What drying method is best for Nylon?

Nylon is a highly hygroscopic material, meaning it absorbs moisture quickly from the air. When Nylon filament absorbs moisture, it can cause printing issues like bubbling, poor adhesion, and weak prints. To dry Nylon effectively, it’s important to use methods that can remove moisture thoroughly. Here are the best drying methods for Nylon:

1. Filament Dryer (Dedicated Dryer)

Best For: Consistent and efficient drying, especially for high-moisture filaments like Nylon.

  • How to Do It:
    • Place the Nylon spool in a filament dryer and set the temperature to around 70°C to 75°C (158°F to 167°F), which is ideal for drying Nylon.
    • Let the dryer run for several hours (usually 4-6 hours), depending on the moisture level.
  • Benefits:
  • Recommended Dryers: Sunlu Filament Dryer, PrintDry Filament Dryer, 3D Fuel Filament Drying Oven.

2. Oven Drying

Best For: DIY drying with common household items.

3. Food Dehydrator

Best For: Gently drying Nylon without risking damage.

  • How to Do It:
    • Set the food dehydrator to 70°C (158°F), the optimal temperature for drying Nylon.
    • Place the spool inside the dehydrator and let it dry for 4-6 hours.
  • Benefits:
    • Even air circulation and controlled temperature for consistent drying.
    • Can dry multiple spools at once if needed.
  • Recommended Dehydrators: Excalibur Food Dehydrator, Nesco Food Dehydrator.

4. Vacuum-Sealed Bags with Desiccants

Best For: Long-term storage and gradual moisture removal.

5. Dry Box with Built-In Heating and Dehumidification

Best For: Continuous drying and storage, especially in high-humidity environments.

Best Method for Nylon:

The Filament Dryer or Oven Drying method is generally the best for drying Nylon, as they both allow precise control over temperature, which is crucial for Nylon’s moisture removal. A filament dryer is the most efficient and user-friendly option, especially if you regularly use Nylon or other moisture-sensitive filaments.

If you don’t have access to a dryer or oven, a Food Dehydrator is a good alternative, offering gentle drying without risking overheating.

Always be mindful of the temperature, as excessive heat can damage the Nylon filament.
