UltiMaker Tough PLA is an impact-modified PLA filament printed by fused deposition modeling, made to be less brittle than standard PLA while printing as easily. As with other extruded PLA, parts consist of fused roads laid layer by layer, so they are strongest within the layer plane and weakest across layers, with small voids between roads and visible layer lines. Low shrinkage keeps warping small, and parts usually need only support removal and optional sanding. Printed parts serve as functional prototypes, jigs, fixtures and tooling that must tolerate handling and impact but not elevated temperatures. Every value on this page is read from UltiMaker's own material data sheet — quoted, cited and dated — and is the maker's statement about printed material, not a measurement by MatWorld; none has yet been reviewed by a person.
