| Abstract Scope |
Metal casting provides a potent approach for the three-dimensional freeform fabrication of metal microcomponents. By combining femtosecond laser micro-machining of glass molds with pressure infiltration, one can overcome limitations of the metal casting process that have hindered its entry into the realm of microtechnology. With this process one can produce combinations of dense metal encased within glass, which can either serve together in microdevices, or can alternatively be used to produce cast metal microparts if the glass mold is selectively dissolved. Dense 3D parts of arbitrary shape, made of silver, copper, gold or their alloys can be made with features of size down to ~1.5 µm, with a potential for production rates that far exceed those of alternative processes that have been developed for the production of dense micron-scale metal parts. |
