Toooons of waste. 2.5/1 waste/print ratio. wow.

What would be nice would be a way the waste can be used to print something else like a functional part that colors won't matter.
Yeah like during the infill portion of each layer, swap the color. But I can only see that work if each layer is a separate color.
If you have different parts of the same layer, you could jump back and forth to the infill to purge. But you'd need to make sure you have enough inside volume compared to the outside surface area.
Mosaic, the Palette company, have that as a feature in their slicer and I've heard Prusa Slicer was working on it a while back.
Prusa Slicer does have a "Purge to Infill" option that removes a lot of this waste. Unfortunately, Bambu printers are infamous for their poop problems..
Not sure what's the current state of other slicers. but PrusaSlicer has a setting that does exactly that, called 'Wipe object'.
As others have said few slicers support printing a second model as the wipe/purge object, but Stefan from CNC Kitchen happens to be one of the few people on earth that owns a filament recycling setup so these poops might get recycled as well.
That would involve remelting the filament and re-extruding, which can be bad for strength. Maybe you could print the functional print at the same time and use it as the purge tower?
That's not a bad idea if you have a part big enough to print and space on the bed for both. I'm curious how strong the print would be if it's made up of a bunch of partial lines. It would be like multiple failure points per layer. But if the part doesn't need that much strength, it would be convenient.
