What is Big Think?  

We are Big Idea Hunters…

We live in a time of information abundance, which far too many of us see as information overload. With the sum total of human knowledge, past and present, at our fingertips, we’re faced with a crisis of attention: which ideas should we engage with, and why? Big Think is an evolving roadmap to the best thinking on the planet — the ideas that can help you think flexibly and act decisively in a multivariate world.

A word about Big Ideas and Themes — The architecture of Big Think

Big ideas are lenses for envisioning the future. Every article and video on bigthink.com and on our learning platforms is based on an emerging “big idea” that is significant, widely relevant, and actionable. We’re sifting the noise for the questions and insights that have the power to change all of our lives, for decades to come. For example, reverse-engineering is a big idea in that the concept is increasingly useful across multiple disciplines, from education to nanotechnology.

Themes are the seven broad umbrellas under which we organize the hundreds of big ideas that populate Big Think. They include New World Order, Earth and Beyond, 21st Century Living, Going Mental, Extreme Biology, Power and Influence, and Inventing the Future.

3D Printing: A Coming of Age Story

December 22, 2011, 2:52 PM

What's the Latest Development?

3D printing is taking on an increasingly large role in the manufacturing processes of large American companies like GE. The airplane manufacturer uses a laser to trace out the shape of plane components, such as a fuel injector, "on a bed of cobalt-chrome powder, fusing the powder into solid form to build up the parts one ultrathin layer at a time." Aerospace companies have been at the forefront of the technology because airplanes often need parts with complex geometries that fit in jammed compartments. 

What's the Big Idea?

The future of 3D printing technology is often imagined as a series of individual inventors, all working on their unique projects, afforded an inexpensive prototyping process by 3D printers. But there is a larger, more traditional role for 3D printing: There are already 20,000 parts flying in military and commercial aircraft made by Boeing, and despite how slow the 3D printing process is, major manufacturers increasingly want to use the technology to produce specialty parts not well suited to traditional manufacturing.
