Setup
Setting up your SUNLU Filament Dryer Box E2 is straightforward:
- Unpack all components from the box as detailed in the "What's in the Box" section.
- Place the FilaDryer E2 on a stable, flat, and heat-resistant surface.
- Ensure the power switch on the back of the unit is in the 'Off' position.
- Connect the provided power cable to the unit's power input and then to a suitable power outlet.
- Press the power switch to the 'On' position. The display will illuminate.
- Familiarize yourself with the control panel on the front of the unit.
Operating Instructions
Drying Filaments
Drying removes excess moisture from filaments, preventing common print defects like bubbling, stringing, and poor layer adhesion. The FilaDryer E2 offers precise temperature control for efficient drying.
- Open the lid of the FilaDryer E2.
- Place your filament spool(s) inside the chamber. Ensure the spool fits within the maximum dimensions (Φ250×153mm).
- Close the lid securely.
- On the control panel, select the appropriate drying temperature and time based on your filament type. The unit heats rapidly, reaching 50°C in 20 minutes and 70°C in 30 minutes from room temperature.
- Start the drying process. Monitor the display for current temperature and humidity readings.
- Once drying is complete, the unit will notify you. Carefully remove the filament spool(s) using the provided heat-resistant gloves if the unit is still warm.

Annealing Filaments and Printed Models
Annealing is a heat treatment process that relieves internal stress in materials, improving their mechanical properties such as impact resistance, durability, and dimensional stability. This is particularly beneficial for engineering-grade filaments and printed parts.
Figure 6: Explanation of the annealing process and its benefits.
To anneal a filament or printed model:
- Place the filament spool or printed model on the annealing tray inside the FilaDryer E2.
- Close the lid.
- Select the annealing mode and set the temperature and duration according to the specific material's requirements. Refer to the filament manufacturer's recommendations or common annealing profiles for your material (e.g., PA, PC).
- Start the annealing process. The FilaDryer E2 will heat the chamber to the set temperature and maintain it for the specified duration.
- After the heating phase, allow the material to cool gradually inside the closed chamber. This controlled cooling is crucial for effective stress relief and property enhancement.
- Once cooled, carefully remove the annealed material.

Filament Storage
The FilaDryer E2 also serves as an excellent storage solution, protecting your filaments from moisture re-absorption. Its dual-chamber insulated design and silicone seals ensure a dry environment.
- After drying or annealing, you can leave the filament inside the FilaDryer E2 with the lid closed to maintain its dry state.
- For printing directly from the dryer, utilize the silicone-sealed filament ports and PTFE tubing to feed the filament to your 3D printer, minimizing exposure to ambient humidity.

Troubleshooting
If you encounter issues with your SUNLU Filament Dryer Box E2, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit does not power on. | Power cable not connected; Power switch off; Power outlet issue. | Ensure power cable is securely plugged in. Turn power switch to 'On'. Test power outlet with another device. |
| Temperature not reaching set value. | Lid not properly closed; Ambient temperature too low; Faulty heating element. | Ensure lid is fully closed and sealed. Allow more time for heating in cold environments. Contact support if issue persists. |
| Filament still moist after drying. | Insufficient drying time/temperature; Filament heavily saturated; Seals compromised. | Increase drying time or temperature. Pre-dry heavily saturated filaments for longer. Check lid and port seals for integrity. |
| Unusual noises during operation. | Fan obstruction; Loose component. | Ensure air vents are clear. If noise persists, discontinue use and contact support. |
If these steps do not resolve your issue, please contact SUNLU customer support for further assistance.
