Turning bits into atoms in real-time? It’s as profound as the idea of instantly sharing thoughts across the world would have been to a person just a few decades ago. So how close are we to the dreams of the 21st century, and what does 3D printing have to do with it?
The story begins with manufacturing. Layer-by-layer, additive manufacturing, colloquially still called 3D printing, is a disruptive form of manufacturing that is transforming—in the short term—the spare parts supply chain. Soon enough it will be much more. A San Francisco startup is printing houses—with better construction and for less money per square meter than standard construction today. And if you think it’s all just plastic, think again. They’re printing cars. They’ve been printing jet engines since early 2015.
Around the globe, people are using 3D printing to create all manner of things, even 3D printing food. Instead of carrying slow moving parts across a network of warehouses, these warehouses will just manufacture the parts as needed. 3D printing offers many advantages over traditional manufacturing, like the ability to print hard-to-find machine parts on demand, or print shapes that aren’t found in traditional manufacturing processes.
