Regarding the flow media: I think I will do another test, this time only with cork and Soric, and use standard infusion mesh on the whole square.
I've so far found good use for smaller pieces of the cored panels, so the work is not just "test & scrap"

I just did a set of measurements on the thickness and "precision" or evenness of the thickness of the cored panels, and both the Soric and cork have a very even thickness.
The 3D-core is very uniform in thickness as well.
More to follow!
