that depends on what you consider strong.
The Rigid Resin is the most dimensionally stable- but like all the resins, you have to build the parts on rafts so that flat surfaces are not in plane nor perpendicular with the build platform- and then post cure the parts with their support structure attached.
Because Rigid is glass filled- it has a lower shrinkage under the laser than other resins. It is extremely tough, but with less flexural strength than Tough and Durable. It does, however, resist abrasion well because of the glass filler.
( it also looks way better than white resin.)
With the other resins… there are often tricks- such as, Most of them will give the best dimensional accuracy printed at 100 micron thickness. ( the resin has a specific amount of shrinkage when cured… more layers means a greater cumulative shrinkage- which adds greater internal stresses to the part- which are revealed as warpage in post curing )
If surface quality is not that important, I have found that DRAFT resin is dramatically tougher than even tough- though probably much worse in terms of dimensional accuracy.
the support structure on draft resin is a real bear to remove because it just doesn’t break off like the other resins.
