7. Troubleshooting
If you encounter issues with your 3D prints, moisture in your filament might be the cause. The SUNLU S1 Plus Filament Dryer Box can help resolve common moisture-related printing problems.
7.1. Common Moisture-Related Print Issues
- Stringing: Fine strands of plastic appearing between printed parts.
- Bubbles/Blobs: Irregular bumps or imperfections on the print surface.
- Poor Adhesion: Layers not sticking together properly, leading to weak or delaminated prints.
- Clogging: Filament expanding due to moisture and blocking the printer nozzle.
