This new section is dedicated to Open Manufacturing developments, making it easier to identify interests in creating physical objects. This is a smaller subset of our much broader section on Open and Shared Design Communities.
However, this section also includes developments about 'production' and 'making' in general, including topics like the DIY revolution, the digitalization of crafts, and agricultural production.

So, what can we do to prevent instability? The solution isn't to formulate vague contingency plans or return to passive optimism. Obviously, that won't work. No, the solution is to improve our resilience to these systemic shocks through a social and economic transition that follows this simple formula:
* Localize production. * Virtualize everything else.
- John Robb 
"The emergence of commons-based techniques — particularly, of an open innovation platform that can incorporate farmers and local agronomists from around the world into the development and feedback process through networked collaboration platforms—promises the most likely avenue to achieve research oriented toward increased food security in the developing world. It promises a mechanism of development that will not increase the relative weight and control of a small number of commercial firms that specialize in agricultural production. It will instead release the products of innovation into a self-binding commons—one that is institutionally designed to defend itself against appropriation. It promises an iterative collaboration platform that would be able to collect environmental and local feedback in the way that a free software development project collects bug reports—through a continuous process of networked conversation among the user-innovators themselves."
- Yochai Benkler (, p. 22)
"The guaranteed income will, in fact, lead to the revival of "private enterprise." Once the guaranteed income is available, we can anticipate the organization of what I have called "consentives": productive groups formed by individuals who will come together on a voluntary basis simply because they wish to do so. The goods produced by these consentives will not compete with mass-produced goods available from cybernated firms. The consentive will normally produce the "custom-designed" goods that have been vanishing within the present economy. The consentive would sell in competition with firms paying wages, but its prices would normally be lower because it would need to cover only the cost of materials and other required supplies. Wages and salaries would not need to be met out of income, as the consentive members would be receiving a guaranteed income. The consentive would be market-oriented but not market-supported."
- Robert Theobald, The Guaranteed Income, 1966
Karim Lakhani on Communities driving Manufacturers out of the design phase
"for any given company - there are more people outside the company that have smarts about a particular technology or a particular use situation then all the R&D engineers combined. So a community around a product category may have more smart people working on the product then the firm it self. So in the end manufacturers may end up doing what they are supposed to - manufacture - and the design activity might move to the edge and into the community." (http://www.futureofcommunities.com/2007/03/25/communities-driving-manufacturers-out-of-the-design-space/)
Kevin Kelly and Terry Hancock on nearly-free material production
"Material industries are finding that the costs of duplication near zero, so they too will behave like digital copies. Maps just crossed that threshold. Genetics is about to. Gadgets and small appliances (like cell phones) are sliding that way. Pharmaceuticals are already there, but they don't want anyone to know. It costs nothing to make a pill." (http://www.kk.org/thetechnium/archives/2008/01/better_than_fre.php)
Both the capital and marginal cost of making products has trended consistently and rapidly down as manufacturing tools become both cheaper and more versatile, so that the capital cost of an object is increasingly not in the capital equipment required to manufacture it, but in the effort required to design it.
- Terry Hancock 
Steve Bosserman outlines what is most appropriate for local distributed manufacturing
"strong candidates for a locally distributed manufacturing approach include ANYTHING that is agriculturally- based like food, feed, fiber, and biofuel production, much of housing and building construction including the manufacturing of inputs used in that industry, localized electric power generation using non-bio sources like wind, solar, and geothermal, and production / manufacturing of materials, components, and assemblies that use locally sourced raw materials and draw upon open-source, relatively easy to learn, appropriate technologies that can be applied in a wide range of situations-- not just a single product."
Eric von Hippel on Manufacturing around User Innovation Communities
"Threadless has tapped into a fundamental economic shift, a movement away from passive consumerism. One day in the not-too-distant future citizen inventors using computer design programs and three-dimensional printers will exchange physical prototypes in much the same way Nickell and cohorts played Photoshop tennis.
Eventually, Threadless-like communities could form around industries as diverse as semiconductors, auto parts, and toys. Threadless is one of the first firms to systematically mine a community for designs, but everything is moving in this direction.
He foresees research labs and product-design divisions at manufacturing companies being outstripped by an "innovation commons" made up of tinkerers, hackers, and other devout customers freely sharing their ideas. The companies that win will be the ones that listen." (quotes and paraphrased by Inc. )
Frank Piller on User Manufacturing
"User manufacturing is enabled by three main technologies: (1) Easy-to-operate design software that allows users to transfer their ideas into a design. (2) Design repositories where users upload, search, and share designs with other users. This allows a community of loosely connected users to develop a large range of applications. (3) Easy-to-access flexible manufacturing technology. New rapid manufacturing technologies ("fabbing") finally deliver the dream of translating any 3-D data files into physical products -- even in you living room. Combining this technology with recent web technologies can open a radical new way to provide custom products along the entire "long tail" of demand.
User manufacturing builds on the notion that users are not just able to configure a good within the given solution space (mass customization), but also to develop such a solution space by their own and utilize it by producing custom products. As a result, customers are becoming not only co-designers, but also manufacturers, using an infrastructure provided by some specialized companies." (http://mass-customization.blogs.com/mass_customization_open_i/2007/11/webinar-the-nex.html)
Jeff Bezos on User-Manufacturing Everything
"Before long, “user-generated content” won’t refer only to media, but to just about anything: user-generated jeans, user-generated sports cars, user-generated breakfast meals. This is because setting up a company that designs, makes and globally sells physical products could become almost as easy as starting a blog - and the repercussions would be earthshaking. " (http://www.usatoday.com/tech/columnist/kevinmaney/2006-11-21-amazon-user-generated-products_x.htm)
Flexible Manufacturing and the Maker Movement
"Two future forces, one mostly social, one mostly technological, are intersecting to transform how goods, services, and experiences— the “stuff” of our world—will be designed, manufactured, and distributed over the next decade. An emerging do-it-yourself culture of “makers” is boldly voiding warranties to tweak, hack, and customize the products they buy. And what they can’t purchase, they build from scratch. Meanwhile, flexible manufacturing technologies on the horizon will change fabrication from massive and centralized to lightweight and ad hoc. These trends sit atop a platform of grassroots economics—new market structures developing online that embody a shift from stores and sales to communities and connections." (http://iftf.org/node/1766)
