A Creator's Guide to Using a Filament Dryer Box for 3D Printing

3D printing has become an indispensable tool across various industries, from manufacturing and healthcare to education and creative design. As 3D printing technology advances, enthusiasts and professionals alike are continuously seeking ways to enhance their printing processes and achieve higher-quality results. One essential tool that can significantly improve print quality is the filament dryer box. In this comprehensive guide, we will explore the importance of filament dryers, how to use them effectively, and the benefits they offer.

Why Use a Filament Dryer Box?

Filament materials like PLA, ABS, PETG, and Nylon are hygroscopic, meaning they absorb moisture from the air. Moisture-laden filaments can lead to a host of printing issues, including poor adhesion, surface imperfections, and even nozzle clogs. A filament dryer box helps mitigate these problems by removing moisture from the filaments, ensuring optimal printing conditions.

1. Preparation

  • Gather Your Filaments: Select the filaments you intend to dry. Ensure they are properly spooled to prevent tangling.
  • Load the Filaments: Place the filaments inside the dryer box. If you’re using a dryer box like the FIXDRY DOUBLE-NT1, it can hold either one 3kg roll or two 1kg rolls, providing ample space for your materials.

2. Set the Temperature

  • Determine the Appropriate Temperature: Different filament materials require different drying temperatures. For instance, PLA typically dries well at lower temperatures around 40-50℃, while materials like Nylon may require temperatures up to 70℃.
  • Adjust the Settings: Set the dryer box to the recommended temperature for your filament. The FIXDRY DOUBLE-NT1, for example, can reach temperatures up to 70℃, making it versatile for various filament types.

3. Adjust the Drying Time

  • Set the Timer: Depending on the moisture content and the type of filament, drying times can vary. Most dryer boxes, including the FIXDRY DOUBLE-NT1, allow you to set a drying time ranging from a few hours to 48 hours.

4. Activate the Dryer Box

  • Start the Drying Process: Turn on the dryer box to begin the drying cycle. The built-in fan will ensure even heating and effective moisture removal.
  • Monitor Progress: Many dryer boxes come with an independent humidity detector, like the one in the DOUBLE-NT1, providing real-time data on the humidity levels and ensuring precise control over the drying process.

5. Completion and Storage

  • Check the Filaments: Once the drying cycle is complete, check the filaments for dryness. They should feel dry to the touch and free from any visible moisture.
  • Store Properly: To maintain the dryness of your filaments, store them in airtight containers or resealable bags until they are ready to be used.

Benefits of Using a Filament Dryer Box

  • Improved Print Quality: Dry filaments produce smoother prints with better layer adhesion, reducing the risk of print failures and defects.
  • Extended Filament Lifespan: Removing moisture helps prevent filament degradation, extending the lifespan of your materials and reducing waste.
  • Prevention of Nozzle Clogs: Moisture-free filaments are less likely to cause clogs in the printer nozzle, ensuring a smoother printing process.
  • Versatility: Filament dryer boxes are compatible with a wide range of filament materials, making them suitable for various projects and applications.
  • Cost Savings: By maintaining the quality of your filaments, you can reduce material waste and save money in the long run.


Incorporating a filament dryer box into your 3D printing setup is a game-changer for achieving high-quality, reliable prints. By effectively removing moisture from your filaments, you can avoid common printing issues and enhance the overall performance of your 3D printer. Whether you're a hobbyist or a professional, investing in a quality filament dryer box like the FIXDRY DOUBLE-NT1 can make a significant difference in your 3D printing experience. Embrace the potential of dry filaments and unlock the full capabilities of your 3D printer with this essential tool.
