Hi  
I load several Dicom and use volume rendering to create 3D model.how can I save 3D model as a dicom file or mhd and raw?

Volume rendering is just a visualization mode, it does not create any model, segmentation, or labelmap. This has been discussed before on the forum, see for example: [Save volume rendering as STL file](https://discourse.slicer.org/t/save-volume-rendering-as-stl-file/524/21).

You can save the loaded DICOM volumes as mhd/raw file by using menu: File / Save.

To save as STL, you need to first segment the volume using Segment Editor module. See tutorials [here](https://www.slicer.org/wiki/Documentation/Nightly/Training#Segmentation).
