Bends Before It Breaks

The main difference between Tough PLA and regular PLA is how the material handles stress. While regular PLA can bear a lot of weight, it will suddenly snap once its limit is reached.

The Strength of ABS, Without the Hassle

Tough PLA boasts similar tensile, impact, and flexural strength to ABS. However, unlike ABS, it is incredibly classroom-friendly. It prints safely without harsh fumes and warps significantly less during printing.

Built for Functional Engineering

Because of its enhanced flexibility and durability, Tough PLA is perfectly suited for printing functional student projects, including jigs, fixtures, and more durable projects.
