Formlabs Grey Resin V4 (Form 3) - 1L is a versatile, high-resolution material designed for general-purpose prototyping and the production of parts with intricate details. This formulation is engineered to deliver a neutral matte finish that excels at capturing fine surface features whilst maintaining excellent dimensional stability. Consequently, it is the primary choice for designers and engineers requiring aesthetic models that accurately represent the final look and feel of injection-moulded components.

Mechanical Integrity of Formlabs Grey Resin V4 (Form 3) - 1L

Furthermore, the material properties of this V4 iteration provide a robust balance of strength and surface quality. With a post-cured stiffness (Tensile Modulus) of 2.8 GPa and a Shore Hardness of 82D, the resin is sufficiently rigid for form and fit testing across various industrial applications. The Heat Deflection Temperature of 72 °C ensures that prototypes remain stable under the ambient heat generated by electronic components or low-intensity thermal testing.

Processing and Final Finish

Utilising Formlabs Grey Resin V4 (Form 3) - 1L allows for efficient post-processing to reach peak mechanical performance. After printing, parts should be washed in Isopropyl Alcohol (IPA) and post-cured at 60 °C for 30 minutes. This workflow ensures the material achieves its full 82D hardness and optimal thermal resistance. The resulting neutral grey tone is an excellent base for painting or other finishing techniques whilst remaining visually clear for margin inspections.
