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.
I use this all the time, real filament saver! For the overwhelming majority of real world use cases, the strength of a part has much more to do with the walls than the interior, so it shouldn’t really be any weaker. Just make sure your walls are thick enough.
That was the sentiment I was getting too. I usually use 4 layers on the walls and top and bottom and most of my prints hold together really well.
