5. Moisture Management
|
Storage Tip |
Recommendation |
|
Sealed Packaging |
Store in a sealed aluminum foil bag to prevent moisture. |
|
Use Desiccants |
Add desiccants to absorb moisture and keep the material dry. |
|
Avoid Sunlight & Heat |
Keep away from direct sunlight and high temperatures to prevent degradation. |
|
Temperature Control |
Store at room temperature; avoid extreme heat or cold. |

Β 6. Troubleshooting Common Issues
|
Issue |
Diameter inconsistencies |
|
Solution |
Please check if accidentally used a brass nozzle. It may have widened. |
Β
|
Issue |
Brittle Parts |
|
Solution |
Usually indicates moisture. Dry the filament longer. |
Β
|
Issue |
Clogging |
|
Solution |
Ensure your retraction distance is not too high. Heat creep can cause the fibers to bunch up in the cold zone. |
