Claim 13:
14. A method of fabricating a build part using a vibration-assisted stereolithography system, the system comprising (i) a build platform to support a build part during building and (ii) a first linkage system connecting a first vibratory source to a first side of a constrained surface, the method comprising:
moving the build platform supporting the build part to separate a build surface of the build part a distance from the constrained surface to form a gap between the build surface having a gap thickness, wherein the moving is a first direction parallel a first axis;
populating the gap thickness with a resin;
at a first time, directing an electromagnetic energy from a light source through the constrained surface to cure the resin residing in the gap;
at a second time after the first time, applying a separating load along the first axis parallel to the first direction, to the build platform to at least partially separate the build surface from the constrained surface; and
at a third time after the first time, activating the first vibratory source at a 60 Hz sine wave to transmit a vibration through the first linkage system, the vibration filtered by a bias element having a coil spring attached to the first linkage system, the filtered vibration oscillating the constrained surface along the first direction to separate, post-cure, the build surface from the constrained surface.
