Abstract This paper describes the conceptual design of a portable Solid Freeform Fabrication (SFF) system. The work is based on previous concepts of modeling systems [Manzur et. al., 1997], [Bzymek et al., 1996], [Lotko et. al., 1998] and research in which a desk-top SFF system was developed [Manzur et. al., 1997], [Bzymek, Manzur et al., 1998], [Bzymek, Theis et al., 1998]. Such a system allowed the rendering of parts of 80% to 90% density. The optimized laser path programming [Bzymek, Shaw and Marks, 1998] and diode laser development [Chen and Roychoudhuri, 1994] added new features to that concept. The newly designed system will be compact and light. It will be equipped with a new powerful diode laser based on the newest technology, and will use new achievements in programming concepts, and a new portable high performance computer. An intelligent CAD program, as well as slicing and laser path control software, will be incorporated in the system. The parts to be rendered will have size and loading limitations. Due to the method of rendering, the points of load applications are limited to certain areas and in certain directions. In conclusion, one can state that the newly designed system will be intelligent in use, light in weight, easily assembled and disassembled, and will be able to produce parts of a limited size, presumably up to 3x5x2 inches, with loads supported in certain directions, areas, and points of the part.
