Termin8tor cooling duct system

The current printer in the videos had some issues with hot and cold zones after running 1.5 hours or longer. Although not easily apparent, the extra - unevenly hot air under the LCD platform and the much cooler air above the platform and resin was causing parts to stick.
As the hot part progressed and the resin level dropped during the print.
Eventually, the part rises completely out of the resin and the much colder air hitting the plastic causes an adverse reaction such that it lowers back into the hot resin and then as it rises up the next layer it sticks to the FEP film. This sticking makes audible popping sounds and it worsens as the temperature differential between the lower and upper compartments progressively becomes greater the longer the printer runs. Eventually it can tear smaller more delicate prints apart from the excess peeling forces.

To solve this problem, an extra High Pressure 80mm fan replaced the fan lying in the back of the case and a complete duct system w
