6. Moisture Management
| Storage Tip | Recommendation |
| Sealed Packaging | Keep in an airtight aluminum foil bag to protect against moisture. |
| Use Desiccants | Include desiccants to absorb moisture and maintain dryness. |
| Avoid Sunlight & Heat | Keep away from direct sunlight and high temperatures to prevent degradation. |
| Temperature Control | Keep at room temperature, avoiding extreme heat or cold. |
| Annealing | Heat at 90-100°C for 4-6 hours to enhance hardness, or use directly without annealing. |
7. Troubleshooting Common Issues
| Issue | Reason | Solution |
| Stringing | 1. Printing temperature is too high 2. Retraction setting is improper |
1. Reduce the printing temperature by 5-10℃. 2. Increase the retraction distance and speed to effectively pull the filament away from the nozzle. |
| Popping sounds and poor surface quality | Moisture Impact: Damp filament can cause bubbles or popping sounds during extrusion as moisture evaporates at high printing temperatures. |
1. Dry PET-CF in oven set at 90°C for 4-6 hours. 2. Store the filament in a sealed bag with desiccants. |
8. Enhanced Heat Performance Through Annealing
Experience even higher thermal resistance with our PET-CF filament through a simple annealing process. Post-print annealing at 90°C for 4 hours can significantly improve the heat deflection temperature (HDT) and increase material hardness. This thermal treatment optimizes the crystalline structure of PET, resulting in enhanced thermal stability and mechanical properties ideal for high-temperature applications.
