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.

*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.

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.


Reusable spool

Bambu PAHT-CF comes with a high-temperature resistant spool, which is not prone to deformation in the drying process. Continuing our concept of reducing plastic waste, the spool can also be reused with other Bambu refills.

*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.

RFID for Intelligent Printing

All printing parameters are embedded in RFID, which can be read through our AMS (Automatic Material System). Load and print! No more tedious setting steps.
