  • Shape deposition manufacturing of microscopic ceramic and metallic parts using silicon molds
    Patent number: 6242163
    Abstract: Micro-Mold Shape Deposition Manufacturing (&mgr;-Mold SDM) is a method for fabricating complex, three-dimensional microstructures from layered silicon molds. Silicon wafers are etched using conventional silicon-processing techniques to produce wafers with surface patterns, some of which contain through-etched regions. The wafers are then stacked and bonded together to form a mold, which is filled with part material. In one embodiment, the part material is a ceramic or metallic gelcasting slurry that is poured into the mold and solidified to form a part precursor. The mold is removed, and the precursor is sintered to form the final part. The gelcasting material may also be a polymer or magnetic slurry, in which case sintering is not needed. The mold can also be filled by electroplating a metal into it; if necessary, each layer is filled with metal after being bonded to a previously filled layer.
