN/m tear strength, this material produces soft, pliable, and durable parts that withstand repeated stretching, flexing, and compression.

Silicone 40A Resin combines the high performance of silicone with the design freedom of 3D printing, allowing the creation of highly functional parts with excellent chemical and thermal resistance (–25 °C to 125 °C), fine features down to 0.3 mm, and complex geometries not achievable with traditional methods.
