Open design is the development of physical products, machines and systems through use of publicly shared design information. Open design involves the making of both free and open-source software (FOSS) as well as open-source hardware. The process is generally facilitated by the Internet and often performed without monetary compensation. The goals and philosophy are identical to that of the open-source movement, but are implemented for the development of physical products rather than software. Open design is a form of co-creation, where the final product is designed by the users, rather than an external stakeholder such as a private company.
Sharing of manufacturing information can be traced back to the 18th and 19th century. Aggressive patenting put an end to that period of extensive knowledge sharing. More recently, principles of open design have been related to the free software and open source movements. In 1997 Eric S. Raymond, Tim O'Reilly and Larry Augustin established "open source" as an alternative expression to "free software," and in 1997 Bruce Perens published the Open Source Definition. In late 1998, Dr. Sepehr Kiani (a PhD in mechanical engineering from MIT) realized that designers could benefit from open source policies, and in early 1999 he convinced Dr. Ryan Vallance and Dr. Samir Nayfeh of the potential benefits of open design in machine design applications. Together they established the Open Design Foundation (ODF) as a non-profit corporation, and set out to develop an Open Design Definition.
The idea of open design was taken up, either simultaneously or subsequently, by several other groups and individuals. The principles of open design are closely similar to those of open-source hardware design, which emerged in March 1998 when Reinoud Lamberts of the Delft University of Technology proposed on his “Open Design Circuits” website the creation of a hardware design community in the spirit of free software.
