When Michael Bay releases his re-make of “The Graduate” with a virtual Ms. Robinson, the line, “One word: Plastics!” will be updated to “3d printing.”
Being able to make variable density structural supports takes 3d printing beyond nifty and into this-is-the-way-the-future-is-going-to-work!
Keating uses the example of a palm tree compared to a typical structural column. In a concrete column, the properties of the material are constant, resulting in a very heavy structure. But a palm tree’s trunk varies: denser at the outside and lighter toward the center. As part of his thesis research, he has already made sections of concrete with the same kind of variations of density.
