over curing in x,y directions

Hi everyone.
I have a problem and I don't know how to solve it. It seems whatever I do, My projector over cures my parts in the x,y direction. Can anyone help me with it?

can anyone help me, when I print a layer I expect to get something like this :

but what I get is :

The grey parts are a little thinner but they exist, and when I print a part, it causes the model not to be smooth enough.
I'm sure I've calibrated it well and the problem is from projector and I don't know how to solve it.

have you tried reducing the exposure time?

I agree: decrease your exposure time.

Yes I did. But the parts will fall.
