Advocating U.S. manufacturing jobs through 3D printing

Michael Heisenberg at Seeking Alpha has an opinion post about the decline of American manufacturing and how to turn the tide. The solution: get the 3D printing industry going in the US. Interestingly, he cites the iPhone as an example of how America lost the battle. (As he talks about the iPhone, I suggest you read my manifesto Death to centralized manufacturing, long live 3D printing--or why Apple should venture into printers.)
Obama's leapfrog is to turn America into the Global leader in local production by investing heavily in 3D printing and the maker class. In the same way that the Chinese government invested in glass factories that ultimately won business for iPhone production, America can start manufacturing again by setting up centers of low cost, mass customized production via 3D printing and this should be done locally. America's innovative class is already leading in 3D printing with the Maker Movement, making waves and gathering a following. 
What is missing is ubiquity and lower costs. As a number of commenters discussed on Fred Wilson's AVC blog, cost and ubiquity still stand in the way of an explosion in 3D printing but it will come and when it does, America should want to be at the forefront because 3D printing can disrupt the current global supply chain. Yes, disrupt the current global supply chain. 
Already, private companies are leading the way, 3D Systems (Nasdaq: DDD, Objet (in IPO process) and Shapeways are driving the costs of 3D printing lower (ironically Objet (Israel) and Shapeways (great prezi)(Netherlands) are both non-US companies) and making mass customization cheaper and more accessible. However, if you want to leapfrog, you need to go all-in. By subsidizing and encouraging the building of local infrastructure, retraining middle class manufacturing to start and operate 3D printing facilities and by building global/local supply chains by investing massively in 3D printing facilities, Obama can start altering the global supply chain dynamics.

3D printing and construction



3D printing is traditionally a tabletop enterprise: printed products are about a few inches big in each direction. However, another application for 3D printing is emerging that's quite a step up from, say, replacing your missing LEGO bricks: construction.

Txchnologist has a report about a concrete-excreting printer that builds houses. (beware, this website is a pr/marketing front for GE, so if you get a sudden urge to buy a jet engine you know why)
Khoshnevis calls his technique “Contour Crafting” and it operates on roughly the same principle as consumer 3D printers like MakerBot’s Thing-O-Matic. His robot pours out a trail of viscous concrete while tracing along the footprint of a wall. As the nozzle sweeps back and forth, the layers rapidly build, with the lower ones hardening enough to support the increasing weight. Its speed puts construction workers to shame. “We are talking about a technology that can build a square foot of wall in less than 20 seconds,” Khoshnevis says. At that rate, Contour Crafting can put together a whole room in just an hour.
Size is now the only thing holding back the technology. “We have a machine that can build a structure about 23 feet long, about 7 feet high and about 15 feet wide at this point,” says Khoshnevis. He estimates that a full-scale printer would break down into three pieces and be small enough to fit onto a flatbed truck. All construction would happen on site. First, a designer would bring a digital blueprint for the house on a thumb drive and plug it into the printer while workers loaded it with concrete. Once the printer was activated, humans would play a supporting role, laying out supplies for the robotic gripper arm and preparing fresh batches of concrete. Humans would also install the windows and doors, since the task is so easy it’s not worth automating, Khoshnevis previously said.
Some modern skyscrapers are already built using a semi-automated process where the central concrete core is continually built up, day and night; however that method doesn't allow for any customizations like the one above.

Although fully automated, fully customizable construction is still a few steps away, a Chinese company called China Broad Group built a 30-story building in 15 days using mostly prefabricated materials (see video up top). The main benefits are not only rapid construction, but also a decreased use of materials and operational energy:
We have been closely tracking China's Broad Group and their prefabricated factory mass produced 'Can be Built' skyscraper technology. Six months ago they had earthquake certified a scale model of their 30 story building. now they have built an actual 30 story building in 15 days at the end of 2011.
This is one of the key technologies to watch for the next decade or two. The reason is the construction methods use far less cement and are more energy efficient. They will also enable faster urbanization of the developing world (not just China.) With state backing Broad Group will have this technology in use for more high rise commercial construction by 2020. This is part of the mundane singularity of technologies that mostly exist now and can high impact on the world. The buildings are five times more energy efficient in operation and use about 6 times less cement.

3D printing, Anti-consumerism, Thomas Jefferson, Occupy Wall Street: it's what binds the USA together

Dylan Tweney at VentureBeat.com has something to say about the intersection between 3D printing, the American pioneering spirit and current countermovements in contemporary culture and politics.
“We have a consumer product that’s anti-consumerist,” MakerBot Industries founder Bre Pettis told me at CES 2012, where I captured the short video below. “When you get a MakerBot, you have an alternative to buying things. You can download them … or you can design something and make it custom yourself.”
(...) I’m convinced that the people who have embraced the DIY movement have tapped into the core of what makes the United States great: Self-reliance, experimentation, innovation and a non-dogmatic reverence for facts. Over the decades, innovators tinkering in metaphorical (or literal) garages have played important roles in the development of electricity, radio, computers and, now, the internet economy.
DIY, or at least a willingness to take initiative for doing things on one’s own, outside the usual structures, has also played a role in political life, with grassroots organizations like MoveOn.org and loosely organized movements like the Tea Party and Occupy Wall Street drawing much of their strength from people’s iconoclasm and sense of self-sufficiency.
