Measuring accuracy of 3D printed objects - your needs

Hello,
I have access to some pretty capable coordinate measuring machine at a local university and I am wondering, what kind of features should I measure? I’ll be measuring printed objects from my custom-made MSLA printer (www.oliver3d.com) and as a complete beginner in metrology, I’m a bit stuck with deciding what to measure. Which parameters matter the most to you when you print functional parts? Dimensions, flatness, roundness, cylindricity, parallelism, perpendicularity, angularity, surface quality, ….? And do you have any ideas on how to best approach measuring the influence of resin shrinkage during long-term UV light exposure? I'll post the results here after I get the measurements done (might take a while due to COVID).

Thanks.

Best regards
Adam

... most valid ist dimensional accuracy -- nearly all of the other aspects depends on.

Surface quality is "nice to have"
