Abstract: A method of forming the body portion of a three-dimensional object from a polymerizable liquid by the process of continuous liquid interface printing is described. The body portion has a plurality of contiguous segments, and the process includes advancing a carrier 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. In the present invention, the operating mode is changed at least once during the formation of the body portion for different contiguous segments of the body portion.

Abstract: A method of forming the body portion of a three-dimensional object from a polymerizable liquid by the process of continuous liquid interface printing is described. The process includes advancing a carrier 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, with the body portion having a plurality of contiguous segments and with the irradiating carried out in sequentially presented slices of exposure, each having a pattern that corresponds to a segment of the body portion. Each segment has a thickness (e.g., in Z or vertical dimension) during the forming thereof. In the present invention, slice thickness is changed among the slices at least once during the formation of the body portion.
