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 5. Troubleshooting Common Issues

Issue

Stringing / Oozing

Possible Cause

Wet Filament / Temp too high

Solution
  • Dry the filament or print from a dry box.
  • Reduce nozzle temperature by 5Β°C steps.

Β 

Issue

Rough Surface

Reason

Wet Filament

Solution

Moisture causes steam bubbles. Dry the filament.

Β 

Issue

Nozzle Clog

Reason

Retraction too high / Nozzle too small

Solution
  • Reduce retraction distance to < 3 mm.
  • Ensure nozzle is β‰₯ 0.4 mm.

Β 

Issue

Warping

Reason

Bed too cold

Solution

Increase bed temp to 80Β°C and use a brim.
