I have an Elegoo Saturn Mono resin printer.
If I make a 3D model that has a "sacrificial layer" on the bottom, and I place it flat on the bed, will the area in contact with e bed automatically be exposed as a bottom layer with a longer exposure time, or is this something that I will need to do manually?
I'm using Chitubox and an Elegoo Saturn for the printing, and Blender to make the models. I have them all set to the vanilla settings\factory defaults, and am not using any customer setting.
My thinking is that if I have a large object to print that is going to have a flat base, such as a slab of rock for scenery, rather than using lots of heavy supports I could simply add extra material on the bottom of the object, a couple of mm thick, and then sand the entire thing flat using a belt sander and high grit paper to get back down to the material that I actually want.
