Description

Important Key Features: 

  • Superior Mechanical Properties: The addition of chopped carbon fibres improves the rigidity, stiffness, and wear resistance of carbon fibre 3D printing filament, making it perfect for tough engineering applications. 
  • Exceptional Thermal Resistance: TINMORRY PET-CF filament can withstand continuous use at temperatures of 80-110˚C (after annealing) without any deformation, outperforming standard PETG-CF filament in high-heat conditions. 
  • High Dimensional Stability: The carbon fibres reduce the warping and shrinkage typical of PET during printing, resulting in high-dimensional accuracy and perfect prints. 
  • Moisture Resistance: To avoid material absorption, it is recommended to use airtight storage containers with desiccant during printing, ensuring consistent results throughout your 3D printing projects. 
  • Wear-Resistant Nozzles: Due to the carbon content, we recommend using a wear-resistant steel nozzle (0.6mm recommended, 0.4mm capable) for optimal print quality and to avoid nozzle wear. 

Suitable Applications: 

  • Complex Mechanical Parts 
  • Functional Prototypes 
  • Engineering Components 
  • Automotive Parts 
  • Aerospace and Defence Parts 
  • High-Performance Prototyping 

General Printing Guidelines: 

  • Nozzle Size: ≥ 0.4mm (0.6mm recommended for wear resistance) 
  • Layer Height: ≥ 0.1mm 
  • Enclosure Needed: Yes (recommended) 
  • Printing Temperature: 260°C – 290°C 
  • Bed Temperature: 90°C – 100°C 
  • Print Speed: <100mm/s

Frequently Asked Questions

1. What are the benefits and printing requirements of PET CF filament?

PET CF filament provides a strong, heat-resistant, and dimensionally stable printing material. Key benefits include: 

  • High tensile strength and stiffness due to carbon fiber reinforcement 
  • Minimal warping and excellent layer adhesion 
  • Good chemical resistance 
  • Less moisture sensitivity than Nylon CF 

However, printing PET CF filament requires: 

  • A hardened steel or ruby nozzle (carbon fiber is abrasive) 
  • Nozzle temp: 250-280°C 
  • Bed temp: 70-90°C 
  • Enclosure (optional but improves results) 

This filament is ideal for structural parts, jigs, and mechanical components that need long-term durability. 

2. What are the main advantages of PET CF filament in 3D printing?

PET-CF filament offers several key advantages: 

  • Exceptional mechanical properties: High tensile and flexural strength, stiffness, and impact resistance. 
  • High heat resistance: Maintains structural integrity at elevated temperatures (up to 150°C after annealing). 
  • Low moisture absorption: Ensures consistent performance even in humid environments. 
  • Dimensional stability: Minimal warping and shrinkage, making it suitable for precision parts. 
  • Chemical and UV resistance: Suitable for industrial, automotive, and outdoor applications. 

3. What are the recommended printing requirements for PET CF filament?

To print with PET-CF filament, use: 

  • A hardened steel nozzle (minimum 0.4-0.6 mm) due to the abrasive nature of carbon fibers. 
  • A full metal hot end to handle high print temperatures (typically 250-280°C). 
  • A heated bed (80–110°C) for optimal adhesion. 
  • An enclosed printer is recommended for the best results but not strictly required. 
  • Keep the filament dry before use to avoid print defects. 

4. What are the common applications for parts printed with PET CF filament?

PET CF filament is well-suited for a range of demanding applications that require strong, rigid, and thermally stable parts: 

  • Functional Prototypes: For testing designs that need to withstand real-world stress, heat, or chemicals. 
  • Jigs and Fixtures: Manufacturing aids that require high stiffness and wear resistance. 
  • Automotive Components: Under-the-hood parts, brackets, or custom interior elements that need to endure elevated temperatures and vibrations. 
  • Tooling: Durable tools or molds for various manufacturing processes. 
  • Drone and RC Parts: Lightweight yet strong structural components. 
  • Structural Components: Parts that need to bear significant loads or maintain dimensional accuracy under stress. 
  • Outdoor Applications: Due to good UV resistance (though check specific manufacturer data), it can be used for parts exposed to outdoor elements. 
  • Replacement Parts: For industrial machinery or consumer products where strength and heat resistance are critical.
