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
Y splitter is something that goes in the middle of the Bowden tube to allow two extruders. Its similar to #2 but allows you to use any hot end.
How do you handle long uneven and “streched” filament end after full retraction? Sounds like 2. in hard mode
IDK, thats why I asked.
