Open the Flux menu in the top-left corner of the screen. From there, choose the "Export" option and select "Manufacturing Files" to export an archive containing Gerber files.
To export a 3D model of your board, click the Flux menu and choose the "Export" option, and under that "3D Model". The "STEP" file option will output a precise 3D model of just your bare board. The "STL" file option will output a mesh of your assembled board, including all components that have valid 3D models."
