I'm currently working on a project for 3D printing that involves a bunch of subdivision and multiple parts, and for those who are familiar with 3D printing, usually a solid, single volume mesh is required to avoid issues with printing. I figured using boolean modifiers would work best, but I ran in to some problems.
When using union, my mesh does not properly form into a new, single volume because of edges that are similar
Offending Edges (Second set hasn't been subdivided since applying boolean applies all modifiers from the target)
What happens
I can create the result I need by moving one set of offending vertices, but then the clean edge I needed is destroyed in the process
I can't join the parts together manually because presubdivide, the subdivision modifier obliterates the edges/shapes I want (yall know how it goes with edge creases)
This happens multiple times throughout the rest of the parts. Is there any way to circumvent this issue, or is the only way to fix it is to manually fix any issues afterwards? I'm fine with doing the manual work (I'd rather not risk a print messing up, as this is going to be a massive multiple piece print so failed prints would be costly), but just wanted to see if anyone knows a workaround.
