Why Drying Filament Matters

Moisture is one of the most common issues that can ruin your 3D prints. Wet filament can lead to:

• Inconsistent extrusion

• Stringing and blobs

• Poor layer adhesion

• Brittle, weak printed parts
  
  

That’s where a reliable filament dryer box like the Sovol SH02 can dramatically improve print quality, especially for moisture-sensitive filaments such as TPU, PETG, and PA (nylon).
