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.
