Overview

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.

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.

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	Bambu 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.

Highlights

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.

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.

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.

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

Exceptional Thermal Resistance

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.
