Cannot save part as STL file

Hi,

I made a cylindrical array of spheres that I need to save as an STL file but every time I try to save it I get a message that says something like 'there are too many triangles for the file to be saved safely, please lower the resolution.' I changed the display resolution, but it does not affect the file resolution when saving, any help will be greatly appreciated.

Thanks,

Juan
