Product Details ＋

Looking for Bambu Labs PAHT-CF Filament, Carbon Fiber Nylon Material 1.75mm 1kg in Australia?

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.

Bambu Labs PAHT-CF Filament

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.

Z-layer Performance

	Normal PA-CF	PAHT-CF	Improved %
Bending Strength - Z/MPa	47	70	49%
Bending Modulus - Z/MPa	1470	1700	16%
Impact Strength - Z/(kJ/m²)	5.7	13.3	133%

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

Bambu PAHT-CF needs proper drying before printing: recommended drying temperature is 80 ℃ for 5 hours in filament dryer, or 90 ℃ for 10 hours on heat bed. (Do not exceed 100 ℃ because the spool may melt). For more details please refer to:
Bambu PAHT-CF has high thermal insulation requirements during the printing process, making it unsuitable for use with open-frame printers.
