The first new construction technique for a long time. New materials and new methods. It's going to get very interesting in the next few years.

Impressive stuff...
I've not been impressed anymore than the first time I saw stereolithography in use for F1 prototype testing around 6 years ago - my jaw was on the floor. Digital printing seems a little rough round the edges as a tech to me. This new form you point out above certainly appears an improvement.
