Nice post on Mathematics and 3D printing!
3D printing is the latest advance in technology, that will possibly revolutionise the world!

Below are some images of some of the mathematical structures he and Carlos Salinas have done using a MakerBot 3D printer. Most of these were first designed by using a software called Mathematica, which has the ability to handle complex surfaces and then create the file necessary to run on the MakerBot Software.
