Bambu PPA-CF — Industrial-Grade Carbon Fiber Nylon Metal-Like Strength • High Heat & Humidity Resistance • Precision Engineering Overview Bambu PPA-CF is a high-performance carbon-fiber-reinforced nylon engineered for demanding industrial and mechanical applications. It delivers exceptional stiffness, strength, and dimensional stability—while maintaining performance in high-heat and high-humidity environments where standard nylons struggle. Product features • Metal-like strength: Up to 48% stronger and 102% stiffer than PA6-CF• Heat resistant: Continuous service up to 227 °C• Humidity stable: Low moisture absorption (~1.3%) for consistent mechanical properties• Precision parts: Minimal warp and creep for tight-tolerance components• Diameter: 1.75 mm ± 0.05 mm (cardboard spool) Printer & hardware requirements • Printers: Enclosed systems only (P1S / X1 / X1E / H2 Series)• AMS: ❌ Not compatible• Nozzle: Hardened steel 0.6 mm recommended (0.4 / 0.8 mm optional)• Avoid: 0.2 mm nozzles and stainless steel tips Recommended starting settings • Drying: 100–140 °C × 8–12 h (oven preferred)• Nozzle: 280–310 °C• Bed: 100–120 °C (use Magigoo or glue stick)• Speed: ≤ 100 mm/s• Build plates: Smooth or Textured PEI• Humidity: < 20 % RH (print and store sealed with desiccant) Mechanical & thermal highlights • Tensile strength: ~168 MPa• Flexural strength: ~208 MPa• Flexural modulus: ~9860 MPa• Impact strength: ~41.7 kJ/m²• HDT (0.45 MPa): ~227 °C• Vicat softening: ~232 °C• Density: ~1.25 g/cm³ Printing notes • Dry thoroughly—moisture will ruin surface quality and strength• Use Magigoo or glue stick for adhesion and plate protection• Higher nozzle temps within range improve layer bonding• Allow parts to cool fully before removal What’s in the box • Filament on cardboard spool ×1• Desiccant ×1 Policy snapshot Filament and consumables are final sale. Any approved return on other items must be brand new and unopened; restocking fees and non-refundable shipping may apply.
