I’ve been using gyroid infil almost exclusively since I first tried it.
I was using cubic before, which was fine, but gyroid seems much sturdier for the same % infil even if it does take a bit more print time.
Also it looks awesome.
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.
