Looks like a great topic to add to the wiki Martin. I used the export to vtk and import into Paraview before when creating a model for 3D printing. But beyond that point I was not involved in processing the data further (the person arranging the 3D printing handled it from here on). I am sure there is more to learn which can then be added to the topic if you start a wiki page for this.
