Formlabs Black Resin V5 (Form 4) is a high-precision General Purpose Resin designed for Sydney additive manufacturing labs requiring rich, opaque parts and exceptional surface finish. This formulation is optimised for the Form 4 ecosystem, printing up to three times faster than previous versions whilst capturing fine features with a smooth matte finish that minimises light reflection. It is the definitive choice for Formlabs AU users developing enclosures, housings, and high-contrast prototypes.
Expert Tip: To achieve the maximum tensile modulus of 2700 MPa and an HDT of 69°C, parts must be post-cured for 15 minutes at 60°C. This ensures the material reaches its full mechanical potential for functional testing.
Key Technical Applications
- Enclosures and Housings: The deep black, matte finish is ideal for internal electronics components and light-sensitive enclosures.
- Rapid Prototyping: High dimensional accuracy allows for iterative form and fit testing of complex assemblies.
- Manufacturing Aids: Provides sufficient stiffness and durability for the production of shop-floor jigs and fixtures.
Technical Note: Black Resin V5 exhibits a 4.9% weight gain when exposed to Acetone over a 24-hour period. Avoid prolonged immersion in aggressive solvents to preserve the matte surface quality and part integrity.
