CoexNylex PA6-CF print settings
Print CoexNylex PA6-CF with a 265–290°C nozzle, an 80–100°C bed and an enclosure, with the fan at 40–80% (off for the first layer), and dry it at 80°C for 8–12 hours. It is abrasive, so use a hardened steel, ruby-tipped or other wear-resistant nozzle.
These are COEX 3D's recommended starting settings, made to match the COEX 3D filament settings tables for every filament we make in Green Bay, Wisconsin. Treat each value as a starting point and adjust it for your printer.
1. Material notes
- Keep filament dry: store it sealed, and dry it again only after the spool has been exposed to air
- Dry an opened spool at 80°C for 8–12 hours
- An enclosure is required
- PA6-CF is abrasive: use a hardened steel, ruby-tipped or other wear-resistant nozzle
- Use a Z-offset slightly higher than for 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
Nozzle temperature: 265–290°C
Bed temperature: 80–100°C
- Wash the bed often for good adhesion: use dish soap and rinse thoroughly to remove oils
- Bed adhesion: use WELD3D or a PVA-based glue stick (e.g., Elmer's)
- Use a brim for tall or large prints
- Keep the ambient temperature stable

| Infill | 100% | 166.67 mm/s |
| Top/bottom | 60% | 100.00 mm/s |
| First layer | 30% | 50.00 mm/s |
0.6mm nozzle (max volumetric speed 31.5 mm³/s)
| Line type | Percentage | Speed |
|---|---|---|
| External perimeter | 50% | 84.68 mm/s |
| Internal perimeters | 75% | 127.02 mm/s |
| Infill | 100% | 169.35 mm/s |
| Top/bottom | 60% | 101.61 mm/s |

| Line type | Percentage | Speed |
|---|---|---|
| External perimeter | 50% | 85.78 mm/s |
| Internal perimeters | 75% | 128.68 mm/s |
| Infill | 100% | 171.57 mm/s |
| Top/bottom | 60% | 102.94 mm/s |
| First layer | 30% | 51.47 mm/s |
5. Retraction settings
Important: Set travel speed to the maximum your machine allows (200–500mm/s). Faster moves give the filament less time to ooze, which reduces stringing.
| Nozzle | Distance | Speed | Z-hop |
|---|---|---|---|
| 0.4mm | 1.0–1.5mm | 40mm/s | 0.2mm |
| 0.6mm | 1.0–1.5mm | 40mm/s | 0.2mm |
| 0.8mm | 1.0–1.5mm | 40mm/s | 0.2mm |
| 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 under 15 seconds: 40% fan speed
7. Troubleshooting
| Problem | Solution |
|---|---|
| Irregular extrusion |
|
| Poor adhesion |
|
| Stringing |

Please note: These printing parameters are initial recommendations based on our experience. They may need adjustment for your specific 3D printer, environmental conditions and the geometry of the part you are printing. Use them as a starting point and fine-tune them for your needs.
