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
Filament swap is not really a valid alternative when it comes to something like wanting dissolving supports. It’s only realistic if you want to change the color or material for a fairly large consecutive portion of a print. Otherwise you’re going to have to swap out the filament every layer.
Sharpie hack is also not a valid alternative hehe. These 2 were more like a joke, but for simple designs manual swap works like a charm. Swapping filament every layer would be honest work tho
