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.
