Formlabs Tough 1000 Resin for Form 4, 5 L

Unlock the true potential of industrial 3D printing with the Formlabs Tough 1000 Resin Form 4, 5L. Engineered specifically for the high-speed Form 4 ecosystem, this material delivers mechanical performance that rivals high-density polyethylene (HDPE). Whether you are prototyping functional assemblies or manufacturing end-use parts, this 5-litre cartridge provides the volume required for continuous production, offering exceptional impact resistance and ductility for your most demanding engineering challenges. Important note: this large-format cartridge requires the use of a Resin Pump to operate.

Why Choose Formlabs Tough 1000 Resin?

Engineering-Grade Performance

This material stands out as a ductile, impact-resistant solution capable of mimicking the strength and rigidity of standard industrial plastics. With an elongation at break of 180%, the Formlabs Tough 1000 Resin Form 4, 5L surpasses HDPE, making it the ideal choice for components that must withstand bending, compression, or deformation without cracking. It represents a significant leap in materials science, offering five times greater fracture toughness and improved environmental stability compared to previous Durable Resin formulations.

Superior Durability and Fatigue Resistance

Engineers rely on this resin for parts subjected to repeated stress. Capable of withstanding over 100,000 cycles without failure, it is ideal for printing functional hinges, springs, and flexible mechanisms. The material boasts a fracture energy of 3,200 J/m², ensuring that your jigs, fixtures, and housings remain intact even under significant physical stress in demanding factory environments.

Low-Friction Surface Finish

Beyond mechanical strength, parts printed with this resin feature a professional matte dark grey finish that is smooth to the touch. It offers low-friction properties comparable to Delrin (POM), enabling the creation of wear-resistant assemblies where surfaces slide against one another. This makes it excellent for ball joints, gears, and moving mechanical assemblies that demand longevity and minimal abrasion.

Key Applications for Tough 1000 Resin

Versatile Manufacturing Solutions

The unique properties of this photopolymer make it suitable for a wide range of engineering tasks. It is specifically designed for parts requiring the rigidity of HDPE, impact-resistant tooling that survives prolonged workshop use, and surfaces that do not degrade. From prototyping snap-fits to creating robust end-use housings, this material delivers consistent, high-quality results.

Post-Processing Recommendations

How to Achieve Maximum Strength

To ensure your prints reach their full mechanical potential, proper post-processing is essential. After printing, parts should be washed in isopropyl alcohol or ether to remove excess resin. Formlabs recommends air-drying parts for at least 30 minutes after washing to achieve the best surface finish. Finally, post-curing is critical to transition the part from a "green" state to a fully finished component with maximum strength and stability.
