Hi,

my personnal tought about why solid cores develop cellulite and hollow parts don't or do much less altough the rohacell is the same: Hope someone can chime in and conirm this or prove me wrong : because skins of a solid core are fixed into position (laminated to the solid core) they have nowhere to go when they expand/shrink, the only way to relief this stress is to stretch in between the bridges they are glued the rohacell (this means the cell walls which are cut open by the cnc. cell sizes are very small so the the deformation happens on a small scale in each open cell.


Please help.
Thanks!

I didn't find the right solution from the Internet.
