With the Kudo3D Titan 1 printer (that uses a modified version of ProjectLayer), I generally use 4-5 regions currently, generally for:
Attachment layer, just 1 or 2 layers at the beginning for attaching the print to the build plate, usually extremely long cure like 60-120 seconds
Support/Foundation Layer - Area at the base of a print or before the part starts that need to be built harder than normal, but not as long as the attachment layer
Transition layer - Something in-between the support/foundation settings and the normal build speed to reduce artifacts from sudden layer changes
Rest-of-print - Normal (faster settings)
Optional - Some of my parts are hollowed and have a roof that comes in later in the print, so I add in another region where that occurs to slow down and increase the lift due to the increased surface area.
There are a few Titan 1 users who regularly use ProjectLayer to change settings in the middle of a print. In particular, they may find that a given lift height is too big or too small after a few sample layers are printed, an then change it.
Based on popular request, Kudo3D made changes to Projectlayer to support 8 regions (I think the original only supported 4). While I have never personally used all 8, there have been a few users who have asked for more than 8 regions based on changing part surface areas in the prints they are making.
In the longer term, I think a better approach would be for a program to analyze the surface area and density of each region, and then based on some base exposure/lift height/lift speed settings, apply a multiplier based on the surface area and density.
