Z-FLEX is a thermoplastic polyester elastomer that can be 3D printed at a relatively fast rate of 45 mm/s. The filament has great interlayer adhesion and dimensional tolerance falling below +/- 0.02 mm. Z-FLEX is elastic, can bend without breaking, and is resistant to various chemicals including gasoline, ethyl alcohol, butane, and carbon monoxide.
Compared to Z-SEMIFLEX, this filament is a little more elastic and has more rubber-like texture. Besides being able to withstand temperatures as high as 70° C, it can maintain its integrity in low temperatures reaching -40° C. Z-FLEX is perfect for 3D printing parts intended to be bent frequently like tires, elastic hinges, or gaskets.
