Hello,

I'm fairly new to 3D printing in general but am an experienced 3D Artist. I got myself an Ender 3 printer w/ PLA filament and have been experimenting with different prints but after watching some videos i noticed people were hollowing their models for resin prints. Though this has me wondering if this is even necessary for PLA filaments that you plan to resin cast later? Bringing the model into a slicer like Cura has a shell/wall thickness option already so is it even necessary to hollow out the model in a 3d modeling software?
