ABSTRACT:
In certain exemplary embodiments of the present invention, three-dimensional micro-mechanical devices and/or micro-structures can be made using a production casting process. As part of this process, an intermediate mold can be made from or derived from a precision stack lamination and used to fabricate the devices and/or structures. Further, the micro-devices and/or micro-structures can be fabricated on planar or nonplanar surfaces through use of a series of production casting processes and intermediate molds. The use of precision stack lamination can allow the fabrication of high aspect ratio structures. Moreover, via certain molding and/or casting materials, molds having cavities with protruding undercuts also can be fabricated. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. This abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
