Drying Methods

1. Vision Miner Vacuum Drying Oven

Purpose:
Provides a controlled environment with vacuum conditions to efficiently remove moisture from the filament.

Procedure:

1. Set Temperature & Duration:

   • Set the oven temperature to the recommended drying temperature for your filament (refer to your drying table).
   • Dry the filament for the recommended number of hours (e.g., 12�24 hours for high-performance materials).

2. Maintain Vacuum:

   • Throughout the drying cycle, for optimal results, periodically flush the vacuum.
   • Flushing Process: Advised for best results.
     • Open the vacuum valve to temporarily remove the vacuum.
     • Reapply the vacuum to continue the drying process.

Info: Flushing the vacuum helps remove trapped moisture more efficiently, accelerating the drying process.

2. Drying with 22 IDEX and Vacuum Chamber

Purpose:
Uses the integrated heating and vacuum capabilities of the 22 IDEX printer to dry filament effectively through a combined thermal and vacuum process.

Procedure:

1. Preheat the Machine:

   • Preheat the 22 IDEX to the drying temperature specified in the drying table.

2. Load the Filament:

   • Place the filament spool(s) into the printer�s drying chamber.

3. Drying Process:

   • Allow the filament to dry for the duration outlined in the drying table.

4. Final Vacuum Cycle:

   • Immediately after the drying cycle�and while the filament is still hot�transfer it to the vacuum chamber.
   • Engage the vacuum pump and pull the vacuum for at least 30 minutes.

Info: Performing the vacuum cycle while the filament is hot ensures that any residual moisture boils off effectively.

5. Transfer for Printing:

   • Quickly return the hot, dried filament to the 22 IDEX printer.
   • Maintain the chamber temperature during printing to prevent any moisture reabsorption.

6. Post-Print Storage:

   • After printing, place any unused filament back into the vacuum chamber to keep it dry.

3. Drying Filament Inside the Machine (Without Vacuum Chamber)

Purpose:
Provides an alternative method when a dedicated vacuum chamber is not available. This approach uses the machine�s heated environment to dry the filament but requires additional steps to manage moisture.

Procedure:

1. Setup the Drying Chamber:

   • Turn on the chamber heater and set it to the temperature recommended in the drying table.
   • Place the filament spool(s) inside the drying chamber of your machine.

2. Drying Duration:

   • Dry for the recommended duration based on your filament type.
   • Note: Without a vacuum, the drying process may take longer.

3. Air Flushing:

   • Every 4 hours, open the chamber door briefly to allow the saturated, moisture-laden air to escape.
   • Close the door once fresh, drier air is inside.

Info: Regularly flushing the chamber helps remove trapped moisture and can improve drying efficiency.
