America Will Lead the Future of Manufacturing, China Will Follow
In a fantastic opinion piece by technology entrepreneur and academic Vivek Wadhwa, the case is made that America will be the center of manufacturing, not China. This won’t happen through increasing Chinese labor costs or monetary policy, but through American innovation in technology. Specific innovations cited include robotics, AI, 3D printing, and nanotechnology.
Below are Wadhwa’s thoughts on 3D printing:
A type of manufacturing called “additive manufacturing” is now making it possible to cost-effectively “print” products. In conventional manufacturing, parts are produced by humans using power-driven machine tools, such as saws, lathes, milling machines, and drill presses, to physically remove material until you’re left with the shape desired. This is a cumbersome process that becomes more difficult and time-consuming with increasing complexity. In other words, the more complex the product you want to create, the more labor is required and the greater the effort.
In additive manufacturing, parts are produced by melting successive layers of materials based on three-dimensional models — adding materials rather than subtracting them. The ”3D printers” that produce these parts use powered metal, droplets of plastic, and other materials — much like the toner cartridges that go into laser printers. This allows the creation of objects without any sort of tools or fixtures. The process doesn’t produce any waste material, and there is no additional cost for complexity. Just as, thanks to laser printers, a page filled with graphics doesn’t cost much more than one with text (other than the cost of toner), with 3D printers we can print a sophisticated 3D structure for what it would cost to print something simple.
Three-D printers can already create physical mechanical devices, medical implants, jewelry, and even clothing. The cheapest 3D printers, which print rudimentary objects, currently sell for between $500 and $1,000. Soon, we will have printers for this price that can print toys and household goods. By the end of this decade, we will see 3D printers doing the small-scale production of previously labor-intensive crafts and goods. It is entirely conceivable that, in the next decade, manufacturing will again become a local industry and it will be possible to 3D print electronics and use giant 3D printing scaffolds to print entire buildings. Why would we ship raw materials all the way to China and then ship completed products back to the United States when they can be manufactured more cheaply locally, on demand?

3D Printing Will Empower Most Innovative Decade in History – Forbes
Forbes contributor Vivek Wadhwa explains why he believes this will be the most innovative decade in history. Wadhwa is Vice President of Academics and Innovation at Singularity University. Here is his general view:
Why am I so optimistic? Because of the wide assortment of technologies that are advancing at exponential rates and converging. They are enabling small teams to do what was once only possible for governments and large corporations. These exponential technologies will help us solve many of humanity’s grand challenges, including energy, education, water, food, and health.
Among the technologies he cites as game changing this decade, 3D printing has a main feature:
In an emerging field called digital manufacturing, 3D printers enable the production of physical mechanical devices, medical implants, jewelry, and even clothing. These printers use something like a toothpaste tube of plastic or other material held vertically in an X-Y plotter that squirts out thin layers of tiny dots of material that build up, layer by layer, to produce a 3D replica of the computer-generated design. The cheapest 3D printers, which print rudimentary objects, currently sell for between $500 and $1000. Soon, we will have printers for this price that can print toys and household goods. Within this decade, we will see 3D printers doing the small-scale production of previously labor-intensive crafts and goods. In the next decade, we can expect local manufacture of the majority of goods; 3D printing of buildings and electronics; and the rise of a creative class empowered by digital making.
Other technologies Wadhwa mentions include genome sequencing, nanotechnology, micro-electrical-mechanical systems, and artificial intelligence.
