This came up in one of my groups today. That we could not color bend, or mix 3d printing filaments. I have researched but I am not finding anything talking about Plastic mixing in an extruder.

Why is it that we cannot take say a Diamond hotend, or a hotend with 5+ inputs, and mix any color we want? (assuming all the same type, ABSm, PLA). I think it would be interesting to at the least get a gradient effect on prints.

The best I have seen is natural plastic and a marker system. Or a powder / advanced / out of hobbyist price range process that sprays ink. The only Color Bending I know of is with Recycled plastic that uses multi color. Not quite what I am looking for.

If you clearly observe the geometry of the print it has printed in different colours .the part is designed in such a way that it has the small height gap between the each colour but we cannot seen this gap in one projection plane.. We can print only in direct drive extrusion .by changing the filament of different colours without pausing the print by immediately changing the material . It is printed in single nozzle. The above image clears your doubt.it is designed with different heights.enter image description here
