Claim 14:
15. The method of claim 9 wherein generating the base layers includes:
(a) operating the vertical positioner to position the plate upper surface or cured resin upper surface at a distance D below the build plane, the distance D equals at least two times t, t equals a single slice thickness;
(b) operating the vertical positioner to position the plate upper surface at a distance generally equal to t below the build plane;
(c) operating a planarizing module to reduce a thickness of a layer of uncured resin to a thickness generally equal to t;
(d) operate the imaging system to selectively harden the layer of uncured resin; and
(e) repeat (a)-(d) until ceasing generation of the base layers.
