Tough 2000 Resin for Rugged Prototyping

Tough 2000 Resin is the strongest and stiffest material in our functional family of Tough and Durable Resins. Choose Tough 2000 Resin for prototyping strong and sturdy parts that should not bend easily.

Tough 2000 Resin is ideal for:

  • Strong and stiff prototypes
  • Jigs and fixtures requiring minimal deflection
  • Simulating the strength and stiffness of ABS

Technical data:

Due to its high strength and modulus, Tough 2000 Resin can handle higher stress and will hold its shape better under load compared to Tough 1500 or Durable Resins. When pushed to its stress limit, Tough 2000 parts will bend significantly before ultimately breaking.


Tough 2000 Resin is a reformulation of Formlabs' popular Tough Resin, offering more advanced mechanical properties and a new dark grey look. Compared to Tough Resin, this material reformulation brings:

  • Reduced brittle failures: Increased elongation by more than 100%.
  • Improved strength and stiffness: Increased flexural strength and flexural modulus by roughly 15%.
  • Better performance at elevated temperatures: Increased heat deflection temperature by roughly 25%.
  • Professional-looking parts: New grey color.

With this reformulation, Formlabs' simultaneously improved elongation, strength, and stiffness, which are typically competing mechanical properties.

Note that Tough 2000 Resin requires Formlabs specialty resin tanks, Form 2 LT Tank or Form 3 Tank v2.
