Material Properties & Composition
eSun ePA-CF is an advanced nylon composite filament based on PA6/66 copolymer with 20% chopped carbon fiber reinforcement, achieving a density of 1.24 g/cm³ and exceptional mechanical properties including 140 MPa tensile strength and 4363 MPa flexural modulus. The carbon fiber addition dramatically enhances rigidity, toughness, and impact resistance with an IZOD impact strength of 18.67 kJ/m², while maintaining excellent heat distortion temperature up to 155°C for continuous use. Processing requires elevated temperatures of 260-300°C with heated bed at 45-60°C, delivering superior dimensional stability and a distinctive matte surface finish.
Applications & Use Cases
This industrial-grade filament excels in demanding applications including automotive components, aerospace parts, machinery fixtures, and robotics where metal replacement is feasible due to its exceptional strength-to-weight ratio. Compatible with FDM printers using hardened steel nozzles, it's particularly suited for manufacturing gears, tooling, jigs, conveyor components, and structural parts requiring continuous operation at elevated temperatures. The material finds extensive use in orthotics, prosthetics, protective equipment, and end-of-arm tooling where durability and precision are paramount.
Advantages & Considerations
Key advantages include significantly reduced warpage compared to standard nylon, self-lubricating properties for wear resistance, and flame retardant characteristics with UL94-V2 rating for enhanced safety. The material offers outstanding layer adhesion and dimensional accuracy while maintaining low moisture absorption, making it less sensitive to environmental humidity than traditional nylon. Users must employ hardened steel or ruby nozzles due to the abrasive carbon fibers, require thorough filament drying at 70°C for 12+ hours before printing, and should avoid excessive bending in feed systems to prevent jamming.
