Formlabs Durable Resin Form 4, 5L

Formlabs Durable Resin Form 4, 5L

Unlock the potential of your additive manufacturing workflow with the high-capacity Formlabs Durable Resin Form 4, 5L. This specialized photopolymer is engineered for professionals who demand resilience and flexibility in their 3D printed parts. Designed specifically for the latest generation of Formlabs printers, this 5-liter container ensures you have ample material for continuous production runs, maximizing efficiency. Whether you are prototyping squeezable components or creating low-friction assemblies, this material offers the distinct mechanical properties needed for functional engineering applications. Please note that this large-format container requires a Resin Pump for proper operation within the Form 4 ecosystem.

Advanced Properties of Formlabs Durable Resin Form 4, 5L

Pliable and Robust Performance

The Durable Resin V2 formulation stands out in the market because it effectively combines impact resistance with a smooth, lubricious surface finish. It behaves remarkably like Polyethylene (PE) regarding stiffness and strength, making it an ideal choice for parts that need to flex without breaking. Furthermore, its coefficient of friction rivals that of Delrin® (POM), allowing for the creation of sliding mechanisms and moving parts that operate smoothly without excessive wear. This unique balance makes Formlabs Durable Resin Form 4, 5L a top contender for producing long-lasting, functional parts.

Versatile Engineering Applications

This material is the go-to solution for engineers working on squeezable prototypes, such as packaging bottles or flexible grips that require a tactile, yielding feel. It also excels in the production of manufacturing aids, specifically jigs and fixtures that are subjected to significant impacts on the factory floor. By using this resin, you can produce functional parts that withstand the rigors of real-world testing and daily use, ensuring your prototypes match the performance of final injection-molded products.

Strategic Material Selection

While Durable Resin is excellent for specific needs, users of the Form 4 Series should also consider the broader material ecosystem. For applications requiring significantly higher fracture toughness (up to 5x) and improved resistance to temperature and creep, Formlabs recommends exploring Tough 1000 Resin. Additionally, please be aware that Durable Resin V2.1 for Form 4 generation printers is scheduled to be discontinued for direct purchase starting May 31, 2026. For long-term production planning, transitioning to Tough 1000 Resin is advised as a superior alternative for many structural applications.
