Formulated right here in the USA using a PA6 copolymer, reinforced with high-modulus carbon fiber, this filament is ideal for anyone that wants a structural component with high modulus, improved chemical and thermal resistance, excellent surface quality, and very easy printing. The Generation 3 has a higher HDT than previous grades (147°C at .45MPa) allowing for expanded use in higher-temp applications.

In the world, you’ll see this type of carbon nylon in Engine Covers/Housings, Cable Insulation and Jacketing, Electrical & Electronic Plastics, Electrical Motor Insulation, Electrical Connectors
motor parts, fuel line connectors, coolant pumps, bushings, bearing pads in aircraft engines, charge air coolers, resonators, engine cover components and heat shields, fuel cutoff and water heater manifold valves, connectors, high voltage bushings, motor housings, and even headlight components.


Nozzle Temperature: 240-270°C
Bed Temperature: 80 - 110°C - for adhesive, our Nano Polymer Adhesive works great!
Chamber Temperature: Heated recommended for larger parts, no special printer required -- yes, you can print this on your Ender 3, Prusa, CR-10, or other standard consumer machine.

Drying: yes, you MUST dry this filament. Like almost every thermoplastic, this does need to be dried thoroughly before processing, which is the fancy word for melting.

Drying Kits can be found here:

Heat Deflect Temp: 147°C
Melt Point: 220 (°C)
Substance: Crystalline

For Tensile strength, you get around 63MPa, but keep in mind the way your part is designed and the orientation at which it’s printed will have a dramatic effect on strength. You’ll lose a certain percentage in the z-axis, depending how the part is printed. All data sheets are available on our online store, at, so you can find the tensile modulus, elongation, impact strength, and more.

CFPA6 has lower UV Resistance than PA12, but with the carbon fiber, it absorbs much of the UV and actually works pretty well over time.
Nylon does tend to break down if used under water, for years at a time.
Good with oils, greases, fuels and hydrocarbons
Nylon is insulating for electrical applications, although the carbon fiber will make it a bit conductive, into the electrostatic dissipative category.

Ideal for parts with high modulus and resistance mixed with great surface finish
Holds dimensional accuracy very well after printing
Usable at a higher range of temperatures than GFPA6
Stronger than PA12, but not as “High temp”
