An interesting problem for those who're good at e.g., geometric packing problems and space-filling curves.

I wonder about having an optional fill mode with more of a sphere-packing approach. I.e., instead of layering long threads of filament, what if you put down a bunch of dollop-drops in a checkerboard pattern and then staggered successive layers of dollops to fill the gaps?

Slicers are just starting to add non-planar movement support. https://youtu.be/cbhWni9f980?si=EvwZzAU4c5tZKYH4
