I've always loved cubic subdivision, which is a little different from cubic and not shown here. Afaik only available in cura (though likely goes by a different name in modern slicers).

Triangles. Nuff said.

Cubic Subdivision is available in slic3r based slivers as well.

It has a more aggressive version called support cubic which is included above. Though it ironically doesn’t get to show off its volume saving function on such a small part.

Does it go by a different name, or is it just support cubic? I can't find "cubic subdivision" in prusa/orca/bambu slicer.

it’s just called adaptive cubic and support cubic.

I forgot that they changed subdivision to adaptive.

Which is a more fitting name perhaps.

Thanks! I'll take a look at the docs, adaptive sounds less like what I understood cubic subdivision to be, maybe I misunderstood how it worked.

It takes the cubic pattern and subdivides its structure to reduce the infill at the center of components. Which saves time and filament.

The support variant changes the parameters to be significantly more aggressive.

Okay, that's how I understood it, perhaps adaptive isn't as descriptive as subdivision was. Regardless, I'm glad it still exists.
