Self-repairing pipes. Printed organs. Bulletproof t-shirts. Seriously?
To anyone who hasn’t seen it demonstrated, 3-D printing sounds futuristic—like the meals that materialized in the Jetsons’ oven at the touch of a keypad. But the technology is quite straightforward: It is a small evolutionary step from spraying toner on paper to putting down layers of something more substantial (such as plastic resin) until the layers add up to an object. And yet, by enabling a machine to produce objects of any shape, on the spot and as needed, 3-D printing really is ushering in a new era.
What it will be like to live in a 3D-printed world? Imagine the effect of these five trends:
1. Localized Production For Consumer And Industrial Goods: Biz Stone, Twitter’s co-founder, recently predicted that Nike could be a pure software company in ten years. If this happens, it will be thanks to 3D printing production.
2. Custom Production Materials: The ability to customize the materials used for production—even printing living tissue—will be truly transformative. Doctors are already using 3d printing to create knee replacements customized for each patient.
3. Nano-Printing: The picture above is of a 3D-printed lithium-ion battery, created by Jennifer Lewis and her team at Harvard University. It works like a normal battery, except that this battery is the size of a single grain of sand! Batteries like these may be used to power miniature medical devices, compact electronics or even tiny robots. You’ve heard about the amazing advances in nanotechnology – the fabrication of incredibly small particles down to atoms and molecules? Well, 3D nano-printing allows for rapid prototyping of micro and nano structures.
4. Goal-Directed Design: 3D printing allows for almost unlimited complexity in geometry and materials – so much so that humans become the limiting factor in taking full advantage of the possibilities. But what if a computer could automatically generate hundreds upon hundreds of variations of a design until it solves a specific problem? This is the purpose of goal-directed design. Currently, computer-aided design (CAD) tools are used to manually create, document and analyze designs.
5. 4D Printing: By now you can see where 3D printing will take us. But are you ready for 4D printing? With this new technology, you print a 3D object that at some future point can automatically self-assemble or change shape when confronted with a change in its environment, such as temperature or moisture. This is the fourth dimension. This technology is being pioneered by Skylar Tibbits at MIT, and it has wide-ranging implications for consumers and industries.
As applications of the technology expand and prices drop, the first big implication is that more goods will be manufactured at or close to their point of purchase or consumption. This might even mean household-level production of some things. (You’ll pay for raw materials and the IP—the software files for any designs you can’t find free on the web.) Short of that, many goods that have relied on the scale efficiencies of large, centralized plants will be produced locally. Even if the per-unit production cost is higher, it will be more than offset by the elimination of shipping and of buffer inventories. Whereas cars today are made by just a few hundred factories around the world, they might one day be made in every metropolitan area. Parts could be made at dealerships and repair shops, and assembly plants could eliminate the need for supply chain management by making components as needed.
Another implication is that goods will be infinitely more customized, because altering them won’t require retooling, only tweaking the instructions in the software. Creativity in meeting individuals’ needs will come to the fore, just as quality control did in the age of rolling out sameness.
These first-order implications will cause businesses all along the supply, manufacturing, and retailing chains to rethink their strategies and operations. And a second-order implication will have even greater impact. As 3-D printing takes hold, the factors that have made China the workshop of the world will lose much of their force.
China won’t be a loser in the new era, but it will have to give up on being the world’s manufacturing powerhouse.
China has grabbed outsourced-manufacturing contracts from every mature economy by pushing the mass-manufacturing model to its limit. It not only aggregates enough demand to create unprecedented efficiencies of scale but also minimizes a key cost: labor. Chinese government interventions have been pro-producer at every turn, favoring the growth of the country’s manufacturers over the purchasing power and living standards of its consumers.
Under a model of widely distributed, highly flexible, small-scale manufacturing, these daunting advantages become liabilities. No workforce can be paid little enough to make up for the cost of shipping across oceans. And few managers raised in a pro-producer climate have the consumer instincts to compete on customization.
It seems that the United States and other Western countries, almost in spite of themselves, will pull off the old judo technique of exploiting a competitor’s lack of balance and making its own massive weight instrumental in its fall.
China won’t be a loser in the new era; like every nation, it will have a domestic market to serve on a local basis, and its domestic market is huge. And not all products lend themselves to 3-D printing. But China will have to give up on being the mass-manufacturing powerhouse of the world. The strategy that has given it such political heft won’t serve it in the future.
The great transfer of wealth and jobs to the East over the past two decades may have seemed a decisive tipping point. But this new technology will change again how the world leans.
