Low water absorption
With a 50% lower water absorption rate compared to normal PA-CF, Bambu PAHT-CF maintains excellent mechanical properties and dimensional stability even when exposed to high humidity.
Mechanical Properties Comparison
*Both PA-CF and PAHT-CF need to be dried at 80 °C for 12 hours before printing.

| Impact Strength - Z/(kJ/m²) | 13.3 | 5.7 | 133% |
High tensile strength
Bambu PAHT-CF is designed to meet the demands of various industrial and engineering applications where high strength and durability are required.
Printing Tips
1.Accessory Compatibility
Not compatible with Cool Plate SuperTack, Hotend with Stainless Steel Nozzle 0.2 mm, and Bambu Liquid Glue.
2.Drying Recommendations
PAHT-CF is highly sensitive to humidity. To achieve optimal printing performance, it is recommended to further dry before use and after storage. For more details, please refer to:
Filament drying instructions on WIKI.
3.Usage Guide
- Bambu PAHT-CF has high thermal insulation requirements during the printing process, making it unsuitable for use with open-frame printers.
- When printing a model with support, we recommend removing the support structures within 2 hours after printing to prevent them from sticking after absorbing moisture. If sticking occurs, dry the model to ease the removal.
- For better print results, please refer to printing tips on WIKI.
4.Safety Tips
This product is a carbon fiber reinforced filament that may produce fine fiber debris during use, post-processing, or contact with rough or fractured surfaces, posing a risk of mechanical skin punctures or foreign body irritation. To ensure safety, please avoid rubbing or touching rough edges and cross-sections with bare hands; it is highly recommended to wear gloves when loading or unloading the filament, as well as during cutting, sanding, or other post-processing operations, while using additional protective equipment as required by your specific working conditions.
