1. A method of operating an additive manufacturing apparatus, the method comprising:
providing parameters of a build process to a control system;
performing a first indexing of a resin support having a resin applied thereto to translate the resin support a first linear distance into a first print module and a second print module;
moving a first stage within the first print module to a first stage position based on the provided parameters to form a first layer of a first component;
moving a second stage within the second print module to a second stage position based on the provided parameters to form a first layer of a second component;
radiating a first image from a first radiant energy device at a first portion of resin positioned between the first radiant energy device and the first stage; and
radiating a second image from a second radiant energy device at a second portion of resin positioned between the second radiant energy device and second stage.
