Abstract: A method for use in additively manufacturing an orthodontic aligner may include receiving a digital model of an aligner, processing the digital model of the aligner to modify the digital model based on predicted deviations during fabrication to generate a first updated digital model of the aligner, determining that whether the predicted deviations of a physical aligner additively manufactured based on the first updated digital model of the aligner are acceptable, and outputting the first updated digital model of the aligner for fabrication of the physical aligner by additive manufacture of the physical aligner.
