vtkMergeFilter sounds like it will do what you want. If you want more
control, it looks like vtkMergeDataObjectFilter might give you that.

In the future, you could try a quick grep through:

http://www.vtk.org/doc/nightly/html/classes.html

sometimes just the name of a class is enough to clue you on what you'll
need to do.

>(eventually I will need to merge 100's or 1000's of structuredgrids together).

I don't know how well vtkMergeFilter scales, sorry...
Intuitively though, merging a thousand 40x20x20 grids sounds like it
will take a \emph{lot} of resources.

I would be \emph{very} interested to hear how well that scales for you.
