Default Settings
Here are my results using .2mm Speed Profile, 20% grid infill:
Sliced in PrusaSlicer | Prusa MK3S Print time = 1h31m
Sliced in Bambu Studio | Carbon X1 Print time = 0h42m
However, with some speed tweaks, I can actually get the time down to just 0h24m for the Bambu printer. I've actually printed this way before, and the Benchy comes out with comparable/equal quality to the Prusa printed one.
Here is another example in one of my personal applications. I make a 3D printed mountain mod for Getaway. At .2mm the print time on my Prusa MK3S+ was 14h42m, but that same model with the same print settings on the Carbon X1 is 4h:42m
Another speed test using a 2" x 2" x 2" cube at .2mm 100% infill:
Sliced in PrusaSlicer | Prusa MK3S Print time = 2h16m
Sliced in Bambu Studio | Carbon X1 Print time = 0h51m
