3D segmented model having problems when printed

[CCSV]

Hi!

I'm using the sample data (CTACardio), of Slicer 3D, to the segmentation of the left lung for 3D printing. I used the LevelTracingEffect and PaintEffect tools to segment the lung, slice by slice. The Model Maker module was used to create the .STL archive.
For smoothing the 3D model I used the methodolgy described here (Slicer3D, Blender and Meshmixer). I used the modes surface and shell, at the UP 3D Printer for print. Seems that the printer did not correctly recognize the model because some portions that is normally printed with a support collumn were printed without it, this absence causes the deformation of the model.

Does anybody know what is happening?
Is it because the methodology do not works with lung? I do not use the registration, is it some relation with the model deformation?

Thanks for all!

Regards and best wishes!

Could you please post a picture or pictures of what are you are trying to do? Are you trying to print the airways or the lung itself?

Hi Mr. Mike!
Thanks for the reply. Sorry for my lack of contact, I was traveling.
Unfortunately, I do not have images. As I told, I've done the segmentation of the lung structure. I considered the lung as a solid figure, nothing inside it (no alveolus or the rest of internal structure). For my tests I just need the lung's shape.

Thanks!
