Yes, adaptive cubic varies the density of the cubic structure to decrease filament usage while supposedly maintaining the same strength as normal cubic. And, in my own experience, gyroid always takes longer to print than adaptive cubic – sometimes it only adds a few minutes, but I’ve seen it add nearly half of the print time again for infill-heavy prints.
Same. Sometimes you want something fast. For things that don't need to be sturdy at all (little display figures and stuff like that) I'll use cubic or even lightning infil
That’s all I use similar strength in every direction low material use and ease of print (it’s waves but no sharp corners so easy on the printer’s acceleration.
3D honeycomb is insanely slow. It takes like double or triple the time and is super stressful on the printer because of very high accelerations.
Pretty much its only use of honeycomb seems to be making the absolute strongest prints in compression strength. 3D honeycomb is slightly better, but it is essentially the master of none. Line and rectilinear have the best surface, cubic and gyroid have the best transverse strength. Triangle has as good of compression strength and transverse strength as honeycomb and better than 3D honeycomb while taking a fraction of the time to print.
Honeycomb is probably one of the worst "popular" infills.
I have to find something to print with that - I don't usually do the slicing, but I'm totally going to use gyroid infill whenever I can. Probably as a feature - like someone else said, make coasters without the top or bottom layer, and use it decoratively. Awesome!
