• President Obama Calls 3D Printing “Revolutionary” in State of the Union
• Details on the 3D Printing Institute from Obama’s SOTU Address

The TED conference has been home to some of the leading ideas about 3D printing. In a recent feature, TED has collected some of the best talks on 3D printing in one place.

At TED, we love sharing stories of 3D printing and its rapidly developing power to make new things possible. TED Fellow Bre Pettis’s Makerbot; the Thingiverse  database allow makers worldwide to share designs for printers; designers printing artificial limbs; artists re-inventing their process — we can’t wait to see what’s next. In honor of 3D printers here are some TED and TEDx talks on understanding this technology.

Here are the top 7 talks.

Lisa Harouni: A primer on 3D printing
So what exactly is 3D printing? Lisa Harouni breaks it down — from machine to design to product. Learn how it all works in this talk from TEDSalon London Spring 2011.

Klaus Stadlmann: The world’s smallest 3D printer
Klaus Stadlmann built the microprinter, the smallest 3D printer in the world. In this talk from TEDxVienna, he demos this tiny machine that could someday make customized hearing aids — or sculptures smaller than a human hair.

Scott Summit: Beautiful artificial limbs
In his work, prosthetics designer Scott Summit noticed that a lot of people had to hack their own artificial limbs — with socks, bubble wrap, even duct tape — to feel comfortable. In this talk from TEDxCambridge, he describes how he turned to 3D printing to create limbs that not only match a person’s body, but their personality as well.

Anthony Atala: Printing a human kidney
The shortage of organ donations is a crisis in healthcare. A possible solution? Printable organs. In this stirring talk from TED2011, Anthony Atala describes his research into the development of an organ-printing 3D printer, and introduces a recipient of the product of a similar technology — a bladder grown by borrowed cells.

Marc Goodman: A vision of crimes in the future
Sometimes, despite the very best intentions, the things we create aren’t used in the ways we thought they would be. In this talk from TEDGlobal 2012, Marc Goodman draws from his experience in law enforcement to show the dark side of technology — what happens when great tools get into the wrong hands. In his talk, he shows a way 3D printing could be used for harm and cautions us to guard against these potentials.

David F. Flanders: Why I have a 3D printer
David F. Flanders is a 3D printing guru and the host of PIF3D, a collective dedicated to hosting “build parties,” during which 3D printing experts help curious outsiders build personal 3D printers. In this talk from TEDxHamburg, he discusses the development of the technology and the implications of its mass use, including 3D printers’ role in recovery relief, architecture, and the office supply closet.

• 3D Printing, Hardware Startups, and Hacks Invade Silicon Valley

In 1954, doctors completed the first kidney transplant procedure. Today, someone dies every 30 seconds from a disease that could be treated through tissue regeneration or organ replacement. What if we could use 3D printing to grow new organs?

Anthony Atala’s state-of-the-art lab grows human organs — from muscles to blood vessels to bladders, and more. At TEDMED, he shows footage of his bio-engineers working with some of its sci-fi gizmos, including an oven-like bioreactor (preheat to 98.6 F) and a machine that 3D prints human tissue.

In the TED video below, Anthony Atala asks, “Can we grow organs instead of transplanting them?” His lab at the Wake Forest Institute for Regenerative Medicine is doing just that — engineering over 30 tissues and whole organs.
