Abstract
An additive manufacturing system, and associated methods, comprise an image projection system comprising a plurality of image projectors that project a composite image onto a build area within a resin pool. The composite image comprises a plurality of sub-images arranged in an array. The properties of a sub-image and the alignment of the position of the sub image within the composite image can be adjusted using a set of filters comprising an irradiance mask that normalizes irradiance, and a gamma adjustment mask that adjusts sub-image energy based on a reactivity of the resin.
