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

Filament Specifications:

1.75mm +/- 0.05mm in diameter

Recommended Print Settings:

  • Extruder: 285-315°C
  • Bed Temp: 110-120°C
  • Nozzle: We currently recommend using one of our abrasion-resistant Vanadium™ Nozzles with a minimum diameter of 0.4mm.
  • Other: Ideal layer height is 60% of nozzle diameter. We do not recommend printing layers smaller than 0.2mm with carbon fiber reinforced filaments
  • Bed Prep: Magigoo Bed Prep and 3DXTECH Polyimide Tape gives us the best results
  • Heated Chamber: Recommended
  • Supports: AquaTek water soluble X1 USM Universal Support Material is designed to work with complex model geometries
  • Drying Instructions: 90°C for 4 hours

Abrasive Material

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.


Because of this, it's strongly recommended this material be printed through a hardened steel nozzle rather than a softer metal, making our Vanadium Nozzles an excellent choice for this material.
