Fab Lab creator and MIT physicist Neil Gershenfeld offers a look at how personal fabrication is ushering in a revolution in do-it-yourself design and manufacturing. Give ordinary people the right tools, and they will design and build the most extraordinary things. That’s the idea behind Fab Labs, which provide access to prototype tools for personal fabrication—helping citizen inventors turn their dreams into reality. Fab Labs have spread from their start in inner-city Boston to the bottom of Africa and the top of Norway, with projects tackling applications in areas including healthcare, agriculture, housing, and communications.
