Zortrax Z-FLEX

Z-FLEX is a thermoplastic polyester elastomer that can be 3D printed with at a relatively fast rate of 45mm/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. 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.

Features & Benefits

Features
  • A shock absorber dust cover. 

A shock absorber dust cover 3D printed with Z-FLEX to obtain both flexibility and high chemical resistance of the part.

  • Fast extrusion

Z-FLEX can 3D print at a relatively high rate of 45 mm/s. This makes this filament faster to 3D print with than most flexible materials.

  • Low temperature resistance

Z-FLEX can maintain its integrity in temperatures as low as -40° C. It's perfect for models intended for very cold environments.

  • Chemical resistance

Z-FLEX is resistant to various chemicals including gasoline, ethyl alcohol, butane, and carbon monoxide. It's great meant to work in industrial settings.
