Spectrum PET CF15 Filament 1.75mm 0.75kg

Description

Spectrum PET CF15 Filament 1.75mm 0.75kg – Carbon-fiber reinforced PET for very strong, rigid, dimensionally stable technical parts

Spectrum PET CF15 Filament 1.75mm 0.75kg is a black, carbon-fiber reinforced material based on polyethylene terephthalate, developed for demanding technical and industrial applications. It is designed to produce very strong and rigid printed parts while remaining easier to print than many other carbon-filled materials. Spectrum PET CF15 Filament has excellent surface finish directly from the printer, low sensitivity to retraction issues, and it does not require a heated chamber. The material also offers low moisture impact on dimensions, making it a strong choice for precision functional parts.

Key Benefits at a Glance

• Very strong and rigid: Developed for highly rigid printed parts with strong mechanical performance and high Z-strength.
• Carbon-look technical finish: Produces a clean carbon appearance with very good surface quality directly from the printer.
• High temperature resistance: Suitable for demanding environments with long-term service temperature listed at 125°C.
• Good dimensional stability: Low linear shrinkage and low sensitivity to moisture help maintain part accuracy.

Recommended Printing Settings

• Nozzle temperature: 245–270°C
• Heated bed temperature: 50–70°C
• Recommended printing speed: 30–200 mm/s
• Cooling fan: 0–30%

Important Printing Notes

• A heated chamber is not required.
• The material should be stored in a dry, dark place with humidity below 15%.
• Drying the material before printing is recommended for the best printed-part properties.
• Because of the high carbon fiber content, nozzle diameters above 0.4 mm are recommended.
• Carbon fiber can wear brass nozzles over time, so stainless steel nozzles are recommended for prolonged use.
• Spectrum PET CF15 is compatible with support materials such as HIPS-X.

Ideal Applications

• Very strong and rigid functional parts
• Precision technical components
• Parts exposed to static compressive loads
• Slide-bearing and dry-friction components
• Industrial parts exposed to lubricants and oils
• Technical prints where high temperature resistance and dimensional stability matter

Why You’ll Love It

Spectrum PET CF15 Filament is a strong option when standard PETG or standard PET is not rigid enough for the application. It combines a technical carbon-reinforced appearance with high stiffness, strong interlayer bonding, low shrinkage, and high service temperature, while still being easier to print than many other carbon-filled engineering materials.
