3. Produk Langkungview jeung Fitur

The S2 Filament Dryer Box is engineered with advanced features to ensure optimal filament drying:

• Kipas internal: A fan located at the bottom blows upwards, creating a thermal cycle for uniform temperature distribution and efficient moisture expulsion.
• Pemanasan Sakuriling 360°: Utilizes upper and lower double heating plates for rapid and even heating from top to bottom, drying filaments efficiently.
• Lebar Rentang Suhu: Adjustable temperature from 35℃ to 70℃, suitable for drying various filament types including PA and PC.
• Layar Toél LED: An extra-large 4.6-inch (3.42*2.87 inch) LCD touch screen displays real-time temperature, humidity, selected filament type, and countdown time. It supports switching between Celsius and Fahrenheit.
• Dual Temperature Probes: Ensures accurate temperature detection for precise control.
• LED Marquee Light: Indicates the real-time working status. The speed of accumulation reflects the temperature difference between measured and set values.
• Kontrol calakan: Features intelligent presets for multiple filament types and drying modes, reducing the need for manual settings after initial configuration.
• Filament Hole: Designed to allow printing while drying, with a hole for filament to pass through and for moisture to be discharged.

5. Parentah Operasi

1. Daya Hurung: Once connected to power, the LED touch screen will light up.
2. Setel Suhu: Use the touch screen controls to set the desired drying temperature. The range is 35℃ to 70℃. Refer to the "Reference Settings" table below for recommended temperatures based on filament type.
3. Set Drying Time: Use the touch screen controls to set the drying duration. Recommended times are typically 3-6 hours, but can be extended if needed.
4. Select Filament Type: The S2 features intelligent presets. Select your filament type (e.g., PLA, ABS, PA) from the options on the screen. This helps the dryer optimize its settings.
5. Mimitian garing: Press the "RUN" button on the touch screen to begin the drying process. The LED marquee light will indicate operation.
6. Monitor kamajuan: The screen will display real-time humidity (RH%), current temperature (PV), set temperature (SV), and remaining countdown time.
7. Konversi Unit Suhu: You can switch between Celsius (°C) and Fahrenheit (°F) on the touch screen.

Reference Settings for Filament Drying

The following table provides recommended drying temperatures and times for common filament types. These are general guidelines and may vary based on filament brand and environmental conditions.

Saran:

• Before printing, it is recommended to bake first and then print; after baking, it is better to print while baking.
• When the ambient temperature is too low and the drying oven does not heat up to the set value, it is recommended to extend the baking time for more than 1 hour.
• This table serves as a reference for drying time and temperature of commonly used consumables.

Understanding the Drying Process

During the initial heating stage (0-15 minutes), humidity is removed from the filament, causing the relative humidity inside the box to rise to approximately 50%. During the subsequent moisture evaporation stage (around 120 minutes), the relative humidity drops to about 25% as moisture is expelled.

6. Pangropéa

• beberesih: Ensure the dryer box is unplugged and cooled before cleaning. Wipe the exterior with a soft, dry cloth. Do not use abrasive cleaners or immerse the unit in water.
• Panyimpenan: When not in use, store the dryer box in a cool, dry place.
• Filament Storage: For best results, store filaments in a sealed container with desiccant after drying and when not in use.

7. Cara ngungkulan

• Filament still wet after drying:
  • Ensure the correct temperature and time settings are used for the filament type.
  • If ambient temperature is too low, extend drying time by more than 1 hour.
  • If filament has excessive moisture or environment is very humid, open the box briefly to release accumulated moisture, then quickly close to continue drying. This can reduce overall drying time.

• Poor print quality (e.g., popping sounds, bubbles):
  • This often indicates wet filament. Increase drying time or temperature as per the reference table.
  • Consider drying the filament immediately before or during printing.
