CarbonX™ HTN+CF filament is one of the materials offered by 3DXtech, a renowned North American manufacturer specialising in technical and advanced filaments.

CarbonX™ HTN+CF filament is made from a semi-aromatic high temperature nylon (HTN) combined with a special type of carbon fibre that is perfectly suited to high temperature polyamides. CarbonX™ HTN+CF is an ideal choice for demanding applications that require excellent thermal, mechanical and chemical resistance, without sacrificing some printability compared to other Nylon filaments.

Carbon fibre reinforced filament

In addition to the properties provided by nylon, the CarbonX™ HTN+CF filament is filled with carbon fibres between 5 and 10 micrometres wide aligned along the axis of the material. This, together with its physical composition, gives this material its excellent properties.

The carbon fibre filler improves the properties of the base polymer (high temperature polyamide) by increasing its thermal properties, strength and stiffness, as well as its dimensional stability. In addition, the carbon fibre provides an eye-catching surface finish.

Carbon fibre reinforcement is ideal for any application where lightness and stiffness are required. Carbon fibre reinforced parts are very popular in aerospace, civil engineering, military and motorsport, as they use less material and save weight while maintaining excellent mechanical properties.

Thus, the carbon fibre reinforcement produces a 3D printing filament that enhances the properties of the base polymer, in this case, Nylon.

Some of the most outstanding qualities of the CarbonX™ HTN+CF filament include:

High thermal properties.
Excellent strength and stiffness over a wide temperature range, superior to PEI Ultem™.
Very low moisture absorption, allowing better retention of mechanical properties even when exposed to humid environments.
Excellent chemical resistance to alcohols, acids, automotive and jet fuels, oils, lubricants, brake and transmission fluids, antifreeze and Zn/Ca chlorides.

This material is ideal for users who require the manufacture of lightweight parts that will be subjected to high temperatures without sacrificing rigidity.

The CarbonX™ HTN+CF filament should be printed at a temperature between 285 and 315°C. The recommended bed temperature is between 110 and 120°C. It is recommended to use this filament in a 3D printer with a heated chamber.

To ensure good adhesion to the base and to avoid warping, the use of Magigoo PA is recommended.

The recommended layer height is 60 % of the nozzle diameter used. It is not recommended to print layers smaller than 0.2 mm with carbon fibre reinforced filaments.

This material is particularly abrasive and can cause rapid wear on brass nozzles compared to normal wear. When worn, the nozzle diameter widens inconsistently and the printer experiences extrusion problems that can affect the quality of the 3D printed part. It is therefore recommended to use hardened steel nozzles such as the hardened steel nozzles from E3D or Brozzl. In addition, it is recommended to use nozzles larger than 0.4 mm to avoid clogging.

This material can absorb moisture, so it is recommended to store it in a vacuum container such as those from PrintDry or use a filament dryer such as PrintDry Pro.

If you have an FDM 3D printer with a dual extruder and require 3D printing of complex parts, it is possible to use this material in combination with AquaTek™ X1 UMS, a hot water soluble material.
