Bambu PAHT-CF Filament
Description
Description
Bambu PAHT-CF Carbon Fiber-Reinforced Polyamide (Nylon) Filament
Bambu PAHT-CF is a composite of PA12 and carbon fiber. Inheriting the advantages of low water absorption from PA12 and high-performance carbon fiber, Bambu PAHT-CF offers excellent mechanical and thermal properties that can be maintained well even when the prints get wet. Higher Z adhesion layers and flexibility make it ideal for creating engineering parts such as functional prototypes, machining fixtures, injection molds, jigs, and low-volume production parts.
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.

| Normal PA-CF | PAHT-CF | Improved % | |
| Bending Strength - Z/MPa | 48 | 61 | 27% |
| Bending Modulus - Z/MPa | 1470 | 1820 | 24% |
| Impact Strength - Z/(kJ/m²) | 5.7 | 13.3 | 133% |
*Both PA-CF and PAHT-CF need to be dried at 80 °C for 12 hours before printing.
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.
Designed for High-Temperature Resistance
The heat deflection temperature of Bambu PAHT-CF is up to 194℃ (0.45MPa)*, making it useful in applications where the printed parts may be exposed to high temperatures without deforming or losing their strength.
*The long-term temperature resistance is related to the structure and usage scenario of the model itself.
Accessory Compatibility

Printing Tips
- Drying conditions: 80℃ for 8 hrs. PAHT-CF is highly sensitive to humidity. To achieve optimal printing performance, it is recommeded further drying before use and after storage. For more details please refer to: Filament drying instructionson WIKI.
- 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 for Engineering materials on WIKI.
