Issue with multiple color print

Bambu Lab X1 Series General discussions

Hi,

I am trying to print this model. I’ve colored it with bambu studio and when I preview the model, it’s all good and the colors are separate. No “leaking”.
But when I print, I can see the different color inside the leg of the model before the new part with the different color is printed.
I’ve tried making the number of loop walls higher but that didn’t help.
Any tips?

Re-paint the white part using the “Height Range” tool.
I’m guessing that since this isn’t a purge issue, that model is Red & you didn’t get the White 100% for this part…so the inside or infill is being printed in Red.

Thank you. I’ll give this a try.

Not exactly sure what I am looking at precisely. Does the red part extend downwards in other areas of the model? Do you have purge into infill activated?

Hi,

Yes, the red extends a little in the back. This is like a skirt.
I don’t have the purge into infill activated

Shame, that would have been an easy fix.

I can see two routes in which this bleeding could happen. Both should be visible already in the slicer.

  1. In the past, I did have cases where the purge volume multiplier was set to 0 without me doing anything. So just before slicing, it may pay to double check your purge volumes.
  2. A second item is the anchoring of the filament. While this occurs mainly in-plane, some z-anchoring is usually also happening in the infill across a few layers. To better counteract this, there are a number of things I can think of (the second one of which I have done in the past).
    a) The easy method is to increase the number of walls of the model to make the white more opaque. You’ll probably need 2 more walls. I did not try this myself as my coloring was on models prone to edge curling.
    b) The more rudimentary method, which does not require more filament, is to use the sphere painting tool to paint the affected white area … white. Sounds a bit weird. But if you do this, then your white colour definition will have depth in that area. The sphere is a bit tricky to use though as you may inadvertently paint some red surface white again. Just re-color those with the surface paint tool(s) again.
