Product variants
Spectrum PC CF is an advanced technical filament based on polycarbonate reinforced with 10% chopped carbon fibers. It combines the excellent mechanical strength, stiffness, and thermal resistance of polycarbonate with the dimensional stability provided by carbon fibers. It is designed for demanding engineering and industrial applications where standard materials such as PLA or PETG are not sufficient.
Key features
The material is based on Spectrum PC 275 enhanced with 10% chopped carbon fibers. This gives it high impact resistance, excellent dimensional stability, and minimal shrinkage. Thermal resistance reaches HDT B 140 °C and Vicat 150 °C, and the material retains good UV resistance as well as resistance to chemicals, moisture, and abrasion. Carbon fibers give the prints a matte, professional-looking finish and allow printing of large parts even without an enclosed heated chamber.

Who is Spectrum PC CF 1.75mm 1kg filament suitable for
The filament is designed for advanced users and professionals who need a reliable material for functional prototypes, mechanical parts, automotive and electronic components, industrial tools, or sports equipment. It excels wherever a combination of high stiffness, thermal resistance, and dimensional stability is required. The smaller 250 g spool is practical for test prints and small production runs without the need to purchase a full-kilogram spool.
Tips for use
- Use a hardened steel or ruby nozzle - carbon fibers rapidly wear out standard brass nozzles.
- The recommended nozzle diameter is 0.5 mm or larger for better fiber flow.
- Dry the filament before printing at 80 °C for 6 - 8 hours; PC is highly hygroscopic.
- Print in an enclosed space without drafts to prevent local cooling and delamination.
- Use an adhesion aid (glue, Magigoo PC) and a PEI or glass build plate.
- Keep part cooling to a minimum, ideally off, for better interlayer strength.
- After opening, store in a dry box with silica gel so the material retains its mechanical properties.
