About Tough PLA

PLA, or Polylactic Acid, is the single most common polymer used in 3D printing. Tough PLA is a variant of regular PLA that has increased toughness, while retaining many of PLAs other useful properties. An excellent choice for general engineering prototypes, Tough PLA is slightly superior to our Recycled PLA in terms of mechanical properties and surface finish. Both materials however, have good stiffness and dimensional accuracy, while remaining cost-effective.

Tough PLA Gears

It is important to note that like our Recycled PLA, Tough PLA has a low heat deflection temperature, and so should not be used in high temperature applications. Tough PLA is also biodegradable, but only with industrial composting facilities, so please don't add to your regular recycling or compost bins. Tough PLA is perfect for 3D printing prototypes, but if you need a higher quality material - take a look at Onyx.
