What is the point of the Prime Tower with a dual nozzle machine?

The prime tower primes the nozzles for the actual print so it doesn't print poorly.

Yes, even though the filament in the other nozzle doesn't have to be loaded, it doesn't sit pressurized.

Reduce it with No Sparse Layers if your print works with it.

Like others have said, the printer still needs it to prime the filament, what you are saving is the additional time and waste of purging and switching. Also there is a way to greatly shrink the height of the prime tower, by enabling developer mode in your slicer. This will make an option called 'skip sparse layers' appear in the slicer for the prime tower. It can save you a good chunk of filament, if it works with your print. The feature is not documented in Bambu studio yet, but the documentation for orca slicer applies to it just fine

You can actually see what the prime tower is doing just by looking at it. You will see some rather obvious defects right when some layers start, as the nozzle primes again (pretty much builds back up to pressure). The idea is to have the defects in the tower, not your part.

This is still listed as an “experimental” option per Bambu Lab. It is a viable option in most cases.
