Modifier modifies suboptimal!

This is a question or a request to the Bambu team to optimize the modifier.

I have an object with 2 walls and 15% infill and I want to insert a modifier cube with 7 walls and 25% infill in a sensitive place. This is generated, but extremely sharply demarcated.

If you take the procedure to the extreme and align the modifier exactly on the outside line (of the part to be reinforced), the opposite of the desired effect happens - the part becomes extremely unstable.

Unfortunately, Cura solves this better. Here the elements to be modified are only added where they are missing and not completely replaced.

I would be happy to receive a suggestion as to how I could solve this problem.

Thank you in advance

I am not a BL team member, but I also moved from Cura to BL Studio and missed the same feature.
I overcome the issue by designing the model as a set of part(s).
Afterwards, I can define distinct printing settings for each part and change the type in the slicer to achieve a goal.
You may also try exposing the software gap in the BL Studio Git page to increase the chances of it being addressed in upcoming releases.

good idea - yes it would be that easy

Unfortunately it doesn’t work either, but thanks anyway

I ran into the same problem. It seems that if you change the wall count in the modifier it will do exactly what you see. Try making the wall count the same as the main model. Re-slice and see what happens.

Leider immer mit dem selben negativen ergebnis

Ich hoffe auf eine Anpassung seitens BambuLab

Did you try arachne? It sometimes generates entirely different routes.

yes, unfortunately it doesn’t work either

Maybe I didnt get your problem. Sorry.
In my case it works:

Silicing without spliting:

Two parts slicing:

Unfortunately not!

Here is exactly the same problem - please look closely. The two walls run around the two parts. The second part with the 4 walls is printed separately. This is exactly what you can see in my pictures above.

Please compare it with my picture of “Cura”, here you can see how it should look optimally.

There is also no annoying seam here.

Nevertheless, thank you very much for trying it out.

Can we put modifiers inside modifiers to modify modifiers? lol

Don’t change any wall settings- instead increase infil type, percent etc. I believe this will get rid of those lines

Hello,

Thank you very much for the information about the infill, I found that out when I tried it out.
I’m just surprised that I’m apparently the only one who notices the suboptimal processing of this reinforcement. You also have to admit that it’s not a pretty solution. :face_with_raised_eyebrow:

I couldn’t find a method to achieve identical results to Cura’s.
The most similar using the split and change type to modifier:

Even so, I am unsure if it prints well and takes too much time.

That looks very good, how exactly did you do that in BambuStudio?

I got the idea from your shared image from Cura, as it shows the outer wall twice.

During the design phase, you need to create a new part (the modifier). Instead of completely duplicating the region where the mod is required, you may offset the boundaries in the interior direction with a distance of one outer wall and two internal walls (based on your design).
This makes the modifier smaller enough not to affect the settings in the wall region of the original part.

Afterwards, in Bambu studio:

  • split into objects;
  • change the type of the new part to modifier;
  • Define the print settings for the modifier region.

Arachne was the only change in the Bambu Studio default settings, as it helps with variable wall thickness. You may check which method performs better.

Maybe it is a bit confusing to explain in writing. If so, let me know so I can provide further details and share the example file.

That is a very good idea.
(…and the explanation is brilliant :wink:)

It takes a lot more work to create the objects because they aren’t simple geometric shapes, but you can at least work with them.

Thanks again for the help. :+1:

holy ship there has got to be a better solution to this. thats not cool.

I am also running into this issue as well. I have not found a fix for it yet. Although JayZay’s idea is pretty brilliant. Just adding to these comments so it may get some notice.
