acuracy of 3d print

[dlaery]

i have drawn a shape that looks like a bullet. the diameter in my 3d part is 0.320"
my 3d printed part is 0.322" in Z
and in X it is .0315"
in the attached pic Z is top to bottom and X is left to right.
I will have to reprint in different configurations to see what is the most acurate.
is this normal?

Sadly yes. I find calculating shrinkage with resin a proper chore. You'll need to contact your resin vendormanufacturer for shrinkage data.

Contact them, or adjust the scaling for the print, as most slicers these days have settings to compensate for inaccurate parts, be it shrinkage or printer geometry issues.
