Cadnano and 4D Printing

Skylar Tibbits is using cadnano in 4D printing, which is the process of 3D printing machines to self-replicate. Tibbits is using cadnano to aid in the self-replicating process so that he can see how a design will fold up after water is added to cause the model to transform.
