Meet ePA12-CF, a high-performance carbon fiber filled nylon filament designed for engineers and makers who demand precision, strength, and repeatable results in every print. With an advanced 85% PA12 and 15% carbon fiber formulation, this 1.75 mm filament blends the toughness of nylon with the stiffness and wear resistance of carbon fiber for parts that perform under real-world conditions.
- Ultimate combination of strength and stiffness: Tensile strength up to 108.18 MPa and a flexural strength of 116.58 MPa, delivering robust components that resist bending and fatigue in demanding applications.
- Excellent dimensional stability and low shrinkage: Designed for accurate, repeatable parts with smooth layer adhesion and minimal warping, even in complex geometries.
- Low moisture uptake: Engineered for use in wet or humid environments without compromising performance or print consistency.
- Wear resistance and abrasion tolerance: Carbon fiber reinforcement enhances wear life in moving parts and contact surfaces, extending service life in prototyping-to-end-use transitions.
- Printed surfaces with good finish: Delivers a smooth surface and crisp features, ideal for functional prototypes and ducts, housings, and lightweight structural members.
- Note on tooling: As an abrasive material, it can wear out brass 0.4 mm nozzles quickly. For best results, use hardened steel nozzles (0.6 mm or larger) to maintain consistent extrusion over long prints.
- Temperature and environment readiness: Suitable for high-temperature operation with a continuous service temperature up to 120°C and short-term exposure up to 160°C. Print at 280–300°C with a bed temperature of 45–60°C for optimal results; enclosure and controlled ambient temperature help achieve the best layer adhesion and finish.
Why designers choose ePA12-CF
This filament is ideal for robots, drones, automotive, and aviation components where strong, lightweight, and dimensionally stable parts matter. The carbon fiber boost translates to better stiffness without a dramatic weight increase, enabling precise tolerances in functional parts like housings, brackets, and structural members. The improved printability, reduced warp, and reliable layer bonding mean fewer failed prints and faster iteration cycles.
