Formlabs Grey Pro Resin (Form 3) - 1L is a high-precision engineering material designed for versatile prototyping and functional testing under moderate stress. This resin offers a unique balance of high elongation and low creep, making it suitable for parts that require dimensional stability over time. Consequently, it is an ideal choice for engineers developing conceptual models, functional assemblies, and injection-moulded prototypes that must maintain their form during repeated handling.

Mechanical Performance of Formlabs Grey Pro Resin (Form 3) - 1L

Furthermore, the material properties of this resin ensure reliable performance for parts subjected to thermal and mechanical loads. With a post-cured Heat Deflection Temperature of 78 °C at 0.45 MPa and a Shore Hardness of 80D, the resin provides the structural integrity required for rigorous laboratory testing. The 2.6 GPa Tensile Modulus indicates a high level of stiffness, whilst the 13% elongation at break allows for a degree of flexibility that prevents brittle failure in functional components.

Application and Post-Processing Requirements

Utilising Formlabs Grey Pro Resin (Form 3) - 1L requires adherence to specific post-processing protocols to reach its full mechanical potential. Parts must be washed in Isopropyl Alcohol (IPA) for 15 minutes and post-cured at 80 °C for 15 minutes. This thermal treatment ensures the polymer matrix is fully cross-linked, achieving the specified stiffness and thermal resistance required for professional engineering applications.
