Most of the lessons in this course are universal for Prusa Slicer, Orca Slicer and Bambu Studio. All three are very simliar under the hood (Orca Slicer is build on Bambu Studio which is build on Prusa Slicer which is build on Slic3r). Every now and then there are some differences, which I point out in the combined videos.

Some lessons, like the explanation of the UI or the practical demonstrations have seperate videos for Prusa Slicer and Orca Slicer. Orca Slicer is used synonymously for Bambu Studio. A few icons in Bambu Studio are a bit different than the ones in Orca Slicer but the overall functionality is almost exactly the same. In those split up lessons it's sufficient to watch only the video about the slicer you use.

I'd also like to encourage you to at least try out both, Prusa Slicer and Orca Slicer. Both offer a few unique functionalities not present in the other. I personally have all three installed and choose the one best fit for the job. Like for examply when I want to paint on fuzzy skin, which only Prusa can do currently or when I want to place brim ears, for which Bambu Studio offers the easiest tool.
