If you don’t know what lightning infill is, it was made by Cura and was added to PrusaSclicer.
I chose to print with it since it showed up as a tool tip. Hoping has the same infill strength as Gyroid as it’s suppose to use less filament (estimates is around 5 grams for this part). It was suppose to also save time, but it instead added 10 min.
Lightning does not compete with Gyroid on strength. Lightning is basically designed to be as weak as possible while still supporting the layers above it.
