ABSTRACT:
A seamless micromechanical object is cast by forming a multilevel mold, filling the mold, and selectively removing the mold with respect to the micromechanical object. The mold can have a first level having a first opening therein, and a second level on the first level, the second level having a second opening therein, the second opening smaller than the first opening. The object may contain a controlled void, for example a micromechanical auger with a void formed therethrough to be used as a capillary to drain off fluids when the auger is in use.
