PA6 CF15 filament Spectrum Filaments 1,75 mm / 0,75 kg

Nylon with carbon PA6 CF15

Nylon with carbon Spectrum PA6 CF15 is a high-temperature construction material based on PA6. It has been modified to achieve the best characteristics of carbon fiber significantly increases the mechanical strength of the polyamide on which the material is made. The specific quality of the yarns is that the moisture absorption is halved and the water absorption time is four times lower than that of pure PA6. Printing does not require a heated camera and no deformation occurs. The material is compatible with auxiliary materials HIPS and PVOH.

In addition, Spectrum PA6 CF15 has exceptionally low linear shrinkage (up to 0.1 %), high strain temperature (240 °C) and low coefficient of thermal expansion (0.4 10-5/K).

Parts made of Nylon with carbon PA6 CF15 allow long-term operation at elevated temperatures up to 150 °C (20,000 hours) and up to 180 °C for a short time (max. 200 hours).

To obtain very attractive technical properties of Spectrum PA6 CF15, it is necessary to follow the basic rules of storage of such materials (in a dry and dark place with humidity below 15 %). For best results on the printed object, it is recommended that you dry the material before use.

Tip: Due to the high content of crushed coal, it is recommended to use nozzles with a diameter greater than the standard value of 0.4 mm. The presence of carbon fiber can also cause wear of standard nozzles; therefore for long-term use of Spectrum PA6 CF15 it is recommended to use nozzles from hardened steel or ruby.

Material characteristics

  • Exceptionally low processing (linear) shrinkage of 0.1 %.

  • Industrial modelling.

Nylon with carbon low shrinkage, resistant to abrasion


A 0.75 kg filament is wound on a transparent spool, which contains information about the type of material, diameter, color and recommended printing temperature. Each coil is packed in a vacuum with a dehumidifier. All in the original Spectrum Filaments foil cardboard.

Coil dimensions

  • Outer diameter - 200 mm.
  • Width - 55 mm.
  • Inner diameter - 52 mm.
  • Weight of empty coil - ± 220 g.

Verify quality of 3D plastic thread 

Spectrum Filaments is the only company in Poland and one of the few in the world that has a tool for testing purchased filaments. VERIFY YOUR SPOOL is the most accurate quality control system on the market, ensuring that Spectrum Filaments products meet his stringent requirements.

Filament for 3D printers is produced by free extrusion, which is one of the most difficult extrusion processing technologies, due to the particularly significant influence of process parameters on product dimensions and material homogenization. During the manufacturing process, each 1mm of Spectrum Filaments is continuously measured in 2 axes with an accuracy of ±0.8 µm, resulting in a quality end product. To prove this, Spectrum Filaments, as one of the few manufacturers in the world, has introduced the possibility of an online presentation, individually for each coil produced:

  • diameter travel along the entire length of the coil;
  • average diameter;
  • ovality;
  • standard deviation.
