3D printing has grown in sophistication since the late 1970s; TED Fellow Skylar Tibbits is shaping the next development, which he calls 4D printing, where the fourth dimension is time. This emerging technology will allow us to print objects that then reshape themselves or self-assemble over time. Think: a printed cube that folds before your eyes...

It's a big concept at early stages; Tibbits shows us three in-the-lab projects that hint at what a self-assembling future mi...

What if we could harness the ocean's movement to protect coastal communities from rising sea levels? Designer and TED Fellow Skylar Tibbits shows how his lab is creating a dynamic, adaptable system of underwater structures that uses energy from ocean waves to accumulate sand and restore eroding shorelines -- working with the forces of nature to ...
