3D printing enthusiasts know that filament quality is paramount. But how can you tell if your filament has become damp? Here are the tell-tale signs:
- Brittleness: When filament absorbs moisture, it can become brittle and snap easily.
- Stringing: Moisture in the filament turns to steam during printing, causing fine strings of plastic between printed parts.
- Popping or Hissing Sounds: As the filament passes through the hot end, moisture evaporates, creating audible pops.
- Dull Finish: Instead of a smooth, shiny surface, your prints may have a rough, matte finish.
- Poor Adhesion: Damp filament may not stick well to the bed, leading to warping or misshapen prints.
And the problems aren’t just cosmetic:
- Clogged Nozzles: The steam can cause bubbles that solidify inside the nozzle, leading to blockages.
- Weak Prints: Moisture can degrade the integrity of the plastic, resulting in weaker structural strength.
- Reduced Precision: Inconsistent extrusion due to moisture can lead to inaccuracies in the print dimensions.
To ensure the best printing results, store your filament in a dry, airtight container with desiccants. If your filament does get damp, all is not lost – consider using a filament dryer or oven to carefully remove moisture before printing.
