Formlabs Durable Resin Form 4, 5L

Unlock the potential of flexible, wear-resistant printing with Formlabs Durable Resin Form 4, 5L. Designed specifically for the high-speed Form 4 generation of 3D printers, this material is the perfect solution for engineers and designers seeking parts that mimic the mechanical properties of Polyethylene (PE). Whether you are prototyping consumer packaging or creating low-friction mechanical assemblies, this large-format container ensures continuous production for your most demanding projects, providing a reliable workflow for industrial applications.

Key Features and Benefits

Impact Resistance and Flexibility

Durable Resin V2 stands out as a pliable and robust material capable of absorbing energy without shattering. It is engineered to produce squeezable parts and components that require high impact resistance. With a surface finish that offers low friction—comparable to Delrin® (POM)—it is exceptionally well-suited for sliding assemblies and ball joints where smooth movement is critical. To utilize this high-capacity 5L container effectively, a Resin Pump is required, streamlining your workflow for consistent, industrial-grade output.

Ideal for Functional Prototypes

When your application demands longevity and resilience, Formlabs Durable Resin Form 4, 5L delivers exceptional results. It is the optimal choice for fabricating jigs and fixtures that undergo significant impacts on the manufacturing floor, as well as squeezable prototypes that need to return to their original shape. While this resin is highly capable, users looking for enhanced temperature resistance, creep resistance, and 5x higher fracture toughness might also consider Tough 1000 Resin. Please note that direct sales of Durable Resin V2.1 for Form 4 are scheduled to cease in May 2026, so evaluating Tough 1000 for future-proofing your production line is recommended.
