[High Strength & Heat Resistance] SUNLU PA6-CF nylon filament combines 80% PA with 20% carbon fiber, delivering remarkable stiffness, strength, and heat resistance. It offers excellent layer adhesion, making it ideal for demanding applications.  

[Perfect for Industrial Engineering] Engineered for strength and durability, SUNLU PA6-CF filament is suitable for industrial uses that require high torsional, tensile, and impact resistance. Ideal applications include gears, screws, helmets, fan blades, toy car chassis, skateboard parts, and bicycle frames.  

[Superior Heat Resistance] With a heat distortion temperature of up to 209°C, significantly higher than Easy PA, PC, or ASA, PA6-CF is ideal for high-temperature applications like automotive exhaust pipes, motor covers, pot handles, and kettle bases.  

[Optimized Printing Settings]
Nozzle Temperature: 270-280°C  
- Bed Temperature: 100°C  
- Printing Speed: 50-150mm/s  
- Annealing: 80-130°C for 5-12 hours (essential for maximizing heat resistance)  
- Bed Surface: Use a thin coat of PVA glue or Magigoo PA for improved adhesion.  

[Important Notes] 
1. Dry the filament before use: 80°C for 24 hours or 110°C for 4 hours.  
2. Use an abrasion-resistant nozzle (e.g., hardened steel) to prevent wear caused by the filament's carbon fiber content.

Printing Tips

● Nylon 12 is the lowest water absorption of nylon consumables, but based on the characteristics of nylon, compared with other consumables, nylon consumables are more susceptible to water absorption and moisture materials, so the usual storage should be placed in a dry environment (relative humidity of less than 20%)
● After 6 hours of unpacking, drying is required before printing, the recommended drying conditions are: 80°C for 12 hours or 110°C for 4 hours.
It is recommended to apply glue to assist printing to prevent warping. Turn on the cooling fan by 70%.
● Printing PA12-CF with copper nozzles is susceptible to wear and tear. It is recommended to use wear-resistant nozzles, e.g. hardened steel nozzles.

Model post-processing

● The strength of the print can be further improved by annealing the print in an oven at 80°C~130°C for 3-12 hours.

● Note: The annealing effect depends on the structure and size of the model itself and the annealing conditions, some models may warp and deform after annealing.

  • PA12-CF absorbs shocks and resists cracking, even under sudden drops or collisions. Trust it for rugged outdoor equipment, drone components, or structural parts that need to survive harsh conditions without compromising integrity.

  • PA12-CF offers exceptional strength-to-weight ratios, ideal for crafting lightweight yet robust components. Perfect for aerospace frames, automotive parts, or outdoor gear that demands durability without added bulk.

  • Its carbon fiber matrix resists scratches, abrasion, and repeated stress, making it a top choice for functional prototypes, industrial tools, or mechanical parts requiring long-term reliability.

PLA is a food-safe material, but the filament will be added with toner during the production process, and it may also be contaminated by the printing nozzle during the printing process, so we do not recommend you to use PLA to print tableware
