Product Overview

Tough 1000 Resin

Exceptional Ductility.

Long-Term Durability

Tough 1000 Resin is a ductile, impact-resistant material with the strength, stiffness, and toughness of high-density polyethylene (HDPE) — engineered for parts that must endure repeated stress, bending, and compression without cracking. Designed for long-term wear and fatigue resistance, it’s ideal for functional components that need to flex and perform under demanding conditions.

Built for Utility and Endurance

Tough 1000 Resin excels in applications where durability, flexibility, and reliability are essential:

Hinges, clips, and snap-fit joints

Wear-resistant mechanical parts

Flexible prototypes and enclosures

Components exposed to repetitive motion or load cycling

Outstanding Mechanical Performance

Engineered for extreme toughness and fatigue resistance, Tough 1000 Resin delivers:

  • 180% elongation at break (EAB) —

  • 128 in-lb Gardner impact strength —

  • Work of fracture:

  • Ross flex fatigue:

  • Matte, dark gray finish —

Advanced Resin Formulation

Developed for the Form 4 Series printers, Tough 1000 Resin takes advantage of next-generation resin technology to achieve:

5× higher fracture toughness

2× higher elongation at break

Enhanced temperature, creep, and aging resistance

Improved surface quality and finish straight off the printer

Designed for Real-World Use

Parts printed in Tough 1000 Resin can withstand repeated flexing and compression while maintaining shape and mechanical performance. Its balanced combination of ductility and strength makes it the perfect choice for functional prototypes and production-grade flexible parts.
