Introducing 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. 

Silicone 40A Resin parts, with 40A Shore durometer, 230% elongation at break, and 12 kN/m tear strength, are ideal for applications requiring pliability and durability even through repeated stretching, flexing, or compression. Parts made with Silicone 40A Resin have a rebound resilience of 34%, excellent chemical and thermal resistance (-25°C to 125°C), and can have fine features as small as 0.3 mm and complex shapes that are challenging to achieve with traditional manufacturing methods.
