The PA11 Carbon Fiber filament from Prusa3D is an advanced engineering solution for FDM 3D printing, designed to offer extreme strength in high thermal, chemical, and mechanical demand environments. Made from polyamide 11 reinforced with recycled carbon fibers, this technical material provides an exceptional combination of structural rigidity, low warping, and durability, making it ideal for professional applications in sectors such as automotive, aerospace, and functional engineering.

Thanks to its heat resistance of up to 190 °C, high dimensional stability, and excellent performance against industrial solvents like acetone, methanol, or oils, PA11 with carbon fiber enables the production of parts exposed to critical conditions. Its matte black surface also delivers a professional finish, while its low coefficient of friction and good wear resistance make it an ideal alternative for functional components, brackets, guides, and mechanical parts subject to friction or continuous stress.

Unlike other polyamides, this filament is less hygroscopic, reducing the need for constant drying and improving long-term print quality. It exhibits minimal shrinkage during manufacturing, making it suitable for printing large parts without an enclosure. However, its use requires certain technical conditions: a hardened steel nozzle is essential due to its abrasiveness, and it is recommended to use a dedicated nylon print sheet or a separation layer to ensure proper bed adhesion.

Due to its excellent impact, tensile, and thermal resistance, this technical nylon filament allows for the creation of functional prototypes and end-use parts that meet the demands of industrial environments. It is a highly specialized option for those seeking performance, reliability, and precision in advanced 3D printing.
