PA6 Neat Natural filament Spectrum Filaments 1,75 mm / 0,75 kg

Heat-resistant PA6 Neat Natural 0.75 kg

Heat-resistant PA6 Neat Natural is a new high-temperature construction material based on PA6. Its main feature is its increased mechanical strength compared to other plastics. The material also has exceptional thermal properties, chemical resistance to oils and lubricants, relatively high resistance to corrosion stimulants and good electrical insulating properties compared to unmodified PA6 or PA66.

Parts made of Spectrum PA6 Neat Natural allow long-term operation at elevated temperatures up to 120 °C (20,000 hours) and up to 160 °C for short-term operation (max. 200 hours), while maintaining sufficient mechanical properties. Filament PA6 Neat is characterized by low linear shrinkage (0.3%) and low water absorption (<0.3 %, 23 °C / 24 h). The above characteristics make it an excellent thread for the professional user to create monochrome prints.

To obtain very attractive technical properties of heat-resistant Nylon, it is necessary to follow the basic rules of storage of such materials (in a dry and dark place with a humidity below 15 %). To obtain the best parameters of printed models, it is recommended to dry the plastic before work.

PA6 Neat Natural characteristics

  • Low linear processing shrinkage (0.3 %).
  • High temperature up to 160 °C for short-time operation (max. 200 h).
  • High temperature up to 120 °C for long-time operation (20.000 h).
  • Heat distortion temperature – HDT A 90°C (ISO 75).
  • Water absorption below 0.3 % (23 °C / 24h).
  • High creep resistance.
  • Good tribological properties, including dry friction conditions such as in slide bearing.
  • Chemical resistance to lubricants and oils.


  • Production of gear wheels and racks, slide bearings, sweep-off gears and guide rolls operated in elevated temperatures up to 120 °C on a prolonged basis and up to 160 °C on a short-time basis.
  • All types of ring and plate seals with an increased chemical and corrosion resistance.
  • End-use parts.
  • Tooling.
  • Functional prototyping.
  • Industrial modelling.

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.
