Spectrum PET CF15 filament is a high-strength and rigid material based on polyethylene terephthalate (PET) filled with 15% chopped carbon fibers. It combines easy processability with excellent mechanical properties, offering a professional solution for functional parts, prototypes, and technical components.
Key features
PET CF15 is one of the easiest-to-print composite materials filled with carbon fibers. It does not require an enclosed heated chamber, exhibits minimal shrinkage (only 0.1%) and negligible water absorption (below 0.3% at 23 °C/24 h). The material is characterized by high hardness, stiffness, and creep resistance, excellent impact toughness, and very robust interlayer lamination (high Z-strength). It withstands short-term temperatures up to 125 °C, is chemically resistant to lubricants and oils, and offers good tribological properties including dry friction conditions. Straight from the printer you get a matte surface with a professional appearance without the need for additional finishing. Similar to PETG, PET CF15 offers stable printing, plus significantly higher stiffness thanks to the presence of carbon fibers.

Who is Spectrum PET CF15 filament suitable for
The material is intended for advanced users and professionals who need functional parts with high mechanical resistance and dimensional stability. It is used in the automotive industry, in the production of textile components, office machines, parts for precision equipment, and engineering applications. It is suitable for the production of tools, functional prototypes, sliding bearings, and end-use parts. Thanks to its high stiffness and creep resistance, it replaces common PLA and some technical materials such as ABS or nylon in many applications.
Printing tips
- Use nozzles with a diameter larger than the standard 0.4 mm - 0.5 mm and larger is recommended.
- Due to the abrasive effect of carbon fibers, choose stainless steel or hardened steel nozzles; a brass nozzle will wear out quickly.
- Always dry the material before printing at 70 °C for 4-6 hours - moisture significantly degrades print quality and mechanical properties.
- Store the filament in a dry and dark place at a relative humidity below 15%, ideally in sealed boxes with desiccant.
- A heated chamber is not required, but good first-layer adhesion is essential - use glue or a PEI bed.
- For maximum mechanical properties, printed parts can be further annealed (tempered).
- Reduce the print speed compared to standard PETG to achieve better interlayer bonding and a cleaner surface.
- The material is compatible with HIPS-X support material for printing complex overhangs.
