Hello, I am a beginner who has recently started using 3D Slicer. I am trying to create a bone model for fatigue analysis in FEM, and I need to separate the cortical and cancellous bone to assign different material properties. Therefore, I need to implement them separately in STL files. Could you please let me know which method I should use for this?
Additionally, can 3D Slicer generate mapping data to assign material properties?
You can use the Segment Editor to define the two regions, export them as models, and then save as STL.
Another option would be to use the Segment Mesher extension and export a single tetrahedral mesh with a separate label field to indicate which elements correspond with which segment.
