How to Dry Out ABS Filament: A Step-by-Step Guide

After PLA filaments ABS filament is the second by popular choice for the 3D printing industry due to its strength and durability. However, ABS filament is hygroscopic (tending to absorb moisture from the air), meaning it absorbs moisture from the surrounding environment. We all know that this moisture can negatively impact the quality of your prints, leading to issues like warping and poor layer adhesion. How to avoid this issue and to ensure optimal print results, it is essential to dry out your ABS filament before use. In this article, we will guide you through the process of drying out ABS filament effectively.

Step 1: Assessing Filament Moisture
Before starting the drying process, it’s crucial to determine the moisture content of your ABS filament. If you notice any signs of moisture, such as a rough or discolored surface, it’s a clear indication that drying is necessary.

Step 2: Preparing a Filament Dry Box
To create an ideal environment for drying ABS filament, you will need a filament dry box. This can be airtight plastic container or a specialized filament dry box that provides a controlled and dry atmosphere. Ensure the container is clean and free from any moisture-trapping materials.

Step 3: Prepare the Filament
Next, remove the ABS filament from the spool and cut it into smaller, manageable lengths. This will help increase the surface area and speed up the drying process. Avoid using scissors or blades that may introduce moisture or contaminants.

Step 4: Place Filament in the Dry Box
Place the cut ABS filament pieces into the filament dry box, ensuring they are evenly spread out and not overlapping. Close the lid tightly to create an airtight seal, preventing any moisture from entering the box.

Step 5: Add Desiccant Packs
To aid in the drying process, add desiccant packs to the filament dry box. Desiccants, such as silica gel or molecular sieve, help absorb any remaining moisture in the container. Use enough desiccant packs to cover the entire surface area of the filament.

Step 6: Allowing Sufficient Drying Time
Leave the ABS filament in the filament dry box for an extended period to ensure thorough drying. The drying time can vary depending on the level of moisture present and the ambient conditions. As a general guideline, allow the filament to dry for at least 4 to 6 hours, or even overnight, for optimal results.

Step 7: Checking Filament Dryness
After the drying period, remove a small section of the ABS filament and check its texture and appearance. If it feels dry to the touch and has regained its original smoothness, it is likely ready for use. If any signs of moisture persist, continue drying the filament for a longer duration.

Drying out ABS filament is a crucial step to ensure successful 3D prints with excellent quality. Following these steps and taking the necessary precautions, you can effectively remove moisture from your ABS filament, minimizing the risk of print defects caused by moisture-related issues.

Remember to store your dried filament in an airtight container or resealable bag to maintain its dryness until you are ready to use it. There are a lot of dehumidifiers that can keep and extract moisture from the box where you keep/stock your filaments.

With properly dried ABS filament, you can achieve consistent and high-quality prints every time.
