Rational Functions

Everyday Explorations

Skylar Tibbits is the founder of the Self-Assembly Lab at the Massachusetts Institute of Technology's International Design Center. His invention of 4-D printing involves programmable materials that can sense and respond to internal or external stimuli. His research aims to apply principles of self-assembly to construction and manufacturing: for example, a cell phone that can build itself or a chair that self-assembles.

What is self-assembly?

How are 3-D printing and 4-D printing similar? How are they different?
