There are a few main reasons why you will likely require supports on your resin 3D printer. The most common reason is that the parts of the model that don’t have a direct connection to the build plate need to be printed as accurately and quickly as possible. Secondly, some parts of the print may be too large to fit completely on the build plate without support. And finally, if your resolution is low enough then supports may be necessary to keep the model from warping or drooping during printing.
