Hello everyone, I am really happy to learn the existence of ShapeWays. Everyone is unique and artistically talented. This is totally different than the Mechanical engineering world that I came from. I wish to share my design experience with everyone. My area of focus will be designing inseparatable assemblies -- moveable interconnected parts printed together in single process. Feel free to leave me a message at the Sunny Factory, or the "tiny car with moving wheels and opening doors" model. The car models are also described on blog.objet.com David Sun
