You'll probably need to do the export in different sections instead of all at once.

To do that, select just some chunk of your objects (maybe try half of them at first), then use File > Export, which will write only the selected objects out to the file.


Another thing you can do to help reduce memory consumption is to reduce the display mesh density, you've got quite a large number of curvy objects in your model there, and by default things are set to make a fairly high density display mesh which makes things look nice and smooth but which takes up more memory which can add up when you have a large number of objects.

To reduce the display mesh density go to Options > View > Meshing parameters, and set "Mesh angle" to 25 degrees, and uncheck the "Add detail to inflections" checkbox.

That will make for a somewhat more rough/jagged looking display but it should reduce the memory load by quite a bit.
