Maybe this is what she was getting at when making the comparison to bone structures, but from seeing how it deforms under load in the video, it seems that to realise its potential for serious structural applications this needs to be bonded between two sheets of material to form a composite structure that works like a 'space frame'.[0]
This would allow the fabrication of large stiff arbitrarily shaped panels to form monocoque structures. I would imagine that you could even replace large parts of the conventional rib and skin structure of an aircraft with this eventually. The trickiest problem will be transmitting loads through panel joints.
