Extreme heat deflection temperature (HDT): Registers a heat deflection temperature of up to 145 °C under 0.45 MPa load conditions, far exceeding the limitations of conventional plastics.
-
Immunity to aggressive fluids: Offers excellent chemical resistance to lubricating oils, fuels, organic solvents, and common industrial cleaning agents.
-
Optimized dimensional stability: Its advanced chemical formulation minimizes the usual hygroscopicity of nylon, ensuring much more predictable printing behavior and exact geometric tolerances.
-
Premium matte surface finish: Naturally conceals print layer transitions, providing a professional aesthetic identical to injection-molded parts.
Product Advantages
PAHT CF15 filament excels in the market due to its real viability for the direct replacement of light metals such as aluminum in machine components. The advantageous strength-to-weight ratio of this composite material substantially reduces the overall weight of moving assemblies and hand tools, optimizing ergonomics on assembly lines and reducing the inertia of automated systems. Compared to other abrasive technical filaments, its internal homogeneity minimizes flow variability at the extrusion head, providing highly consistent production runs throughout the entire spool.

FAQ
What is BCN3D PAHT CF15 filament and what are its recommended applications?
BCN3D PAHT CF15 filament is an industrial-grade technical composite material that combines a high-temperature polyamide (nylon) matrix with 15% short carbon fiber reinforcement. It is especially recommended for manufacturing lightweight metal-replacement structural components, industrial tooling, robotic grippers, and functional mechanical parts continuously exposed to high thermal stress up to 145°C and aggressive chemical fluids.
What nozzle is required to safely print PAHT CF15 material?
To print PAHT CF15 filament, it is essential to use a nozzle with a minimum diameter of 0.6 mm made of high wear-resistant materials such as hardened steel or with a ruby tip. The carbon fibers that make up this material are extremely abrasive and will completely wear out a standard brass nozzle in just a few hours of printing, ruining your extruder's calibration.
What are the optimal drying conditions for PAHT CF15 filament?
According to the manufacturer's specifications, there are two drying guidelines depending on the part's needs:
-
To ensure correct printing without imperfections: The filament must be dried for 4 to 16 hours at 70°C using a conventional hot air dryer.
-
To achieve the optimal mechanical properties specified in the tests: The material must undergo a cycle of at least 40 hours at 80°C in a professional vacuum oven.
Why do mechanical strength values decrease between dry and conditioned specimens?
The polyamide matrix of PAHT CF15 filament naturally absorbs moisture from the environment once printed (a process known as conditioning). By absorbing moisture, the material experiences an increase in elasticity and toughness (the XY plane elongation at break increases from 1.8% to 2.9%), but its pure tensile strength (from 103.2 MPa to 62.9 MPa) and Young's modulus decrease. Understanding this difference under ISO 527 helps engineers calculate the actual safety factors of the part in its definitive working environment.
Is a 3D printer with an active heated chamber needed to use PAHT CF15?
No, an active heated print chamber is not strictly mandatory to process PAHT CF15 filament. However, to control adhesion and prevent warping of the base, a printer equipped with a stable heated bed capable of maintaining temperatures between 100°C and 120°C, configured on glass surfaces or technical PEI sheets, is required.
