FormFutura Tough PLA is a 3D printer filament that is roughly 750% more impact resistant than regular PLA filaments. Our Tough PLA filament is a performance PLA that combines durability with ABS-like strength properties and yet it is a significantly stiffer 3D printing material than ABS filaments. Tough PLA exhibits excellent layer adhesion allowing 3D printed objects to achieve similar mechanical strength properties compared to injection molding.
