Hello
When I import my obj/stl in Chitubox it isn’t the same size and orientations.
So in blender
- I put my scene in mm,
- made ctrl A to my model to have a clean 1/1 scale.
- selected « scene scale » in the window export
But 
No success
So, I’m guessing it’s teeny tiny, right?
When exporting, on the right hand panel, it will say Scale Set that to 1000 - it will then have the correct scale in that, or any slicer for that matter. It’s something to do with Blend Units as opposed to actual dimensions.

Yes very very tiny 
So when I export, in the window I scale it 1000 time?
When exporting, you will see scale value. Don’t scale it in viewport - although, yes, that would work - it’s not the best way to do it.
Just set this scale value in the export panel to 1000.
