BREAKING: Formlabs Launches Tough 2000 Resin

Formlabs has today added a new resin to its engineering range - Tough 2000 Resin.

Tough 2000 Resin is the official replacement for Tough Resin in the Formlabs material library. It’s easily distinguished from its predecessor by its dark grey colour, with the original Tough Resin being blue (see image below).

It is the strongest and stiffest material in Formlabs’ family of functional resins.

Comparing the new resin and old one, Tough 2000 Resin is stronger, stiffer and less brittle. It has increased flexural strength and flexural modulus by roughly 15% and an increased heat deflection temperature by roughly 25%.

Simply put, Tough 2000 is stronger, stiffer and less brittle than its predecessor even at higher temperatures. This is quite an achievement because these values do not typically go up when you increase one or the other. What Formlabs has managed to do is formulate an upgrade over the older Tough Resin across the board.

What is it for?

Because Tough 2000 Resin is the strongest and stiffest material in Formlabs’ family of functional resins, it’s the best choice for making resilient prototypes and manufacturing end-use parts that will undergo wear and tear.

Examples include:

  • Jigs
  • Fixtures
  • Housings
  • Casings
  • Connectors
  • Living hinges

You can also machine Tough Resin 2000 after post-processing.

Now, those of you who are clued up with Formlabs resins will know that the company recently launched Tough 1500 Resin as well. While the two materials can function in the same applications, they are better suited to different applications.

The easiest way to explain the difference between Tough 2000 Resin and Tough 1500 Resin is by comparing them to common plastics -- Tough 2000 Resin simulates the strength and stiffness of ABS, while Tough 1500 Resin simulates the strength and stiffness of polypropylene (PP). In other words, Tough 2000 Resin should be used for parts that should not bend easily, while Tough 1500 Resin should be used for parts that can bend and spring back quickly under cyclic loading.
