ELEGOO PETG-CF 1.75 mm, 1 kg 3D Printer Filament, Carbon Fiber Black

ELEGOO PETG-CF Carbon Fiber Filament is a black, carbon-fibre-reinforced PETG material designed for fused filament fabrication (FFF) 3D printing. The carbon-fibre additive increases rigidity and dimensional stability compared with standard PETG, making it suitable for functional prototypes, mechanical components, and industrial jigs that must resist deformation under load. The material has a flexural strength of 75 MPa, an impact strength of 70.7 kJ/m², and a tensile strength of 51,000 kPa, with an elongation at break of 9.6 %. Each spool contains 1 kg of 1.75 mm diameter filament with a dimensional accuracy of 0.1 mm. Printed parts produce a matte surface finish that reduces the visibility of layer lines. The material has a specific gravity of 1.29 g/cm³ and a melting point of 226 °C.

The recommended extrusion temperature is 255 °C, with an operable range of 240 °C to 270 °C and a build-plate temperature of 65 °C to 75 °C. Print speeds up to 220 mm per second are supported. Because the carbon-fibre reinforcement can accelerate nozzle wear, a wear-resistant nozzle is appropriate for regular use. The filament is compatible with most FDM 3D printers that support 1.75 mm PETG-CF material. The spool measures 200 × 200 × 45 mm and should be stored in environments with relative humidity below 20 %. The material is designed for low warping behaviour during printing, which contributes to stable dimensional results across the printed part.
