  • Publication number: 20180029292
    Abstract: A method of forming the body portion of a three-dimensional object (17) from a polymerizable liquid (16) is carried out by a process including advancing a carrier (18) for the object away from a build surface while irradiating a build region between the carrier and build surface in a pattern of advancing and irradiating defined by an operating mode. The body portion has a plurality of contiguous segments, with the irradiating carried out in sequentially presented slices of exposure. Each slice having a pattern that corresponds to a segment of said body portion. Each pattern includes regions of greater irradiation and regions of lesser irradiation (e.g., within the perimeter of each pattern). The method includes consecutively changing, for at least a portion of the forming of said three-dimensional object, the pattern between consecutive slices in a sequence of sequentially presented patterns of exposure that facilitates the flow of the polymerizable liquid to the build surface.
