Abstract
A device for fabricating a solid freeform object includes a stage that rotates, a discharging device disposed over the stage and includes a discharging head each having one or more nozzles, the discharging head for discharging a curing composition to the stage and an exposing device disposed over the stage that exposes the stage to active energy, wherein the distance between the stage and the discharging device is variable and the distance between the stage and the exposing device is variable, wherein the shorter direction of the discharging head is perpendicular to the direction from the center of rotation of the stage toward the peripheral of the stage, wherein the number of the nozzles along the shorter direction increases in the direction from the center of rotation of the stage toward the peripheral of the stage.
