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.

Two hot ends Pros: Most robust No retraction or filament waste Cons: Alignment issues. Reduced travel Dragging nozzle
Dual filament hot end(taichi style) Pros: Easy to mount No offsets Cons: Jamming? Long retraction
Y splitter Pros: easy to mount No offset Compatible with any hot end Cons jamming Super long retraction

2 is mixing hotends. What you describe is 3 (y-splitter with the splitting integrated into the heat sink). They suffer basically the same issues like an "external" y-splitter. You can get them to work but changing materials requires you to do all of the painful setup/calibration once more.

That they don't have oozing issues is correct but I never mentioned this in the first place.

The main issue with 2 (mixing) is cooking the filament and slicers aren't great at this (operational challenge). There are more pro and cons but I think in the end it boils down to two applications: 1. cheap to integrate. 2. While they are advertised as mixing hotend the result is on pair with dual color/extrusion filament.

No offense, but I made the list and didn't include mixing hot ends.
