Grammy-winning musician Jacob Collier has a name for the feeling that moves through a great piece of music: the wiggle.

3D printing promised to reinvent how we make things, but it’s mostly stuck producing prototypes with a high level of waste. Designer and TED Fellow Schendy Kernizan found a different way — by printing objects directly into a tub of gel. He explains how this technique eliminates the constraints of gravity, pushing the limits of how we can manufacture objects across medicine, fashion, space travel and more.
