Solved, Thickening Walls, make thin walls thicker

[dana_kelley]

Too thin walls are often eliminated. Resulting in missing models features.

Some slicers have added functionality to resolve this. Ultimaker Cura has such a feature. It allows adding thickness to all walls. Up to ~0.34mm. Enough to make thin walled models to print. I found this feature very helpful for printing thin Rose Pedals, Disney Castle, among other models found on the internet.

Is there a Bambu Slicer feature than does this? If not a simple answer, no will suffice. If however you know of a tool or tools that can do this let me know.

If Bambu Slicer can do this, how is it done?

Hi Dana,

Can you share an example to facilitate understanding?

@dana_kelley

Too thin walls are often eliminated.

This can be addressed in several ways in BambuSlicer (even so, not exactly as in Cura):

1. Changing wall thickness in the slicer quality menu:
   
   
2. Enable the "Thin walls feature in the strength settings menu:
   
3. Try the Arachne wall generator in the slicer quality menu:
   

Edit: Further details regarding the Bambu Lab Slicer wall generator:

Detect Thin Walls helps but it is not helping enough. The other settings did not seem to make a difference. By thickening walls by a small amount the rose becomes stronger without taking away from the delicate results.

If every wall is increased by a set amount all walls are printable. The amount use to thicken would be a reasonable thinnest wall value. A wall that is 0.01 mm thick will be 0.35mm. A wall 1mm thick will end up 1.34mm. And so on. The Cura feature simply makes all walls thicker.

Your help led me to the settings required to resolve this. See image.

Under Quality selecting Archane, Minimum Wall Thickness 85% or greater, and Minimum Feature Size set to 5%.

This thickens walls that are too thin to print.

I think there should be a simpler setting, called “Expand all Walls to Minimum Wall Thickness”.

Actually, Arachne doesn’t thicken walls but instead allows to print features that are thinner than the configured line width. It achieves that by allowing variable line width within a range around the configured width. And for very thin features, it is even able to print a single line instead of two outer walls.
That way it allows to print features less than half the width of what classic mode can print.

The feature you asked for is available too in BambuStudio and Orca Slicer. You can find it in the Process settings, tab “Quality”, section “Precision” and is called “X-Y contour compensation”.

But I think, the solution you found is much better, because Arachne prints the model as designed and doesn’t need to make everything chunkier.

I have a Disney Castle Model where some balusters and other small features are missing. Using X-Y contour compensation looks to fix these issues. Both methods have there purpose. The rose works well with the previous. Castle with the compensation. Some castle balusters would not print, same for spires. Using compensation approach to add 0.34mm resolved this issue. Now all features are printable.
