Red Tough PLA plastic 0.75kg. 2.85mm diameter and approximately 90m long. Ultimaker Tough PLA is a technical PLA filament with toughness comparable to Ultimaker ABS. Ideal for reliably printing technical models at larger sizes, our Tough PLA offers the same safe and easy use as regular PLA. Reasons to choose Ultimaker PLA Tough With an impact strength similar and higher stiffness compared to Ultimaker ABS, Tough PLA is less brittle than regular PLA and gives a more matte surface finish quality. Heat resistance is similar to standard PLA filaments, so printed parts should not be exposed to temperatures above 60 C. More reliable than ABS for larger prints, with no delamination or warping. Ultimaker Tough PLA is also compatible with Ultimaker support materials (PVA and Breakaway) giving full geometric freedom when designing parts.
