I am trying to slice an object with a triangle recess in it on both sides, so one of them will be an overhang. an overhang like thiss should print by bridging, which is what it normaly does. But when i paint it with a different color from the rest of the object, it just refuses to bridge and instead goes around the perimeter of the shape, printing on air. I am very confused as to why it behaves like that and if you know some solutions tell me
Pretty sure I found a decent solution. Bambu definitely has an issue in their slicing logic when changing color on a bridge. This needs to be fixed as this is a very common use case for the AMS in my opinion. Here is the solution I have found:
-
Create a cube modifier and scale it to cover the area you wish to paint. Adjust the height so that it is about 3 layers high. For me that would be 0.6mm since I am using 0.2mm layer height.
-
Move the modifier so that the bottom face intersects the area you wish to paint. My text is debossed 1mm and the height of the modifier is 0.6mm, so I moved the rectangle to 1.3mm on the world coordinates.
-
In the parts browser on the left side of the slicer, right click the modifier and change the filament to the color you wish to paint your deboss.
-
Change the slicer settings for the modifier to be 100% sparse infill. You may need to change the sparse infill type to rectilinear because some types are not compatible with 100% infill.
-
Slice the model, and this should generate a bridge instead of attempting to print walls over the gap.
The Top Image is how the slicer works without changing color. The second two images are with the fix I mentioned above.

Thanks for the fix, I’ve just been painting the whole z axis for a while and just accepted the lines. This is is way cleaner. Although still too janky for bambu standards.
Glad the fix helped. I don’t understand why Bambu hasn’t fixed this yet. I figured they would have addressed it in 2.0, but it still appears to be an issue.
Have you filed the bug against bambu slicer? That would help the correct team to see it.
I have not, but I will definitely go ahead and report the bug. Where is the best place to report it?
I would try here to start with
I’ve never done it myself so there might be other places too
Look to see if the issue has already been reported. If so, add your info. If not, start a new Issue as a bug.
The developers seldom see or respond to bugs reported here in the forum.
