I'm thinking of building a new printer and would love to be able to make 2 color prints or dissolvable supports. Does anyone have any experience with this. I see 3 paths.

  1. Two hot ends Pros: Most robust No retraction or filament waste Cons: Alignment issues. Reduced travel Dragging nozzle

  2. Dual filament hot end(taichi style) Pros: Easy to mount No offsets Cons: Jamming? Long retraction

  3. Y splitter Pros: easy to mount No offset Compatible with any hot end Cons jamming Super long retraction

Personally I like the Jubilee tool-changing system, where multiple extruders are mounted on a rack and swapped between as needed. It's what I plan to build at some point

That's a cool way of doing it, but it seems like it would be difficult to align. In my case, I am thinking of doing a belt style printer, so that may be even more difficult to engineer.

They have a method of aligning it using machine vision https://jubilee3d.com/index.php?title=TAMV

The belt part would be a challenge though.
