Abstract

A system including: a container for holding a photosensitive medium adapted to change states upon exposure to a light source; an optical imaging system, configured to move above the container holding the photosensitive medium, and having the light source; and a control system configured to: slice a digital model of a three-dimensional object into a slice having a cross section; generate a build cross section by filling a two-dimensional image with one or more copies of the cross section; add to the build cross section a conformal lattice to fill space in the build cross section around the one or more copies of the cross section; and control movement of the optical imaging system above the container to cure a portion of the photosensitive medium corresponding to the build cross section to produce a layer of a three-dimensional object.
