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.
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.
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.
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.
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.
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.
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.
