Bambu Lab PET CF Filament 1.75mm 1KG – Carbon Fiber Reinforced Engineering Material
Bambu Lab PET-CF is a carbon fiber reinforced PET filament designed for demanding engineering applications. With exceptional tensile strength, remarkable thermal resistance, and outstanding dimensional stability, PET-CF outperforms PETG-CF in strength and temperature resistance. The low moisture absorption makes it ideal for functional parts in high-humidity environments.
Perfect for automotive accessories, mechanical assemblies, fixtures, and any application requiring superior strength with heat resistance. Requires hardened steel nozzle due to carbon fiber content.
Bambu Lab PET CF Key Features
- Carbon Fiber Reinforced – Increased mechanical strength and stiffness
- Excellent Heat Resistance – Maintains form at elevated temperatures (tested at 70°C and 150°C)
- Low Moisture Absorption – Retains strength in humid environments
- High Dimensional Stability – Resists warping and creep deformation
- Soft Glow Appearance – Professional matte finish
- RFID Enabled – Auto-configuration with Bambu Lab AMS

| Moisture Sensitivity | High (requires drying) | Moderate |
| Best For | High-temp functional parts | General CF applications |
PET CF Applications
- Automotive Parts – Under-hood components, brackets, fixtures
- Mechanical Assemblies – Gears, housings, structural parts
- Industrial Fixtures – Jigs, tooling, end-of-arm tooling
- High-Humidity Environments – Outdoor enclosures, marine applications
- Heat-Exposed Parts – Components near heat sources
- Precision Parts – Where dimensional stability is critical
PET CF Printing Tips
- Dry Before Use – 80°C for 8 hours minimum; highly moisture sensitive.
- Hardened Steel Nozzle – Required; carbon fiber wears brass quickly.
- Enclosed Chamber – Recommended for consistent temperatures.
- Annealing Optional – 80-140°C for 6-12 hours for maximum strength.
- RFID Auto-Settings – AMS automatically configures optimal parameters.

Bambu Lab PET CF FAQ
Q: What’s the difference between PET-CF and PETG-CF?
A: PET-CF has higher carbon fiber content, significantly better strength, and superior heat resistance compared to PETG-CF. It’s designed for more demanding engineering applications.
Q: Do I need to dry PET-CF before printing?
A: Yes, PET-CF is highly moisture sensitive. Dry at 80°C for 8 hours before use and store in a dry box with desiccant.
Q: Can I use a brass nozzle?
A: No, carbon fiber is abrasive and will quickly wear out brass nozzles. Use hardened steel or ruby-tipped nozzles.
Q: Is annealing required?
A: Optional but recommended for maximum strength. Anneal at 80-140°C for 6-12 hours after printing.
