Oblique Indented or Machined Micro Wedges

Due to the difficulties and limitations inherent to the double-exposure lithographic method of producing molds, other mold production methods were investigated. One such method involved using a very sharp indenting tool, currently a microtome blade, to make serial indentations in to a soft, malleable material to produce the desired negative shape. Once the mold was indented in to the material, currently a flat sheet of wax, liquid polymers could be cast in it and left to cure. Using such a method allows much tighter control over feature body angle, internal angle, spacing, and depth.

For details on the micro-wedge machining and casting process see AdhesiveManufacturing and the ManufacturingPublications page.
