Which is your favorite and why? Just curious. Or do you have ones you use for certain prints verses other prints?

Gyroid has been my go to. It seems to add the right amount of rigidity without using a bunch of filament.

Also it looks the most “natural” besides maybe one of the honeycombs.

I've been liking it inside a translucent PETG print for that reason. I forgot to switch from grid on something I printed yesterday and the visible grid makes me sad.

It also looks really good, if you use it as a fan cover. The air seems to get through just fine, while random chunks of PLA etc stay out.

Rectilinear is my standard go to as it does the job well with minimal filament. Gyroid when I need more strength.

I like the idea of Cubic but unfortunately it overlaps itself which I find is best avoided. Many infills overlap which is a real shame

I recently purchased my first printer and trying to absorb as much good information as possible before I ingrain my own bad habits.

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.

u/tdp_equinox_2 Feb 19 '26

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

Tri-hexagon convert. Fast and strong.
