Bambu PAHT-CF

Bambu PAHT-CF is a composite of PA12 and carbon fiber. It inherits the low water absorption properties of PA12 and the high-performance qualities of carbon fiber. Bambu PAHT-CF offers excellent mechanical and thermal properties, which are retained even when printed parts get wet. The higher Z-layer adhesion and flexibility make the material ideal for creating engineering components such as functional prototypes, machining fixtures, molds, jigs, and low-volume production parts.

Low Water Absorption

With a 50% lower water absorption rate compared to ordinary PA-CF,
Bambu PAHT-CF maintains excellent mechanical properties and dimensional stability even when exposed to high humidity.

Deformation from Dry to Wet

Comparison of Mechanical Properties

Both PA-CF and PAHT-CF need to be dried at 80 °C for 12 hours before printing.

Excellent Z-Binding

Bambu PAHT-CF exhibits significantly higher layer adhesion in the Z-direction compared to regular PA-CF,
giving the material 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.

High Tensile Strength
Bambu PAHT-CF is designed to meet the demands of various industrial and technical applications where high strength and durability are required.

Designed for High Temperature Resistance
Bambu PAHT-CF has a heat deflection temperature of up to 194℃ (0.45 MPa)*, making it suitable for situations where printed parts may be exposed to high temperatures without deforming or losing strength.

*The long-term temperature resistance depends on the model's structure and use scenario.

Reusable Spool
Bambu PAHT-CF comes with a high-temperature resistant spool that does not easily deform during the drying process. In line with our concept of reducing plastic waste, the spool can also be reused with other Bambu refills.

Accessory Compatibility

As the nozzle size increases, the likelihood of clogging decreases, but print quality also diminishes. Therefore, it is recommended to use a 0.6 mm hardened steel nozzle to avoid clogging while maintaining optimal print quality.

RFID for Smart Printing

All print parameters are embedded in RFID, which can be read via our AMS (Automatic Material System).

Load and print! No more time-consuming setup processes.

Print Tips

• Drying conditions: 80 °C for 8 hours. PAHT-CF is very sensitive to moisture. For optimal print performance, additional drying is recommended before use and after storage. For more details, refer to: Filament drying instructions on WIKI.

• Bambu PAHT-CF requires high thermal insulation during the printing process, making it unsuitable for open printers.

• For better print results, please refer to: Printing tips for Engineering materials on WIKI.

• When printing with supports, it is recommended to remove support structures within 2 hours after printing to prevent them from adhering after absorbing moisture. If sticking occurs, dry the model to facilitate removal.

Test Conditions

Filament Conditions:

• Dry Samples: were annealed and dried at 80 °C for 12 hours before testing.

• Wet Samples: were placed under environmental conditions of 25 °C, 55% RH and reached saturated water absorption rate.
