Formlabs Tough 1000 Resin Form 4, 5L

Formlabs Tough 1000 Resin Form 4, 5L

Discover the industrial-grade capabilities of the Formlabs Tough 1000 Resin Form 4, 5L, a material engineered to withstand the rigors of real-world application. Designed specifically for the high-speed Form 4 ecosystem, this resin offers mechanical properties comparable to High-Density Polyethylene (HDPE), making it the premier choice for engineers needing parts that can bend, flex, and resist heavy impact. Please note that this high-volume 5-liter container is designed for continuous production and requires the Formlabs Resin Pump for operation. Items with longer delivery times are typically made to order to ensure maximum shelf-life freshness.

Why Choose Tough 1000 Resin?

Stiffness and Ductility Combined

The Formlabs Tough 1000 Resin Form 4, 5L is a powerhouse material that balances strength with flexibility. It is characterized by its ability to absorb energy without shattering, boasting a ductility and impact resistance that rivals standard thermoplastics like HDPE. This makes it an exceptional solution for prototyping and end-use parts that must endure significant physical stress. Whether you are creating functional prototypes or manufacturing aids, this resin ensures your components remain intact under pressure.

Superior Impact Resistance

What sets this material apart is its impressive elongation at break of 180% and a Gardner impact strength of 128 in-lb. These metrics surpass those of traditional HDPE, allowing for the creation of durable enclosures and protective housings that can survive drops and collisions. Unlike brittle materials that snap, Tough 1000 yields and recovers, providing the resilience needed for demanding environments.

Performance and Reliability

Engineered for Cyclic Loading

Functional parts often face repetitive stress, and Formlabs Tough 1000 Resin Form 4, 5L is built to handle exactly that. With a work of fracture of 3,200 J/m² and the ability to withstand over 100,000 cycles in Ross flex fatigue testing, this material is ideal for living hinges, snap-fits, and compliant mechanisms. It allows engineers to print jigs and fixtures that maintain their integrity even after thousands of uses on the factory floor.

Smooth Low-Friction Finish

Beyond its mechanical toughness, the resin cures to a professional matte dark grey finish that is smooth to the touch. It offers low-friction surface properties comparable to Delrin (POM), making it suitable for moving assemblies where parts slide against one another. This lubricity reduces wear and tear, preventing abrasion and scratching in mechanical systems like gears, ball joints, and sliding fixtures.

Versatile Applications

From Prototyping to Production

The advanced formulation of Tough 1000 Resin leverages the speed and precision of the Form 4 Series printers. It offers significantly higher fracture toughness and improved resistance to environmental factors such as heat, creep, and aging compared to standard Durable Resin. This stability ensures that parts resist warping and maintain their dimensional accuracy over time.

Consider using this material for:

• Functional prototypes requiring the stiffness and feel of HDPE.
• Rugged jigs and fixtures for long-term manufacturing use.
• Compliant mechanisms and parts subject to repeated flexing.
• Wear-resistant, low-friction assemblies.

Post-Processing Recommendations

Washing and Cleaning

To achieve the best results with Formlabs Tough 1000 Resin Form 4, 5L, proper post-processing is crucial. The first step involves removing uncured resin from the surface using an isopropyl alcohol (IPA) or ether wash. Formlabs recommends allowing the washed parts to air dry for at least 30 minutes before handling to ensure a pristine surface finish.

Curing for Maximum Strength

Like all engineering resins, post-curing is essential to unlock the material's full mechanical potential. This process completes the polymerization reaction, transforming the "green" part into a fully functional component with maximum strength and stability. Utilizing a Form Cure unit ensures uniform light and heat exposure for consistent results.
