Assuming you have CT(Volume) data ,

If you are trying to reconstruct a cranial defect there are a number of ways to achieve this in 3D Slicer.  
**One option is**

**Another way of achieving this is described in detail here,**

> If you have a CT image as input then then a workflow like this should work:

**The way you can get your data as STL files can be found here,**
