Tips & Tricks
- Dry the filament at 80℃ for 10 hours before use for optimal printing performance. Find filament dryers here.
- PA6-CF is sensitive to humidity; dry it before and after storage.
- Use a Hardened Steel nozzle (0.6mm+) instead of Stainless Steel.
- For stronger prints, dampen and soften them beforehand.
- For optimal performance, absorbing water is not recommended for printing models that require high strength, stiffness, and dimensional stability.
- Remove support structures within 2 hours to maximize post-processing.
- If supports are hard to remove, dry and cool prints before removal.
- Use paint, wax, or waterproof coatings to inhibit water absorption and softening.
