FF8X NinjaFlex Filament

$ 42,35$ 78,92 excl. VAT


NinjaFlex is the softest flexible filament available for printing everything from shoe soles to RC Car tires. NinjaFlex has a Shore hardness of approximately 85A. You can also vary the hardness of the NinjaFlex printed model, depending on application, by varying the infill percentage and number of outer shells of applied (easily done in the profile settings for Simplify3D).

When printing with NinjaFlex the use of ZYYX SoftSpring™ is highly recommended to ensure stable extrusion. The ZYYX SoftSpring™ is not needed for ZYYX Pro II and printers with upgraded drive system.
It can sometimes be a little difficult to feed the flexible filament through the tubing, so for Pro and Pro II we recommend using the external roll holder and feed it directly to the filament monitor on the back.

Examples of use:

  • Sport shoe insoles
  • Vibration dampers
  • Gaskets
  • Flexible containers
  • Product feet
