CoexNylex™ PA6-CF - When Engineering Excellence is Non-Negotiable
Technical Printing Guide - COEXNYLEX PA6-CF
1. Material Notes
- Keep filament dry - store properly and dry before use
- If needed, dry at 75°C for 3 hours or more
- Use Z-offset slightly higher than PLA (+0.05mm)
- Enable "Avoid crossing perimeters" to reduce stringing
- Consider using the "Wipe while retract" option
- Enable "Slow down for small perimeters."
- Print outer walls slower for better quality
- Use a minimum layer time of 30 seconds for small parts
- Consider using "Extra Prime Amount" after retraction
2. Temperature Settings
Bed Temperature: 80-100°C
- Wash the bed often for good adhesion - Use dish soap and rinse thoroughly to remove oils
- Use bed adhesion products if necessary (gluestick, WELD3D)
- Use brim for tall or large prints
- Keep the ambient temperature stable
Extruder Temperature: 275-295°C

| 1.0mm | 1.0-1.5mm | 40mm/s | 0.2mm |
6. Cooling Settings
Cooling Configuration:
-
- First Layer: 0% (fan off)
- General Printing: 40% base fan speed
- Bridges and Overhangs: 80% fan speed
- Layers < 15 seconds: 40% fan speed
7. Troubleshooting Guide
| Problem | Solution |
| Irregular extrusion |
1. Dry the filament 2. Check the extruder 3. Reduce speed |
| Poor adhesion |
1. Dry the filament 2. Use adhesive 3. Adjust the first layer |
| Stringing |
1. Dry the filament 2. Adjust retraction 3. Increase travel speed 4. Check temperature |
PLEASE NOTE: These printing parameters are initial recommendations based on our experience. They may need adjustment depending on your specific 3D printer, environmental conditions, and the geometry of the part you are printing. Use these settings as a starting point and fine-tune them according to your specific needs.
