ABSTRACT
Individuals engage with their own home or portable printers in their everyday routines, largely replacing the need for retail shopping for objects. The scenario is generally 'open' and corporate influence in personal 3D printing is minimal. The peer-to-peer sharing of 3D printer designs allows the technology to feasibly spread without any engagement in consumer markets. The sophistication of mass adopted 3D printer technologies is not as advanced as in other scenarios, principally because innovation occurs through grassroots collaboration rather than industry investment. This scenario involves ubiquitous household desktop printers assembled as a kit or bought fully assembled, or even printed pre-assembled or in parts in a self-replicating process from open source designs. The limitations of this scenario are in foreseeing the ubiquity of personal or home laser sintering or electron-beam melting. In this scenario users engage with designs collaboratively, both reverse engineering existing ones and sharing their creativity with others.
