Bambu Lab PAHT-CF

Bambu Lab's PAHT-CF filament is a high-temperature, carbon fiber-reinforced nylon designed for applications demanding superior strength, stiffness, and thermal resistance. Its low moisture absorption ensures consistent mechanical properties and dimensional stability, even in humid environments. Enhanced Z-layer adhesion contributes to exceptional impact resistance and durability, making it ideal for functional prototypes, machining fixtures, injection molds, jigs, and low-volume production parts. For optimal printing performance, it's recommended to use a hardened steel nozzle and dry the filament before use.

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

*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.

*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.

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.

 

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.

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.

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 instructions on 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.
