Prusament PA11 Carbon Fiber

# Prusament PA11 Carbon Fiber

Overview

Prusament PA11 Carbon Fiber is a carbon-fibre-filled polyamide 11 composite from Prusa Polymers for demanding engineering, automotive, aerospace and production applications. PA11 provides excellent heat, chemical and mechanical resistance, while recycled carbon fibres improve dimensional stability and reduce warping.

Prusament states that printed parts can withstand temperatures up to approximately 190°C depending on load. The technical data sheet reports 192°C HDT at 0.45 MPa and 152°C at 1.80 MPa. The material also offers low friction, high wear resistance, strong impact performance and much slower moisture absorption than many other polyamides.

Compared with Prusament PC Blend Carbon Fiber, PA11-CF provides substantially higher documented heat resistance and stronger chemical resistance. Prusament ASA is easier for UV-focused outdoor parts, while Prusament PETG is easier for general-purpose engineering parts.

Technical Specifications

Note: Mechanical and thermal values are manufacturer test results and depend on print orientation, geometry, processing conditions and test method.

Important: Carbon fibres are highly abrasive. Use the recommended hardened wear-resistant nozzle; a standard brass nozzle is not suitable.

Printing Compatibility

Recommended Setup

• 285 ±10°C nozzle
• 110 ±10°C heated bed
• 0.4 mm hardened non-high-flow nozzle
• Special PA Nylon print sheet
• Brim recommended for larger objects
• 20% cooling in the documented TDS setup
• Dry filament before use when needed and keep it in dry storage
• Ventilate the print area or use active filtration

Prusa currently lists profiles for CORE One/+, making the Prusa CORE One+ the strongest directly documented indexed match. The printer's temperature capability covers the material profile, but an appropriate hardened nozzle and PA-compatible build surface are still required.

The Bambu Lab H2D and Creality K2 Plus are also technically suitable high-temperature, fibre-reinforced-material platforms. Both exceed the central 285°C / 110°C thermal requirements, but use printer-specific profiles and wear-resistant hardware because Prusament does not publish a dedicated validation profile for these machines.

The Bambu Lab P2S uses hardened extrusion hardware and reaches the central material temperatures. Its 110°C bed limit means the Prusament profile must remain within that maximum, and exact PA11-CF performance should be validated for the printer.

Important: Prusament states that PA11-CF has very low shrinkage and can print large models without an enclosure. An enclosure is therefore not a material requirement for dimensional stability.

Important: The material produces significant odor. Use good ventilation or an enclosure with active filtration.

Mechanical Profile

Note: These values are useful for comparison but are not guaranteed finished-part design limits.

Chemical, Wear and Temperature Performance

Prusament PA11-CF is resistant to a broad range of chemicals including bases, alcohols, toluene, acetone, motor oil, petrol and diesel. Combined with low friction and wear resistance, this suits gears, moving parts, automotive components and machinery exposed to heat or chemicals.

Prusament describes temperature resistance up to approximately 190°C depending on mechanical stress, while the TDS provides 192°C HDT at 0.45 MPa and 152°C at 1.80 MPa.

Processing and Handling

Print at approximately 285 ±10°C with a 110 ±10°C heatbed. The dedicated TDS used 285°C nozzle, 110°C bed, up to 100 mm/s and 20% cooling. A hardened nozzle is mandatory.

Use the Special PA Nylon sheet or another surface specifically prepared for polyamide. A brim is recommended for larger parts. Despite being a polyamide, PA11-CF has low shrinkage and normally does not require an enclosure for dimensional control.

PA11 remains hygroscopic. Prusa's current drying guide specifies 90°C for 6 hours for PA11 Carbon Fiber and recommends dry storage between uses.

Use good ventilation or active filtration because the material produces noticeable odor during printing.

Colour and Finish

• Black
• Matte carbon-fibre appearance
• 800 g NFC spool
• Recycled carbon fibres from manufacturing waste

Comparison Section

Recommended use: Choose Prusament PA11 Carbon Fiber when extreme temperature capability, chemical resistance, friction performance and durability justify its higher material and hardware requirements. Choose Prusament PC Blend Carbon Fiber for a lower-temperature rigid carbon-fibre composite, Prusament ASA for UV-focused outdoor parts, or Prusament PETG for easier general engineering printing.

Callout Section

Recommended use: Best for demanding automotive, aerospace, industrial and production components exposed to heat, chemicals, friction or mechanical loads. The Prusa CORE One+ has a directly supported Prusa profile, while the Bambu Lab H2D and Creality K2 Plus provide suitable high-temperature hardware when configured and validated for PA11-CF.
