Distributed manufacturing

Distributed manufacturing also known as distributed production and local manufacturing is a form of decentralized manufacturing practiced by enterprises using a network of geographically dispersed manufacturing facilities that are coordinated using information technology. It can also refer to local manufacture via the historic cottage industry model, or manufacturing that takes place in the homes of consumers.

Enterprise

The primary attribute of distributed manufacturing is the ability to create value at geographically dispersed locations via manufacturing. For example, shipping costs are minimized when products are built geographically close to their intended markets. Also, products manufactured in a number of small facilities distributed over a wide area can be customized with details adapted to individual or regional tastes. Manufacturing components in different physical locations and then managing the supply chain to bring them together for final assembly of a product is also considered a form of distributed manufacturing.[1][2] Digital networks combined with additive manufacturing allow companies a decentralized and geographically independent distributed production (Cloud Producing).[3]

Consumer

Within the maker movement and DIY culture, small scale production by consumers often using peer to peer resources is being referred to as distributed manufacturing. Consumers download digital designs from an open design repository website like Youmagine or Thingiverse and produce a product at home for low costs with an open-source 3-D printer such as the RepRap.[4][5] Distributed manufacturing with distributed generation using solar photovoltaic cells and 3-D printers has been proposed as a means for off-grid rural area residents to manufacture themselves out of poverty.[6]

An example of such an application are spectacles. As Gwamuri et al. point out that while it is "still not yet feasible to print the lenses (the most critical component of the eyeglasses)" and in current prototypes "only the frames and syringe are printed" and that "aesthetics is another challenge" the "primary cost of the glasses could be reduced to about one dollar for a highly customized/individualized design, which could be printed on site in under an hour" (presumably excluding the lenses) and "it seems clear that other products could benefit from the same approach and that distributed manufacturing can assist in sustainable development, particularly in isolated rural regions".[7]

Initial life cycle analysis indicates that distributed production can have a smaller impact on the environment than conventional manufacturing and shipping because of reductions in transportation embodied energy.[8][9] There are now several types of open-source solar-powered 3-D printers,[10] which can be used for production in off grid locations.[11]

Social change

Some[12][13][14] call attention to the conjunction of Commons-based peer production with distributed manufacturing techniques. The self-reinforced fantasy of a system of eternal growth can be overcome with the development of economies of scope, and here, the civil society can play an important role contributing to the raising of the whole productive structure to a higher plateau of more sustainable and customised productivity.[12] Further, it is true that many issues, problems and threats rise due to the large democratisation of the means of production, and especially regarding the physical ones.[12] For instance, the recyclability of advanced nanomaterials is still questioned; weapons manufacturing could become easier; not to mention the implications on counterfeiting[15] and on "intellectual property".[16] It might be maintained that in contrast to the industrial paradigm whose competitive dynamics were about economies of scale, Commons-based peer production and distributed manufacturing could develop economies of scope. While the advantages of scale rest on cheap global transportation, the economies of scope share infrastructure costs (intangible and tangible productive resources), taking advantage of the capabilities of the fabrication tools.[12] And following Neil Gershenfeld[17] in that “some of the least developed parts of the world need some of the most advanced technologies”, Commons-based peer production and distributed manufacturing may offer the necessary tools for thinking globally but act locally in response to certain problems and needs.
