The Seal button is primarily used to control the auxiliary component cooling fan to balance the chamber temperature.
Seal has two states: ON and OFF.
It can be toggled via the switch in the filament settings panel.
ON
When the Seal button is enabled, the auxiliary component cooling fan defaults to operating at maximum speed, as shown below.
OFF
When the Seal button is disabled, the auxiliary component cooling fan will turn off.
Printing Tip: If you prefer printing with the top cover and printer door closed, it is recommended to enable the Seal function to improve air circulation and heat dissipation within the chamber.
Note: The Sealing function provides limited heat dissipation. During hot weather, it is still advisable to open the top cover and printer door for printing.
