A little further investigation here, the last 3 sets of seed material broke of rather easily, it felt about like breaking a tiny piece of egg shell with your finger nail.
Back in Cura I counted how many layers of thin material there were in the second last set, looks like about 50 layers of material that are quite thin( altho it dose gradually get thinner) 50 layers at 100 layers per mm thats a .5mm gap between the thick part of the seed material and the actual object.
I think the desired gap could be very different for pigmented resins.

With this new experience next ill move on to modelling the rest of the dna.
