eSun PET-CF Filament – Carbon Fibre Reinforced PET

Industrial Strength. Reliable Performance. Premium Finish.

eSun PET-CF is a carbon-fibre reinforced PET filament engineered for professional and industrial use. With exceptional rigidity, toughness, heat resistance and low moisture absorption, PET-CF is built for functional parts that need to perform reliably in real-world environments.

Its carbon-fibre texture delivers a clean matte, low-warp finish, making it ideal for high-strength prototypes, end-use components, jigs, fixtures and mechanical parts.

Key Features

• Carbon-Fibre Reinforced for outstanding stiffness and mechanical strength

• Matte Surface Finish for a premium, professional appearance

• High Heat Resistance (75°C, up to 145°C after annealing)

• Low Moisture Absorption – ideal for humid or wet environments

• Excellent Chemical Resistance

• Low Warping & Dimensional Stability

• Abrasion Resistant – long-lasting functional parts

Best For

• Mechanical components & end-use parts

• Jigs, fixtures & tooling

• Automotive and industrial applications

• Electronics housings

• Drones, robotics & machine parts

• High-strength engineering prototypes

Printing Recommendations

• Nozzle: 250–300°C

• Bed: 70–120°C

• Cooling: 0–20%

• Use hardened steel nozzle (carbon fibre is abrasive)
