The gravity-defying future of manufacturing | Schendy Kernizan

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.Following his story, pulled from a short film he made for TED, Kernizan speaks with Lily James Olds, director of the TED Fellows program, on where this fascination with making things first came from. They talk about what kind of objects Kernizan’s is most excited to build, how he overcomes setbacks, and what keeps him motivated. Hosted on Acast. See acast.com/privacy for more information.

Urging us to slow down in the age of immediate news, Butler shows how a drawing reveals what a headline can't. Hosted on Acast. See acast.com/privacy for more information.
