<div class=""> </div>
<div class="">I'm struggling with the vtkBooleanOperationPolyDataFilter. First, I'm computing the difference D between two vtkPolyData objects, say A and B (this is D := {A\B}). After that, I want to append the resulting difference D to B, i.e. make the union of these two meshes. Therefore, I'm using the vtkAppendPolyData filter. However, the final result is not manifold (which is necessary in order to print the mesh). I also tried the vtkBooleanOperationPolyDataFilter with the union operation but the problem still remains - the final result is not manifold and therefore not printable. How can I append these two meshes so that these are manifold and thus watertight (and printable)?</div>
<div class=""><p class=""><span style="" class="">Any help would be appreciated. Thanks!</span></p>

<div class="">Best regards</div>
