It is established in 2002 and received capital equipment by NSF-USA and IITK While the Grassroots Invention Group is no longer in the Media Lab, The Center for Bits and Atoms consortium is still actively involved in continuing research in areas related to description and fabrication but does not operate or maintain any of the labs worldwide (with the excmobile fab lab). The fab lab concept also grew out of a popular class at MIT (MAS.863) named "How To Make (Almost) Anything". The class is still offered in the fall semesters.

The first city-scale FabFi network, set up in Afghanistan, has remained in place and active for three years under community supervision and with no special maintenance. The network in Kenya, (Based in the University of Nairobi (UoN)) building on that experience, started to experiment with controlling service quality and providing added services for a fee to make the network cost-neutral.

Fab City

Fab City
has been set up to explore innovative ways of creating the city of the future. It focuses on transforming and shaping the way how materials are sourced and used. This transformation should lead to a shift in the urban model from 'PITO to DIDO' that is, 'product-in, trash-out' to, data-in, data-out'. This can eventually transform cities into self-sufficient entities in 2054; in line with the pledge that
