Ultimaker Tough PLA
Ultimaker Tough PLA
Ultimaker Tough PLA is a technical PLA filament with toughness comparable to Ultimaker ABS. Ideal for reliably printing technical models at large sizes, our Tough PLA offers the same safe and easy use as regular PLA.
Key Features
With an impact strength similar as 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 temperature above 58 °C.
More reliable than ABS for larger prints, with no delamination or warping. Ultimaker Tough PLA is compatible with Ultimaker support materials (PVA and Breakaway), giving full geometric freedom when designing parts
Food contact and in vivo applications. Long term outdoor usage
or applications where the printed part is exposed to temperatures
higher than 58 °C.
