Ultimaker Tough PLA is a technical PLA material (polylactic acid) with toughness similar to ABS. It is ideally suited for printing functional prototypes and tools in larger formats—without the risk of warping or delamination. Ultimaker Tough PLA allows for the same safe and easy use as regular PLA.

Ultimaker Tough PLA filament is designed to be an easy-to-use technical plastic:

• Better machinability than PLA allows for more post-processing techniques
• Similar strength and higher stiffness compared to ABS
• No delamination or deformation for reliable printing of larger parts
• Compatible with PVA and breakaway support materials for full geometric freedom
• Create robust plastic parts

The impact resistance of Tough PLA is closer to ABS than to regular PLA. This means that your 3D-printed parts can be used for more functional applications such as fixtures, manufacturing aids, and tools.

Optimized for large prints: When you need toughness for large models, Tough PLA is an easy-to-print and reliable material—ideal for 3D printing with the larger build volume of the Ultimaker S5.

Realize complex geometries: Designs with intricate curves, fine details, and overhangs can be easily printed with Tough PLA, especially in combination with breakaway or water-soluble PVA support material.
