Hi, I’m using 3D Slicer for tooth segmentation and I’ve created an stl model from ct scan (DICOM). I’ve done that using Segment editor module. Can someone tell me which segmentation algorithm is used in slicer to create an stl model from ct scan?

If you mean which algorithms are used for generating closed surface from binary labelmap representation of the segmentation: see implementation here . In short: vtkDiscreteFlyingEdges3D followed by vtkWindowedSincPolyDataFilter , vtkDecimatePro (optional), and vtkPolyDataNormals .
