Elegoo PET-CF Carbon Fiber Black, 1,75 mm / 1000 g

Elegoo PET-CF is a carbon fibre-reinforced PET filament for functional parts that require mechanical stability and heat resistance. It combines low warping with low moisture absorption, making it suitable for precise, durable parts designed to withstand long-term use. The incorporated carbon fibres give prints a subtly matt, finely textured finish straight from the print bed. Layer lines are less noticeable, giving functional parts a clean, professional appearance.

PET-CF is significantly less prone to warping than many other technical filaments and remains flat and dimensionally stable during printing. Parts come off the print bed closely matching the dimensions specified in the original model.

After annealing, PET-CF can withstand temperatures of up to 194 °C while retaining its shape. This makes it a practical choice for parts used near motors, electronics or other heat-generating components where standard materials may soften quickly.

Thanks to its low moisture absorption, PET-CF prints remain stable and dimensionally accurate even in humid environments. This makes it a reliable option for parts that are exposed to moisture over extended periods.
