2. Fitur konci

• Large 4 Spool Capacity: The S4 filament dryer (450x210x211mm interior) holds 4 x 1kg filament spools for simultaneous drying. This enables non-stop multi-color projects or feeding multiple 3D printers.
• Efficient Heating to 70℃: The SUNLU S4 3D printer filament dryer provides rapid, uniform heat up to 70°C, effectively drying a wide range of filaments. This ensures optimal filament condition for smoother, more reliable prints.
• Triple-Safe System: Equipped with a 350W PTC heater, backup thermal switch, and software monitoring, the SUNLU filament dryer S4 actively ensures temperature and alerts on anomalies for worry-free drying.
• Kontrol Kalembaban anu Cerdas: Triggered at 30-50% RH and stops under 25% RH, ensuring a consistently dry environment to protect your filament from getting damp deui.
• kasaluyuan luhur: The SUNLU S4 dryer boasts wide compatibility with most FDM 3D printers, which actively dries filament for up to 4 printers concurrently and supports most common diameters (1.75mm, 2.85mm, 3.0mm), making it suitable for multi-printer setups.
• 3 Circulation Fans: The S4 filament dehydrator uses three high-quality fans to circulate air, ensuring a consistent temperature and 360° surround heating for even drying.

4.1 Unboxing sareng Inspeksi Awal

Carefully remove the filament dryer from its packaging. Place the unit on a stable, flat surface. Inspect the dryer for any visible damage that may have occurred during shipping. Refer to the 'Package Contents' section to ensure all accessories are present.

4.2 Installing PTFE Tubes

The PTFE tubes guide the filament from the dryer to your 3D printer. Install the appropriate length of PTFE tube into the designated outlet holes on the dryer, ensuring a secure fit. The shorter 8cm tubes are typically used for direct drive extruders, while the longer 100cm tubes are for Bowden extruders.

4.3 Filamen Muatan

Open the top cover of the dryer. Place your filament spool(s) onto the rollers inside the dryer. Ensure the filament unwinds smoothly. Thread the end of the filament through the installed PTFE tube. If the filament end is bent, cut off the bent portion for a clean feed.

5.1 Powering On and Setting Parameters

Connect the power cable to the dryer and plug it into a power outlet. Press the power button on the front panel to turn on the device. Use the 'SET' key to navigate through the menu options (temperature, time, filament type). Use the up and down arrow keys to adjust the corresponding parameters according to your filament's requirements.

5.2 Filament Drying Guide

Refer to the table below for recommended drying temperatures and times for common filament types. These are general guidelines; optimal settings may vary based on filament brand and environmental humidity.

6. Pangropéa

To ensure the longevity and optimal performance of your SUNLU S4 Filament Dryer, regular maintenance is recommended:

• beberesih: Periodically wipe down the interior and exterior of the dryer with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
• Inspeksi Roller: Check the filament rollers for any debris or wear. Ensure they spin freely to prevent filament tangling.
• PTFE Tube Replacement: If the PTFE tubes show signs of wear or damage, replace them to maintain smooth filament feeding.

7. Cara ngungkulan

If you encounter issues with your SUNLU S4 Filament Dryer, consider the following:

• Filament Not Drying Effectively: Ensure the correct temperature and time settings are selected for your filament type. Verify that the dryer lid is properly closed and sealed.
• Tampilan Teu Gawé: Check the power connection and ensure the power switch is in the 'ON' position.
• Filament Snapping/Brittle: This often indicates insufficient drying. Increase the drying time or temperature slightly, within the recommended range for your filament.
