Here are some common mistakes people make when drying filament, and how to avoid them:

1. Using Too High a Temperature

• Mistake: Setting the dryer to a temperature too high for the filament type. Different filaments have different optimal drying temperatures, and using excessive heat can warp or degrade the material.
• Fix: Always refer to the manufacturer’s recommended drying temperature for each filament type. For example, PLA typically dries well at 45-50°C, while Nylon may need around 70°C.

2. Not Checking the Filament Regularly

• Mistake: Leaving filament in the dryer for too long without checking it. Over-drying can lead to brittleness or changes in the filament’s properties.
• Fix: Set a timer for the drying process, and try to monitor the filament. If possible, check after a few hours to ensure it isn’t over-dried.

3. Drying Filament That Isn’t Moist

• Mistake: Using a filament dryer when the filament is not actually moist or damaged by humidity. If filament is already dry, the dryer won’t improve its quality and can waste energy.
• Fix: Only dry filament that feels brittle or shows signs of moisture-related issues, like popping or bubbling during printing.

4. Incorrect Storage After Drying

• Mistake: After drying, failing to store the filament properly. Exposure to humidity after drying can reintroduce moisture into the filament, making the drying process pointless.
• Fix: Immediately store dry filament in a vacuum-sealed bag or airtight container with desiccants to maintain its dry state.

5. Using the Wrong Dryer for the Job

• Mistake: Using a filament dryer that isn’t suitable for the type or size of filament you’re working with. Not all dryers are built to handle all filament types, and some may not have the necessary airflow or temperature control.
• Fix: Choose a filament dryer that’s designed to accommodate the type of filament you use most often, and consider its capacity and features before purchasing.

6. Ignoring Filament Spool Compatibility

• Mistake: Not considering spool size or compatibility with the dryer. Some filament spools may not fit properly in certain dryers, leading to uneven drying or a longer drying process.
• Fix: Ensure that your filament dryer can handle the spool sizes you use regularly, and adjust the setup to ensure even drying.

7. Overloading the Dryer

• Mistake: Trying to dry too many spools at once, which can reduce the effectiveness of the drying process. Overloading the dryer can lead to uneven drying.
• Fix: Stick to the recommended load capacity for your dryer and prioritize drying one spool at a time for optimal results.

By avoiding these mistakes, you can ensure your filament stays in excellent condition and is ready for use when you need it!
