Description
Bambu PAHT-CF Overview
Bambu PAHT-CF is a composite material made from PA12 and carbon fiber. By combining the low water absorption of PA12 with the high strength of carbon fiber, it delivers excellent mechanical and thermal performance that remains stable even in wet or high-humidity environments. With enhanced Z-layer adhesion and balanced flexibility, it is ideal for engineering parts such as functional prototypes, machining fixtures, injection molds, jigs, and low-volume production components.
Low Water Absorption
With a water absorption rate approximately 50% lower than that of normal PA-CF, Bambu PAHT-CF maintains excellent mechanical properties and dimensional stability even when exposed to high humidity. This makes it highly reliable for applications where environmental moisture is a concern.
Exceptional Z-Bonding Performance
Bambu PAHT-CF exhibits significantly higher Z-layer adhesion compared to normal PA-CF. This enhanced interlayer bonding allows printed parts to withstand high levels of impact and mechanical stress without cracking, delaminating, or deforming.
High Tensile Strength
Engineered for demanding industrial and engineering applications, Bambu PAHT-CF delivers high tensile strength and durability. It is well suited for functional components that require reliable load-bearing performance and long-term structural stability.
Designed for High-Temperature Resistance
Bambu PAHT-CF offers a heat deflection temperature of up to 194 °C at 0.45 MPa, enabling printed parts to perform reliably in high-temperature environments. This makes it suitable for applications where heat resistance is critical without compromising strength or dimensional accuracy.
RFID-Enabled Intelligent Printing
All print parameters are embedded in RFID and automatically recognized by the Bambu Lab AMS system, enabling seamless material identification and eliminating manual setup steps.
High-Temperature Reusable Spool
Bambu PAHT-CF is supplied on a high-temperature-resistant spool that is not prone to deformation during the drying process. In line with Bambu’s commitment to reducing plastic waste, the spool is reusable and compatible with other Bambu refill filaments.

Printing Tips
•Drying conditions: 80℃ for 8 hrs. PAHT-CF is highly sensitive to humidity. To achieve optimal printing performance, it is recommended further drying before use and after storage. For more details please refer to: Filament drying instructionson 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.
