Recreus Conductive Filaflex - Electrically Conductive TPU, 1.75mm, 500g

* Conductive + Flexible: Print Working Electronics *

Conductive Filaflex is a one-of-a-kind TPU that combines electrical conductivity with genuine flexibility at Shore 92A hardness. It opens the door to printed circuits, pressure-sensitive buttons, and wearable electronics — printed directly on your desktop machine, no specialized hardware required.

Its electrical resistance can be tuned through your print parameters, making it ideal for low-current applications, and it prints on roughly 90% of the printers on the market without a hardened nozzle.

Key Features

• Dual nature — electrically conductive AND flexible (Shore 92A)
• Tunable resistance — dial conductivity in with flow and temperature
• Printer-friendly — no hardened nozzle needed; wide compatibility
• Simple upkeep — purge with PET-G after use to keep the nozzle clean

Great For

• Flexible circuits, pressure sensors and touch buttons
• Wearable tech — prints directly onto textiles
• Arduino keyboards, trackpads and joysticks
• Biomedical experiments like ECG contact patches

Recommended Print Settings

• Dry first (crucial): 55°C for at least 1 hour
• Nozzle: 250°C (0.4 mm) · slow, steady flow — ~4 mm³/s volumetric
• Quirk to know: this TPU stretches as it extrudes, so lines print slightly thinner than the nozzle — bump flow slightly for solid wall bonding and conductivity
