Prusa has a really good feature where after adding supports you can export the file as an STL with the supports. I means if I add supports and the model fails to print properly because I didnt add enough/correct supports then all I have to do is reload the STL with supports and add a few more. Instead of doing ALL the supports all overagain.
Also means I can support a number of models individually then when I know they print correctly all I have to do is fill up the build plate with a number of pre supported models increasing my productivity.
