> Can i repeat same code of segmentation to add multiple segment in same model

To fuse segments, you can use Logical operators effect.

You can merge segments (boundaries between them is kept) if you use the direct file export tool that has been added recently to the nightly build - see [Save segmentation directly to STL or OBJ files](https://discourse.slicer.org/t/save-segmentation-directly-to-stl-or-obj-files/2428)

You can merge models one by one using Merge Models module.
