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 Details: 1.75 mm diameter · 500 g spool · Black.
