The main cause of warping is inadequate supports and/or unfortunate angles you place the part with. Remember you have both gravity and separation force pulling on the part each cycle, unlike with FDM. Align the bed, clean it thoroughly with alcohol before printing and increase base exposure. Make sure there is no debris in the vat. It'll stick. All printer resins are variation of acrylic and you have to design your parts with material limitations considered. However there's a range of premium resins for performance prints, look into Henkel Loctite or BASF offerings. We use BASF RG 35 and RG 9400 for small volume production parts. Also, make sure you do not overexpose: print an exposure target for any new resin to zero out the settings. Supports are certainly unavoidable but are largely a skill issue. After hundreds of prints it takes me minutes to depanel very elaborate designs.
