Bambu Lab PAHT-CF Carbon Fiber Filament 1.75mm – 500g | High-Temperature Engineering Nylon

Product Description

Bambu Lab PAHT-CF is an advanced engineering-grade 3D printing filament made from a high-performance composite of PA12 and carbon fiber. Designed for demanding industrial and professional applications, this filament delivers exceptional mechanical strength, superior Z-layer adhesion, low moisture absorption, and excellent thermal stability.

Unlike conventional PA-CF filaments, Bambu PAHT-CF maintains its mechanical properties even in humid or wet conditions. With up to 50% lower water absorption compared to normal PA-CF, it ensures consistent strength, dimensional accuracy, and durability—making it especially suitable for the humid climate of Bangladesh.

This filament is ideal for functional prototypes, machining fixtures, injection molds, jigs, tooling, and low-volume production parts where high tensile strength, impact resistance, and heat resistance are required.

Low Moisture Absorption Performance

Bambu PAHT-CF has a 50% lower saturated water absorption rate than standard PA-CF filaments, allowing printed parts to retain strength and dimensional stability even under high humidity.

Saturated Water Absorption (25°C, 55% RH)

• Normal PA-CF: 1.70%

• PAHT-CF: 0.88%

Mechanical Property Decline After Moisture Exposure

• Normal PA-CF: 40%–45%

• PAHT-CF: 12%–18%

Drying required: 80°C for 12 hours before printing

Exceptional Z-Layer Bonding

Bambu PAHT-CF offers significantly stronger interlayer bonding compared to normal PA-CF, improving impact resistance and reducing the risk of delamination.

Z-Layer Performance Improvement

• Bending Strength (Z): +27%

• Bending Modulus (Z): +24%

• Impact Strength (Z): +133%

This makes it ideal for mechanically stressed and load-bearing components.
