From The Economist:
The “fab lab”, as Dr Gershenfeld has nicknamed his invention, is a collection of commercially available machines that, while not yet able to put things together from their component atoms, can, according to its inventor, be used to make just about anything with features bigger than those of a computer chip. Among other tools it includes a laser cutter that makes two-dimensional and three-dimensional structures, a device that uses a computer-controlled knife to carve antennas and flexible electrical connections, a miniature milling machine that manoeuvres a cutting tool in three dimensions to make circuit boards and other precision parts, a set of software for programming cheap computer chips known as microcontrollers, and a jigsaw (a narrow-bladed cutting device, not a picture puzzle). Together, these can machine objects with a precision of a millionth of a metre. The fab lab’s purpose is to endow inventors—particularly those in poor countries who lack a formal education and the resources to implement their ideas—with a set of tools that can translate back-of-the-envelope designs into working prototypes.
And it works.
