3D Printing used for Tim Burton Movie!

I read this article that I thought was very interesting. It's about how 3D printing and prototypes were used to create the ambiance and storyline settings of Tim Burton's award winning movie Coraline!

Quote:

3D printers quickly transformed CAD drawings into precise models, which could be handled almost immediately. The models were also printed simultaneously in multiple materials, each with different mechanical and physical properties. Photopolymer materials were jetted in ultra-thin layers, allowing immediate curing with UV. The technology was key to the characterization in the movie, as the hundred of models were printed specifically with individual facial expressions that were exchanged on puppet characters to create the illusion of all manner of actions and emotions.

Not environmentally friendly.
