Is there a way to export this point cloud to another program

Yes, of course! The point cloud is the 3D image volume file (usually saved in .nrrd file).

@avarghes23

program (like Meshlab) to generate a mesh and subsequently an STL?

MeshLab and other mesh editors operate on meshes, they cannot load or display volumetric image data.

@avarghes23

Rendering module converts the input image stack to a rendered cloud perfectly and if there was a way that we could generate an STL, i

STL is for storing surface mesh that you generate by segmenting a volume. Surface meshes can be printed using cheap plastic printers.

If you have access to a color voxel printer then you can 3D print volume rendering directly, using images created by SlicerFab extension’s BitmapGenerator module.
