Hi everyone,
I’m having an issue with a print where the black filament I’m using for infill is showing through the white walls. The part is only 4mm thick overall, and due to the geometry, the black section occurs close to the top of the print. This limits how many walls I can add to mask the black filament.
I’ve already tried increasing the wall thickness, but the black infill is still visible. Is there a way in the slicer to prohibit a specific filament from being used as infill, or any other techniques to prevent this issue?
Any advice or suggestions would be greatly appreciated!
Thanks in advance!
White filament and most filaments have a decent amount of translucency and you need at least 5 layers of 0.2mm or more with white and other bright filaments.
You would need to share photos of the printed model and even a 3mf to have anyone provide suitable specific help as your description is general.
This might mean you simply can solve it, without more to go on you can only get generic responses.
- Increase flushing (probably unrelated)
- Increase shells/walks (sounds like you have tried)
- Change order the filaments print (may not play a roll)
Hi Malc,
Sorry it was late and I forgot to add any useful files, I have attached the 3mf file and some images. I.m thinking of printing the window frames separate.
Ive not cleaned off all the supports as this was a first draft print.

Have you thought about making the whole part white and just painting the windows black in Bambu Studio? It would take more filament due to the filament swaps but it would stop the bleed through. If the top, bottom and sides aren’t going to show on the finished model you can use the paint by layers to just color the layers where the windows are and that will give you more white layers on the outside to prevent the black from showing through. That would only take two color swaps. Just some thoughts…

Did you ‘paint’ the windows (using the paint tool)?
I will check the 3mf shortly to confirm, but that might be the issue.
If the windows are their own part with the walls a separate piece of geometry, export both from your cad software as different models and then you can import both into the slicer at the same time and agree they are the same part.
This will let you select the doors in the Bambu Studio from the objects view of the prepare tab and select it as black, make the walls white.
When you paint a model (assuming you have) it doesn’t just select the surfaces, it aims to have a depth to the paint so it can be seen, ironically the opposite of what you want.

Thanks both, you were correct. I initially used the paint feature. As you suggested I modelled the windows and sill and head detailing as there own parts. Printed perfectly
