Key Features:

• Automatic 360° Rotation: A geared motor ensures even heating by automatically rotating the filament spool, eliminating temperature variations.
• Large Capacity: Accommodates two 1kg spools (210x170mm) or one large 3kg spool (250x170mm) with an included extension kit.
• Automatic Humidity & Temperature Control: Maintains a set relative humidity level and offers temperature control from 20℃ to 80℃.
• Efficient Heating System: Utilizes a 130W PTC heater and forced hot-air circulation with 8 vents for safe, environmentally friendly, and quiet operation (35-36 dB).
• Storage Box & Spool Holder: Features an adjustable exhaust vent for storage, two desiccant compartments, and small plugs for sealed, dust-proof protection.

2. Setup

2.1 Unboxing and Packing List

Carefully unpack all components and verify against the packing list below:

Figure 2: Detailed packing list and component overview.

2.2 Assembly Procedure

Follow these steps to assemble your Polyphemus filament dryer:

1. Assemble the transparent panels to form the main chamber.
2. Attach the top lid and handle securely.
3. Place the assembled chamber onto the bottom base, ensuring it aligns correctly with the heating and rotation mechanisms.
4. If using for 3KG spools, install the extension kit between the base and the chamber.

2.3 Loading Filament

Open the top lid and place your filament spool(s) onto the rollers inside the chamber. Ensure the filament unwinds smoothly. For optimal drying, remove the magnetic plates from the bottom of the removable boxes to allow warm air circulation during drying. Reattach them for sealed storage.

3. Operating Instructions

3.1 Control Panel Overview

The dryer features an intelligent built-in LCD interface for easy control and monitoring. All setting parameters are clearly indicated on the screen.

3.2 Setting Drying Parameters

The dryer offers preset time and temperature configurations for various filaments. You can also customize settings.

• Filament Type Selection: Choose from predefined modes for PLA, ABS, PETG, PA, TPU, PC, ASA, PVA, PP, or use custom settings (M1, M2, M3).
• Temperature Range: Adjustable from 20℃ to 80℃.
• Drying Time: Default settings from 30 minutes to 24 hours, or set to unlimited.
• Automatic Rotation: Activate the rotating mode for 360° surround heating, especially when not actively printing.
• Automatic Humidity Hold: Activate the humidity mode to maintain a certain relative humidity level, keeping filament ready for use.

4. Maintenance and Storage

4.1 Storing Filament After Drying

After the drying process is complete, you can turn off the exhaust fan and use the provided rubber plugs to seal the ports for better drying conditions. The two compartments are designed for placing desiccants to maintain a dry environment for your filament long-term.

4.2 Desiccant Management

Regularly check and replace or regenerate desiccants in the designated compartments to ensure continued moisture absorption. The dryer's heating capabilities can assist in regenerating certain types of desiccants.

5. Troubleshooting

If you encounter issues with your EIBOS Polyphemus, consider the following:

• Inconsistent Drying/Temperature: Ensure the magnetic plates are removed from the bottom of the removable boxes during active drying to allow proper air circulation. Verify that the selected temperature and time settings are appropriate for your filament type.
• Filament Rotation Issues: Check that spools are correctly seated on the rollers. If the auto-rotation is inconsistent, ensure the spare motor is properly installed or consider replacing it if necessary.
• Humidity/Temperature Display Inaccuracy: While the unit provides readings, external calibrated sensors can be used for verification if precise measurements are critical for your application.
• Air Gaps/Sealing: Ensure all panels and the lid are properly closed and sealed. The small plugs should be used for ports when not actively printing to maintain a dry environment.
