Formlabs is making their Tough resin even tougher – with a reformation  – offering Tough 2000 as the more advanced 3D printing material.

Formlabs and EAC will continue to sell the Tough resin until it is sold out – then it will be replaced with Tough 2000. If you’ve been using Tough resin – it will be available through the end of 2020.

You can use the Tough 2000 resin on Formlabs desktop stereolithography (SLA) 3D printers – specifically on the Form 3 and Form 2

Tough 2000 vs Tough

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.

Tough 2000 Resin is the strongest and stiffest material in the functional family of Tough and Durable Resins, with “2000” representing the material’s tensile modulus. The resin is improved elongation, strength, and stiffness, which are typically competing mechanical properties.

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.

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

Other Tough and Durable Resins

This video clip shows a stress test between the Tough 2000, Tough 1500, and Durable Formlabs resins.

Tough 1500 Resin is the most resilient material and is ideal for: prototypes that repeatedly bend and quickly return to shape; jigs and fixtures requiring repeated deflection; and simulating the strength and stiffness of polypropylene (PP).

Durable Resin is the most pliable, impact resistant, and lubricious material and is ideal for: squeezable prototypes and low friction assemblies; non-degrading surfaces as a result of repeated wear; jigs and fixtures that will experience significant impacts; and simulating the strength and stiffness of HD/LD polyethylene (PE).

When should I use Tough 2000 resin?

Tough 2000 Resin offers more advanced mechanical properties and a new dark grey look. It is ideal for:

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

Choose Tough 2000 Resin for prototyping strong and sturdy parts that should not bend easily, such as housings and enclosures, jigs and fixtures, mechanical connectors, and prototypes undergoing wear and tear.

You can use this resin with applications across engineering, product design, and manufacturing. Tough 2000 resin can be printed for prototypes undergoing wear and tear, mechanical connectors, and housing and enclosures such as the below motor mount.

The improved strength, stiffness, and elongation allow engineers and product designers to iterate with higher confidence and reduce brittle failures.

Where to find Tough 2000 Resin

You can find Tough 2000 resin in our Formlabs Resin Library where you can either order a sample part or order the actual resin.

Here’s a collection of CAD files you can use with the Tough 2000 resin once you have it in your hands and ready for printing.
