PAHT-CF
· Low Moisture Absorption · Exceptional Mechanical Properties & Layer Adhesion · High Tensile Strength
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. Deflection from Dry to Wet


Mechanical Properties Comparison
*Both PA-CF and PAHT-CF need to be dried at 80 °C for 12 hours before printing.
| PAHT-CF | Normal PA6-CF | |
|---|---|---|
| Saturated Water Absorption Rate/% ( 25 °C, 55% RH ) | 0.88 | 1.70 |
| Bending Strength - XY/MPa (Dry) | 125 | 128 |
| Bending Strength - XY/MPa (Wet) | 115 | 76 |
| Bending Strength - Z/MPa (Dry) | 61 | 48 |
| Strength (Bending Strength - XY, dry state) | 151 MPa | 141 MPa |
| Bending Strength - Z/MPa (Wet) | 49 | 34 |
| Bending Modulus - XY/MPa (Dry) | 4230 | 4420 |
| Layer Strength (Bending Strength - Z, wet state) | 45 MPa | 31 MPa |
| Bending Modulus - XY/MPa (Wet) | 3640 | 2210 |
| Bending Modulus - Z/MPa (Dry) | 1820 | 1470 |
| Bending Modulus - Z/MPa (Wet) | 1480 | 770 |
| Decline rate of mechanical properties after absorbing water/% | 12%-18% | 40%-45% |
| Saturated Water Absorption Rate / % (25 °C,55% RH) | 2.35 | 3.80 |
Exceptional Z-bonding
Bambu PAHT-CF shows much higher adhesion in Z layers compared to normal PA-CF, bringing it the ability to withstand high levels of impact or stress without breaking or deforming.


Z-layer Performance
*Both PA-CF and PAHT-CF need to be dried at 80 °C for 12 hours before printing.
| PAHT-CF | Normal PA6-CF | Improved % | |
|---|---|---|---|
| Bending Strength - Z/MPa | 61 | 48 | 27% |
| Bending Modulus - Z/MPa | 1820 | 1470 | 24% |
| 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.5.Safety Tips
- Please store the filament in a cool, dark, and dry environment away from direct sunlight and high temperatures.
- Please keep filament and any broken fragments out of reach of infants, children, and pets to prevent swallowing or choking.
- For opened filament, we recommend drying before use according to the wiki’s recommended temperature and time settings.
- Please print this filament in a well-ventilated area, or install an effective air filtration or exhaust system.
- As this filament is not food-grade, please avoid using finished prints for food storage or contact.
- As this filament is highly moisture-absorbent, please place any unused filament in a sealed container with desiccant immediately, and dry thoroughly before printing.
- Please be aware that the filament surface and ends may contain hard microscopic splinters invisible to the naked eye. When handling filament, removing supports, or sanding printed parts, please wear puncture- and cut-resistant gloves and safety goggles.
