Interesting! That’s quite a different result than the caliper photos here seen here (which IIRC is off by 3-10%)
That’s white resin, though.
For what it’s worth, i’ve had overcuring issues, filled up holes, etc. with white on Form2 as well:
In case it’s at all helpful to you, here’s the very first part I designed and printed on my Form 1, ShaftTest.zip
Thanks, will give it a spin!
