Eel Flexible TPU Conductive Filament

Designed and manufactured by one of the leading companies in the development of TPU 3D printing filaments.  NinjaTek the 3D printing business of Fenner Drives located in the USA, have engineered Eel.  A 3D printing filament that is a truly conductive, flexible filament.

Eels 355% elongation and 90A Shore Hardness allows for repeated movement without wear or cracking. Youll produce reliable, high quality prints due to the consistent diameter. NinjaTeks Eel filament is chemical resistant to a variety of materials.

You can take a quick look at how we used the Eel flexible filament on our Buzz Trace at the 2019 Advanced Engineering Show here.

Shore Hardness = 90A

  • Truly flexible Conductive Material
  • 355% elongation allows for repeated movement without wear or cracking
  • Consistent diameter and material properties providing reliable, high quality print
  • Chemical resistant to many materials


Extruder Temperature:  220°C-230°C
Platform Temperature: Room temperature 45°
Glue or blue painters tape is suggested if not using a heated bed.

Print Speed:
Top and bottom layers: 15-20 mm/ sec (900-1800 mm/ min)
Infill speeds: 45-60 mm/ sec (2700-3600 mm/ min)
Layer 2+ use cooling fan if available.

Suggested Applications: Electronic Traces, Integrated flexible wire, Anti Static Grippers, Conductive Wearable Products.

APPROPRIATE ENGINEERING CONTROLS: Ensure sure adequate room ventilation to prevent build up of dust or fumes during printing. Keep processing temperatures below decomposition temperature.
