Formlabs Tough 1000 Resin V1 is the most ductile and impact-resistant material in the Tough Resin family, engineered for parts that need to bend, flex, and endure repeated stress without cracking. Comparable to high-density polyethylene (HDPE), this resin offers exceptional wear and fatigue resistance, making it perfect for functional prototypes, compliant mechanisms, and long-lasting factory components.
With 180% elongation at break, 14.5 J Gardner impact strength, and a work of fracture of 3,200 J/m², Tough 1000 Resin V1 delivers unmatched durability for demanding applications. Its matte dark gray finish ensures smooth, low-friction surfaces ideal for moving assemblies like hinges, gears, and snap-fit joints. Leveraging Form 4 Series technology, this resin provides 5× higher fracture toughness and 2× greater elongation than Durable Resin, plus improved resistance to temperature, creep, and aging.
