CarbonX™ HTN+CF (High Temp CF Nylon) Printing Filament
CarbonX™ HTN+CF is made using a semi-aromatic High Temperature Nylon [HTN] and a specialty carbon fiber ideally suited to high-temp polyamides. HTN+CF is a go-to for demanding applications that require excellent thermal, mechanical, and chemical resistance – along with ease of printing.
CarbonX™ High Temp CF Nylon is an advanced, semi-aromatic polyphthalamide (PPA) reinforced with high-modulus carbon fiber. This polymer is widely used for metal replacement applications that must resist high mechanical loads at elevated temperatures and aggressive chemical environments. HTN has traditionally been a go-to material for demanding applications in automotive, aerospace, oil & gas, electrical, electronics, and industrial markets.
Benefits of HTN+CF High Temp CF Nylon Include:
- High thermal properties, with a Tg of 125°C, HDT of 240°C, and Tm of 265°C
- Excellent strength and stiffness over a wide temperature range, up to 240°C, higher than ULTEM™ PEI
- Very low moisture absorption yielding improved retention of mechanical properties even when exposed to humid environments
- Outstanding chemical resistance to alcohols, acids, automotive and jet fuels, oils, lubricants, brake and transmission fluids, antifreeze, and Zn/Ca Chlorides
1.75mm and 2.85mm +/- 0.05mm in diameter
Recommended Print Settings:

Carbon Fiber Reinforced Filament
Fibers 5-10 micrometers wide made of carbon. The fibers are aligned following the axis of the material.
This, along with their physical makeup, are what give this material its excellent properties.
Carbon Fibers demonstrate a lot of desirable material properties:
- High stiffness
- High tensile strength
- High heat tolerance
- High chemical resistance
- Low weight
- Low thermal expansion
Reinforcing plastic with carbon fibers produces a 3D printing filament which exhibits the best properties of both the carbon fibers and the plastic of choice.
Ideal for any applications which require light weight and rigidity.
Carbon fiber reinforced parts, designed to use less material and save weight, is extremely popular in aerospace, civil engineering, the military, and motorsports.
This material is particularly abrasive among 3D printing filaments. Users may find standard brass nozzles are chewed through very quickly compared to standard wear and tear. When worn through, the nozzle diameter will widen inconsistently and the printer will experience extrusion issues. Use hardened steel nozzles with this filament to maximize toolhead life and quality of your prints!
Because of this, it's strongly recommended this material be printed through a hardened steel nozzle rather than a softer metal. Hardened steel nozzles can often be inexpensive and easily installed depending on your printer manufacturer's instructions.
