Bambu Lab PAHT-CF
Bambu Lab PAHT-CF is a carbon fiber reinforced high-temperature nylon filament.
Bambu PAHT-CF is a composite material made from PA12 and carbon fiber. Bambu PAHT-CF combines the advantages of PA12's low water absorption and high-performance carbon fibers, offering excellent mechanical and thermal properties that remain stable even when the prints get wet. Increased Z-layer adhesion and flexibility make it ideal for producing technical parts such as functional prototypes, machining fixtures, injection molds, jigs, and small-batch production parts.
Low Water Absorption
With a 50% lower water absorption rate compared to regular PA-CF,
Bambu PAHT-CF maintains excellent mechanical properties and dimensional stability, even when exposed to high humidity.
Performance from Dry to Wet
Exceptional Z-Bonding
Bambu PAHT-CF exhibits much higher Z-layer adhesion compared to regular PA-CF,
allowing it to withstand strong impacts or loads without breaking or deforming.
Z-Layer Performance
| Regular PA-CF | PAHT-CF | Improved % | |
| Flexural Strength – Z/MPa | 48 | 61 | 27 % |
| Flexural Modulus – Z/MPa | 1470 | 1820 | 24 % |
| Impact Strength – Z/(kJ/m²) | 5.7 | 13.3 | 133 % |
*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 requirements of various industries
and technical 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℃ (0.45 MPa)*, making it suitable for applications where the printed parts may be exposed to high temperatures without deforming or losing their strength.
*The long-term temperature resistance depends on the structure and usage scenario of the model itself.
Accessory Compatibility
| Recommended | Not Recommended | |
| Build Plate | High Temperature Plate - Engineering Plate | Cooling Plate |
| Hotend | Hotend with hardened steel nozzle (0.6 mm, 0.4 mm, 0.8 mm)* | Hotend with stainless steel nozzle (all sizes) Hotend with hardened steel nozzle (0.2 mm) |
| Glue | Glue Stick | Liquid Glue |
*As nozzle size increases, the likelihood of clogging decreases, but print quality also diminishes. Therefore, a 0.6 mm hardened steel nozzle is recommended to prevent clogging while maintaining optimal print quality.
