1. An additive manufacturing apparatus comprising:
a common resin support configured to support a first resin and a second resin, the first resin laterally offset from the second resin by a gap defined between the first resin and the second resin in a Y-axis direction;
a support plate including a window;
a stage configured to hold one or more cured layers of the first resin or the second resin to form a component positioned opposite the support plate;
a radiant energy device positioned on an opposite side of the common resin support from the stage and operable to generate and project radiant energy in a patterned image through the window;
an actuator assembly configured to move the stage in a Z-axis direction and in the Y-axis direction;
a frame operably coupled with the stage, the radiant energy device, and the support plate, the frame further coupled with a mounting plate; and
a first slide assembly, wherein the frame, the stage, the radiant energy device, and the support plate are moveable relative to the mounting plate along the first slide assembly.
