Open Design is a catch all term for various on and off line design and making activities. It can be used to describe a type of design process that allows for (is open to) the participation of anybody (novice or professional) in the collaborative development of something. As well as this, it can be the distribution and unrestricted use of design blueprints and documentation for the use by others. In this paper, the authors highlight various aspects of open and collaborative design and argue for the use of new terms that address what is open and what is not. A range of design projects and online platforms that have open attributes are then explored, whereby these terms are applied. In terms of design, the focus is specifically on the design of physical things rather than graphical, software or systems design.
