Tough PLA is a technical PLA (polylactic acid) material with toughness similar to ABS. Ideal for reliably printing functional prototypes and tooling at larger sizes, our Tough PLA offers the same safe and simple use as regular PLA.
Ultimaker Tough PLA can be printed on Ultimaker S5 and the Ultimaker 3 family printers.
Always use the latest version of Ultimaker Cura and make sure that your 3D printer is updated with the latest firmware version to include the correct material profile for Ultimaker Tough PLA.
Tough PLA is an easy material to print with, the same as regular PLA. It can be printed with an AA print core (0.25, 0.4 and 0.8 mm), and can be combined with Ultimaker PVA, Breakaway, or another color of Tough PLA. This is supported on both the Ultimaker S5 and Ultimaker 3.
Just as regular PLA, Tough PLA prints at moderate temperatures. The nozzle temperature is between 210 and 220 °C and the build plate temperature is set to 60 °C. These temperatures are the same for both the Ultimaker S5 and Ultimaker 3. Depending on the selected profile in Ultimaker Cura there are small differences in the nozzle temperatures. These have been optimized to print properly with the selected print core size and layer height profile.
Tough PLA benefits from good cooling throughout the whole print. The print cooling fan speed is therefore set to 100% in the Ultimaker Cura profiles. Since Tough PLA has a low shrinkage, strong cooling will not cause layer bonding related problems.
Tough PLA adheres well to the glass plate, so printing of the initial layer is usually easy.
For the best results, especially with large prints, it is advised to apply a thin layer of glue to the glass plate.
Printing with Ultimaker Tough PLA doesn’t require any additional accessories. However, you can try the adhesion sheets to use as an alternative adhesion method.
Ultimaker Cura build plate adhesion
In Ultimaker Cura the default build plate adhesion type for all Tough PLA profiles is with a brim. This enables even large models to adhere well to the build plate.
Tough PLA is an easy-to-print material and therefore does not require additional accessories to create a stable printing environment. However, on the Ultimaker 3 you can use the front enclosure from the Advanced 3D Printing Kit to obtain more consistent and reliable 3D prints.
Health and safety
Ultimaker Tough PLA emits a low level of gases and particles when 3D printed in accordance with the recommended temperatures in the table above. To ensure a comfortable and healthy environment, we recommend 3D printing in a well-ventilated area.
