3D printers


What if 3D printing was 100x faster?

What we think of as 3D printing, says Joseph DeSimone, is really just 2D printing over and over … slowly. Onstage at TED2015, he unveils a bold new technique — inspired, yes, by Terminator 2 — that’s 25 to 100 times faster, and creates smooth, strong parts. Could it finally help to fulfill the tremendous promise of 3D printing?    

The emergence of “4D printing”

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, or a printed pipe able to sense the need to expand or contract.    

What’s next in 3D printing

Just like his beloved grandfather, Avi Reichental is a maker of things. The difference is, now he can use 3D printers to make almost anything, out of almost any material. Reichental tours us through the possibilities of 3D printing, for everything from printed candy to highly custom sneakers.
