2. Safety Instructions
- Ensure the device is placed on a stable, flat, and heat-resistant surface.
- Do not block the ventilation openings during operation.
- Keep the device away from water or other liquids.
- Do not touch the heating elements during or immediately after operation.
- Unplug the device from the power outlet when not in use or before cleaning.
- This device is intended for drying 3D printer filaments only. Do not use it for other purposes.
- Keep out of reach of children.
3. Setup
- Unpacking: Carefully remove the filament dryer box from its packaging. Inspect for any damage.
- Placement: Place the unit on a stable, level surface near your 3D printer or in a well-ventilated area.
- Power Connection: Connect the provided power adapter to the DC24V input port on the dryer box, then plug the adapter into a standard electrical outlet.
- Loading Filament:
- Open the translucent upper lid.
- Place your filament spool onto the wire disc inside the dryer box. The dryer supports 0.5KG and 1KG filament spools with a maximum tray size of Ø200x73(H)mm.
- If you intend to print directly from the dryer, feed the filament through the silk outlet.
- Close the upper lid securely to ensure a sealed environment.

- Setting Temperature:
- Press the "Mode" button to cycle through settings. When the temperature indicator is active, use the "Increase" and "Decrease" buttons to adjust the desired drying temperature.
- Available temperature settings are 50℃, 60℃, and 70℃.
- Refer to the Recommended Drying Temperature Table below for optimal settings based on filament type.
- Setting Drying Time:
- Press the "Mode" button again to switch to the time setting. When the time indicator is active, use the "Increase" and "Decrease" buttons to set the drying duration from 0 to 24 hours.
- The dryer will automatically begin heating once the time is set.
- Monitoring: The display shows real-time temperature and a countdown of the drying time.
- Completion: The device will automatically stop heating once the set time has elapsed.
4.1 Recommended Drying Temperature and Time
The following table provides general guidelines for drying various filament types. Optimal settings may vary based on filament brand, ambient humidity, and desired dryness level.
Image 4.2: Table displaying recommended drying temperatures and minimum drying times for common 3D printing filaments such as PLA, TPU, PP, ABS, ASA, PETG, PC, and PA.
| Filament Type | Temperature | Minimum Time |
|---|---|---|
| PLA | 50℃ | ≥4h |
| TPU | 55℃ | ≥4h |
| PP | 55℃ | ≥6h |
| ABS | 60℃ | ≥2h |
| ASA | 60℃ | ≥4h |
| PETG | 65℃ | ≥2h |
| PC | 65℃ | ≥8h |
| PA | 65℃ | ≥12h |
Note: The maximum temperature can reach 70℃. The drying degree reaches excellent effect after 2 hours for some filaments under normal temperature test, normal heating for 30 minutes, and humidity drop.
5. Maintenance
- Cleaning: Ensure the device is unplugged and cooled down before cleaning. Wipe the exterior with a soft, dry cloth. Do not use abrasive cleaners or immerse the unit in water.
- Storage: When not in use for extended periods, store the dryer box in a cool, dry place, away from direct sunlight and dust.
- Filament Spool: Regularly check the wire disc for any debris or filament residue and clean as necessary to ensure smooth rotation.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | No power supply. | Check if the power adapter is securely plugged into both the device and the electrical outlet. Ensure the outlet is functional. |
| Filament is not drying effectively. | Incorrect temperature/time settings; lid not closed properly; extremely high ambient humidity. | Verify temperature and time settings according to the filament type (refer to Table 4.1). Ensure the lid is fully closed. Increase drying time if ambient humidity is very high. |
| Display shows error or abnormal readings. | Internal malfunction. | Unplug the device, wait 5 minutes, then plug it back in. If the issue persists, contact customer support. |
| Fan is noisy or not operating. | Fan obstruction or malfunction. | Ensure no foreign objects are obstructing the fan. If the fan is not operating or is excessively noisy, contact customer support. |
