Square Foot Manufacturing: a new production concept for micro manufacturing

Today a large number of microstructures are already employed as separate components or as constituents of larger modules in a broad spectrum of production in medical technology, optics, biotechnology, mechatronics, fluidics, (micro)-forming and tool construction. Current research activities are directed towards the downscaling of manufacturing procedures or the formation of complex process chains for the manufacture of micro workpieces. The Square Foot Manufacturing concept represents one approach aimed at achieving significant technical, economic and ecological developments in the production of microstructures by means of machining techniques that can be applied to a spectrum of materials as broad as possible. This fabrication concept representing a refinement of existing desktop manufacturing concepts is currently being developed at the Institute of Production Engineering of Helmut-Schmidt-University/University of the Federal Armed Forces Hamburg. This paper is intended to provide an overview of the theoretical concept and the current state of its technical implementation.
