Carbon Fiber Reinforced High Temperature Nylon
Bambu PAHT-CF
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.
Mechanical Properties Comparison
| Normal PA-CF | PAHT-CF | |
| Saturated Water Absorption Rate/% ( 25 °C, 55% RH ) | 1.89 | 0.88 |
| Bending Strength - XY/MPa (Dry) | 141 | 140 |
| Bending Strength - XY/MPa (Wet) | 76 | 115 |
| Bending Strength - Z/MPa (Dry) | 47 | 70 |
| Bending Strength - Z/MPa (Wet) | 34 | 58 |
| Bending Modulus - XY/MPa (Dry) | 4480 | 4120 |
| Bending Modulus - XY/MPa (Wet) | 2210 | 3640 |
| Bending Modulus - Z/MPa (Dry) | 1470 | 1700 |
| Bending Modulus - Z/MPa (Wet) | 770 | 1480 |
| Decline rate of mechanical properties after absorbing water/% | 40%-45% | 12%-18% |
*Both PA-CF and PAHT-CF need to be dried at 80 °C for 12 hours before printing.
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
| Normal PA-CF | PAHT-CF | Improved % | |
| Bending Strength - Z/MPa | 47 | 70 | 49% |
| Bending Modulus - Z/MPa | 1470 | 1700 | 16% |
| 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
| Recommended | Not Recommended | |
| Build Plate | High Temperature Plate Engineering Plate | Cool Plate |
| Hotend | Hotend with Hardened Steel Nozzle (0.6 mm, 0.4 mm, 0.8 mm)* | Hotend with Stainless Steel Nozzle (all size) Hotend with Hardened Steel Nozzle (0.2 mm) |
| Glue | Glue Stick | Liquid Glue |
*As the nozzle size increases, the probability of clogging decreases, but the print quality also decreases. Therefore, it is recommended to use a 0.6 mm Hardened Steel nozzle to avoid clogging while maintaining optimal print quality.

Printing Tips
• Bambu PAHT-CF needs proper drying before printing: recommended drying temperature is 80 ℃ for 5 hours in a blast drying oven, or 90 ℃ for 10 hours on heat bed. (Do not exceed 100 ℃ because the spool may melt).
• Bambu PAHT-CF has high thermal insulation requirements during the printing process, making it unsuitable for use with open-frame printers.
