ELEGOO PETG-CF 1.75 mm, 500 g 3D Printer Filament, Black

The ELEGOO PETG-CF Carbon Fiber Filament, Black, 0.5 kg, is a composite printing material formulated for FDM and FFF 3D printers. Integrating 5 per cent carbon fibre into standard PETG increases rigidity, structural strength, and abrasion resistance. This composition suits functional prototypes, structural components, and engineering parts requiring greater stiffness than general-purpose materials. Printed objects exhibit a matte black surface with reduced layer-line visibility, yielding a technical finish. A flexural strength rating of 75 MPa and a flexural modulus of 3340 MPa indicate its capacity to withstand bending forces in demanding applications.

Proper use of this material requires specific hardware and environmental conditions. Optimal extrusion occurs at a nozzle temperature of 255 °C, with a functional range of 240–270 °C. A heated build plate set to 65–75 °C is necessary for adequate first-layer adhesion. Users must maintain an operating humidity between 0 and 20 per cent to preserve material integrity. The filament is compatible with FDM and FFF printers that support 1.75 mm filament and these high temperatures. It ships in a vacuum-sealed package weighing 760 grams in total to protect the hygroscopic material during transit.

• Tensile strength of 51,000 kPa limits stretching under heavy load
• Elongation at break of 9.6 per cent indicates resistance to deformation before fracturing
• Impact strength of 70.7 kJ/m² withstands sudden physical force without shattering
• Density of 1290 kg/m³ defines the physical mass of printed objects
• 5 per cent carbon fibre reinforcement increases structural rigidity over standard PETG
• 500 g of material provides a measured supply for multiple prints
• Vacuum-sealed packaging prevents moisture absorption prior to initial use
