Abstract
Techniques and systems for enhancing vertical edges during photopolymer-based three-dimensional (3D) printing are described. A described technique includes accessing an original image corresponding to a slice of a 3D model prepared for printing on a 3D printer; accessing a pixel reduction factor that is associated with an increased exposure duration parameter; classifying pixels of the original image; reducing intensity levels of the interior pixels by the pixel reduction factor so that corresponding printing areas receive first curing doses under the increased exposure duration parameter and the reduced intensity levels that are comparable to doses received under an unmodified exposure duration parameter and unreduced intensity levels; maintaining intensity levels of the exterior pixels so that corresponding printing areas receive second curing doses under the increased exposure duration parameter that are greater than doses associated with the unmodified exposure duration parameter; and outputting a resulting modified image for 3D printing.
