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
I’ve had my eye on this one ever since I saw it on Reddit years ago: https://www.3dchameleon.com/
It uses switches on the z-axis to kick off the filament change, not sure how it deals with stretched filament.
Interesting, thx for sharing
