We track 1 extrudr TPU-CF listings, with prices checked every 4 hours and normalized to a true cost per kilogram. Below is every listing, sorted by price per kg.
TPU-CF is a base plastic filled with chopped carbon fiber. The fibers make parts stiffer and more dimensionally stable than the unfilled material, but they are abrasive: every carbon fiber filament needs a hardened steel or other wear resistant nozzle. Read the carbon fiber filament guide →
About the base material: TPU (thermoplastic polyurethane) is a flexible, rubber-like filament used for phone cases, gaskets, seals, and vibration dampers. It prints at moderate temperatures but needs a slow, steady feed, and a direct-drive extruder handles it far better than a Bowden setup. Softer grades (lower shore hardness) are more elastic and harder to print.
Best for flexible, rubber-like parts such as phone cases, gaskets, and vibration dampers.
Based on Bambu Lab and Prusa guidance. See the nozzle types guide for brass vs hardened steel.
