I noticed that the resin vats are dotted with little dots after a while.
This clouding of the silicon layer is due to the vertical supports because the laser shines on the same area through all the height of the support.
So instead of doing vertical columns braces with diagonal struts, it would be more clever to use an angled 3D lattice.
Moreover, I think that the supports could be made more efficient by making it a real space frame instead of braced columns.
In short : less material, stiffer, and spreading the wear of the vat more evenly.
