I am no expert and I have used a grand total of 2.types of resin, but my experience is that the fully cured resin is hard and brittle. However it's also pretty tough.
I have been using it to print 10mm scale tanks that are about 40.to.60mm long and end up having pretty thin barrels and nothing has broken yet. I wouldn't deliberately bend them too far, but normal handling seems to be fine. Also all.the tanks below have been done using default exposure settings. The only problems I've really had are when I went to 0.01mm layers and kept the same exposure settings as 0.05mm... really had to.chip them off the print bed, but otherwise everything printed fine
