eSun – PET-CF (Black) PET-Carbon Fibre Composite 1.75mm

eSUN PET-CF Carbon Fibre Reinforced PET Filament

Elevate your engineering and functional projects with eSUN PET-CF, a high-performance composite filament designed for professional applications. By reinforcing a robust PET base with high-quality chopped carbon fibres, this material delivers significantly enhanced rigidity, hardness, and wear resistance, making it ideal for creating durable, long-lasting parts.

The standout feature of eSUN PET-CF is its ultra-low moisture absorption. Unlike many other composite materials, it maintains exceptional performance and dimensional stability even in humid environments or when in direct contact with water. This, combined with its good chemical resistance to most acids, alkalis, and solvents, makes it a reliable choice for parts exposed to challenging conditions.

Engineered for reliability, PET-CF boasts excellent printability. The carbon fibre infusion helps to inhibit warping, resulting in a more stable and successful printing process. It prints smoothly without a heated chamber and requires only a moderate bed temperature of 70-80°C.

Compared to nylon-based carbon fiber filaments, eSUN PET-CF offers a high modulus and low creep, ensuring your parts will hold their shape under long-term stress. For applications requiring even higher heat tolerance, the material’s temperature resistance can be further enhanced with a simple post-printing annealing process.

Key Features:

• Ultra-Low Moisture Absorption: Maintains stable performance in humid conditions.
• High Rigidity & Hardness: Carbon fiber reinforcement provides superior mechanical strength.
• Excellent Printability: Low warping and no heated chamber required for reliable results.
• Good Chemical Resistance: Suitable for use in harsh environments.
• High Modulus & Low Creep: Ideal for parts under constant, long-term stress.

Typical Applications:

• Tooling, Jigs, and Fixtures
• Functional Prototypes
• Automotive Components
• Electronics Housings and Parts
• Manufacturing Aids

Printing Recommendations:

• Nozzle: A hardened steel nozzle (or equivalent) is required due to the abrasive nature of carbon fiber.
• Drying: For optimal results, dry the filament at 80°C for 8 hours or more before printing.
• Print Bed: 70-80°C
