Bambu Labs PAHT-CF is a specialized filament composed of Polyamide High-Temperature (PAHT) reinforced with carbon fibers. This unique blend aims to significantly enhance both the mechanical and thermal properties of the material, making it ideal for extremely demanding industrial and engineering settings.

Physical Properties

  • Density: Generally ranges from 1.35–1.45 g/cm³
  • Heat Deflection Temperature (ISO 75 0.45MPa): 194 °C
  • Tensile Strength: Exceptionally high, often exceeding 120 MPa due to carbon fiber reinforcement

Aesthetic Quality

This filament usually exhibits a matte, textured finish, giving it a high-tech, industrial appearance. The color palette is generally limited to darker or neutral tones, aligning with the material’s emphasis on functional rather than aesthetic applications.

Durability and Usage

PAHT-CF is known for its remarkable mechanical strength, rigidity, and high-temperature resistance. The added carbon fiber reinforcement makes this material ideal for extreme environments, such as aerospace, automotive, and heavy machinery components, where high stress and temperature are common factors.


Due to its advanced mechanical properties, post-processing Bambu Labs PAHT-CF can be challenging and may require specialized techniques or equipment. Methods like sanding, machining, and painting are achievable but often need particular preparation or specialized adhesives and coatings for optimal results.

Environmental Impact

PAHT-CF is neither biodegradable nor derived from renewable resources, as it’s based on petrochemicals. This makes it less eco-friendly compared to materials like PLA. However, its long-lasting nature can be considered an environmental advantage in applications where component durability reduces the need for frequent replacements. Responsible disposal or recycling is advised to minimize its environmental impact.

In summary, Bambu Labs PAHT-CF filament offers an engineering-grade, high-performance material designed for use in extremely demanding industrial and engineering contexts. While its environmental footprint may not be as light as some other materials, its unparalleled mechanical and thermal attributes make it an essential option for specialized, high-stress applications.
