Spectrum PC/PTFE NAT filament is an advanced composite material based on polycarbonate (PC) with an admixture of PTFE (Teflon), combining high mechanical strength with exceptionally low friction and abrasion resistance.
Key properties
This composite combines the advantages of two engineering materials. Polycarbonate provides high mechanical and thermal resistance, while PTFE reduces wear, friction, and improves chemical and water resistance. The result is a filament with excellent thermal stability, enhanced electrical insulation, and very strong layer lamination. The material exhibits low linear shrinkage during processing (approx. 0.6%), a heat deflection temperature (HDT) of 140 °C, and a Vicat softening point of 145 °C. The flammability rating according to UL 94 (3.0 mm) reaches class V1, and electrical resistance is 1E12 Ohm. The static coefficient of friction is 0.18, dynamic 0.14. Printed parts can be further mechanically machined to achieve a perfectly smooth surface, and the material allows the production of geometrically complex parts while maintaining dimensional accuracy.

Who is Spectrum PC/PTFE NAT filament suitable for
The material is intended for advanced users and industrial applications where a combination of mechanical strength, thermal resistance, and low friction is required. It is ideal for the production of functional parts, low-load gears and transmission elements, sliding components, manufacturing jigs, and assembly tools. It is also suitable for producing parts providing thermal and electrical insulation, functional prototyping, and end-use parts where common materials such as PLA or PETG are insufficient.
Printing tips
- Always thoroughly dry the material before printing - PC/PTFE is hygroscopic and moisture significantly degrades print quality and mechanical properties.
- Print in an enclosed printer with a heated chamber - high thermal stability during printing is key to strong layer lamination and minimizing deformation.
- Use a hardened nozzle (e.g., hardened steel or with a carbide coating) - the PTFE component can wear out a standard brass nozzle.
- Ensure quality bed adhesion using specialized glues designed for polycarbonate.
- Turn off or significantly reduce part cooling to prevent weakening of the interlayer bond.
- Print more slowly - lower print speed significantly improves interlayer adhesion and detail quality.
- If you do not use the material for a longer period, store the spool in a sealed package with a moisture absorber.
