- It is recommended to store filament in sealed bags with desiccant after drying to prevent re-absorption of moisture.
6. Вирішення проблем
If you encounter issues with your 3D prints, consider the following common problems and solutions related to filament moisture:
- Stringing, Blobs, or Zits: These are common indicators of wet filament. Ensure your filament has been adequately dried using the recommended settings for its material type.
- Clogging or Extrusion Issues: Moisture can cause steam bubbles during extrusion, leading to clogs. Dry your filament thoroughly before printing.
- Poor Layer Adhesion: Wet filament can result in weaker layer bonds. Drying the filament can significantly improve print strength and adhesion.
- Шумна робота: The S1 Plus is designed for low noise operation. If you experience unusual or excessive noise, ensure the unit is on a stable surface and there are no obstructions to the fan or filament spool.
