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.
Apart from the aesthetic and its strength, a major advantage of gyroid that I experienced is that it reduces jerk which leads to less vibrations and noise.
This lightning infill looks like the exact opposite in that regard.
