The print is soft , the forces pulling the print around when separating from the FTP film are high . The plastic does not always spring back into place . Result = distortion
Imagine that ,in the slicer, your model made of rubber and being pulled upwards by some malign force trying to wreck your day. Orient it so the minimum area is exposed (watch out for suction cups - closed peripheries of print that act one large area) . Support it everywhere with little tri-pods of support ,
Temperature: The resin gets hot when exposed , thick sections will retain the heat and can cause internal stress (force) that can bend the whole print out of shape, so hollow out and use infill where necessary (and don't forget punch vent holes to avoid suction cups) .
Sometimes it is helpful to add sacrificial supports at the modelling stage to ensure long overhanging edges have sufficient support without becoming a mess of slicer supports.
