Prusament PC Blend Carbon Fiber Black 2kg (NFC)

Product Description

Prusament PC Blend Carbon Fiber Black 2kg (NFC) is a professional 3D filament based on a polycarbonate blend (PC Blend) reinforced with carbon fibers. It combines high strength, stiffness, and heat resistance with surprisingly good printability. Compared to pure PC Blend, it offers lower warping, better dimensional stability, and higher resistance to UV radiation and common chemicals.

Thanks to the larger 2kg spool with an NFC chip, it is ideal for serial production, printing large functional parts, and long uninterrupted jobs.

Main Advantages

• Reinforced PC Blend with carbon fibers – significantly higher strength and stiffness than standard PC or PETG
• High temperature resistance – approximately 114 °C, up to around 130 °C after annealing (according to TDS)
• Excellent dimensional stability – very low warping, suitable even for larger models
• Matte black surface – professional technical look, hides minor imperfections
• Good resistance to UV radiation and common chemicals – suitable even for demanding environments
• Lower moisture absorption – pre-print drying is usually not necessary
• Reinforced with recycled carbon fibers – a more ecological choice in the PC-CF material category
• NFC chip in the spool – fast material identification on compatible Original Prusa printers

Typical Use

This filament is primarily intended for advanced users and technical applications:

• Functional and structural parts
  • motor mounts, gear covers, mechanical adapters
  • jigs and fixtures in production, assembly jigs
• Parts exposed to heat
  • fan shrouds, printer parts, mounts near motors or electronics
• Outdoor and industrial applications
  • parts with requirements for UV resistance and chemical resistance
• Larger technical prints
  • robust structural components, brackets, frames, and housings

Printing Recommendations

Warning: The material is abrasive – a hardened steel nozzle (or other wear-resistant material) is required for printing. Using a brass nozzle will lead to its rapid wear.

Recommended Settings (guideline)

• Nozzle temperature: approx. 285 ± 10 °C
• Bed temperature: approx. 110 ± 10 °C (heated bed is required)
• Chamber: enclosed space is not necessary – an advantage over pure PC
• Part cooling: rather low to none (max. approx. 20 %)
• Print speed: medium to higher, as per printer manufacturer recommendations

Bed Surface

• Textured PEI powder-coated sheet – excellent choice, standard IPA cleaning is sufficient
• Smooth PEI sheet – recommended to use a separation layer (e.g., glue stick) to prevent too strong adhesion and surface damage

Material Properties

• Base: PC Blend (polycarbonate blend)
• Filling: carbon fibers
• Resulting properties:
  • high strength and stiffness
  • very good wear resistance
  • high temperature resistance (approx. 114 °C, higher after annealing)
  • low warping, good dimensional stability
  • matte, slightly rough surface
  • lower density than pure PC (due to carbon fibers)

The material is suitable for functional, highly stressed parts that common PLA/PETG/ASA materials cannot handle.

Who is the filament suitable for

• Advanced and experienced users of FDM printers
• Owners of Original Prusa printers (MK3S+, MK4, MINI+, etc.) with a hardened nozzle and heated bed
• Users looking for a reliable PC-CF filament with well-documented properties and profiles

Beginners are recommended to first master printing with PLA and PETG, or ASA, and only then move on to PC Blend Carbon Fiber.

NFC Function

The spool is equipped with an NFC chip, which on compatible Original Prusa printers enables:

• automatic identification of the material type
• loading of recommended print profiles
• more convenient filament inventory management

Summary

Prusament PC Blend Carbon Fiber Black 2kg (NFC) is a top-tier technical filament for demanding users who need very strong, dimensionally stable, and heat-resistant parts with a professional matte surface. Thanks to carbon fiber reinforcement, excellent documentation, and the large 2kg spool, it is ideal for functional prototypes, small-batch production, and long print jobs.

Key Properties:

• PC Blend filament reinforced with carbon fibers for maximum strength and stiffness
• High heat resistance of approximately 114 °C, even higher after annealing
• Excellent dimensional stability and low warping – suitable even for larger models
• Matte black technical finish that hides minor print imperfections
• Good resistance to UV radiation and common chemicals for demanding environments
• Large 2kg spool suitable for serial production and long print jobs
• NFC chip in the spool for easy material identification on compatible Original Prusa printers
• Lower moisture absorption, drying before printing is usually not needed
• Ideal for functional prototypes, structural parts, and industrial use
