Formlabs Silicone 40A Resin (Form 3) - 1L is the first accessible pure silicone 3D printing material designed for the Form 3 series ecosystem. By leveraging patented PureSil Technology™, this elastomeric resin allows for the rapid production of high-performance silicone parts in-house. Consequently, engineering teams can bypass the significant lead times and high costs associated with traditional tooling, such as compression or injection moulding.
Engineering Applications for Formlabs Silicone 40A Resin (Form 3) - 1L
This material is specifically formulated for applications requiring high chemical resistance, thermal stability, and long-term durability. It is ideal for producing custom seals, gaskets, actuators, and bellows that must withstand repeated mechanical stress. Furthermore, the shore 40A durometer provides a balance of flexibility and toughness, ensuring that complex geometries maintain their structural integrity under compression.
The integration of Formlabs Silicone 40A Resin (Form 3) - 1L into your workflow simplifies the prototyping of consumer goods and industrial components. Unlike TPU or other elastomeric resins, this pure silicone material offers the authentic feel and performance of conventionally manufactured silicone. This capability is vital for functional testing where material properties must match the final production intent precisely.
To achieve optimal mechanical properties, parts must be printed on a Form 3 series printer and undergo the standard wash and post-cure process. Users should note that this resin requires the use of a Resin Tank V2.1 or higher to ensure consistent print quality and hardware longevity whilst processing the high-viscosity formulation.
