How does the printing software handle nonmanifold items, like details, that are enclosed in manifold objects?

here is an example of what i mean:

The cube is fully manifold, though the dome doesn't have a face on the bottom.

It will get rejected. Each shell needs to be manifold and watertight.

At least for this simple of a model, you are not "Required" to boolean the shells together, but it becomes a good idea as the complexity of the model increases

Interestingly, Shapeways accepts such a model and fixes is correctly, see http://shpws.me/4V9u - I don't know what might happen with a more complicated model of consisting of many closed and open shells though.

NetFabb Cloud service also accepts such a model. The service booleans the closed and open shells together quite nicely which gives scope for a more complicated model using the service to join parts in stages.

ah i see,
i already canceled the original order and created a new model though.

its currently awaiting fabrication Very Happy
