Prusament PA11 (Nylon) Carbon Fiber is an ideal filament for prototypes in the automotive, aerospace, and hobby industries, given its excellent resistance to heat, chemicals, and mechanical stress. Among the Prusament filaments, PA11-CF has by far the best temperature and chemical resistance. 3D-printed parts withstand up to 190 °C (depending on stress) and have increased resistance to many solvents (NaOH, Methanol, Ethanol, Toluene, Acetone, motor oils, benzene, diesel, etc.). PA11-CF is a material made from castor oil, the carbon fibers used for this material are recycled, the same as for the Prusament PC Blend Carbon Fiber. The best use of the PA11-CF is for making special chemically, mechanically, and heat-stressed parts, such as car engine components.
Nozzle 285±10 °C Heatbed 110±10 °C

Excellent temperature resistance (up to 190 °C)
Great chemical resistance
High impact and wear resistance (very strong and rigid material)
Low friction coeficient
Noticeably less hygroscopic compared to other polyamides
Visually appealing matt black surface
Great dimensional stability – possible to print large models without an enclosure
Uses recycled carbon fibers from the manufacturing process
A special print sheet (or separation layer) is required
Requires hardened nozzle
Lower layer-to-layer adhesion compared to pure PA11
Slightly hygroscopic (absorbs moisture)
Emits odors during printing
It is necessary to use a hardened steel nozzle. Carbon fibers are a highly abrasive material and may damage brass nozzles.
Prusament PA11 Carbon Fiber Black can be printed onto textured or satin print sheets with a thin separation layer made with a glue stick (a separation layer is extremely important). However, the results may not be perfect. This is why we are introducing a new type of sheet - the Double-sided Powder-coated PA Nylon Satin Spring Steel Sheet which was designed specifically for Prusament PA11 Carbon Fiber Black.
If you are using the new PA Nylon Satin sheet, never clean it with IPA, acetone, or other solvents - the surface will deteriorate quickly. Instead, clean the sheet with water only (a drop of dishwashing detergent may be used to clean greasy areas).
We recommend printing in a well-ventilated room because PA11 with carbon fibers may release a noticeable odor into the air and produce ultra-fine particles. Printing on an enclosed 3D printer helps contain the odors and particles, plus the increased temperature may improve layer-to-layer adhesion.
PA11, like other polyamides, is a hygroscopic material (it absorbs air moisture). If the absorbed humidity reaches high values, the print quality will deteriorate. Deterioration occurs after a few days to a month, but if you are unsure or know you have not printed for a long time, we recommend drying the filament at 90°C for 4-6 hours before printing.
