Some time ago I watch Cinema 4D - Easy Welding Seams with Volume Builder (& Fix for Round Surfaces) - YouTube
So, I recreate this in C4D with volume builder, which use SDF. Result is more or less ok. need more experimentation. Earlier I use Blender to emulate volume builder and make some splashes. This work fine. But for more exact model you need something else.
Maybe is possible to use some of free SDF software to make fast “high poly” from … nothing 
It’s interesting workflow. You always can make some changes with sculpting… Here is my result from C4D. I guess that someone will try this in Blender too.
