Abstract:
According to some embodiments, system and methods are provided comprising receiving, via a communication interface of a distortion and correction module comprising a processor, a defined geometry for one or more parts, wherein the parts are manufactured with an additive manufacturing machine; discretizing the defined geometry into a mesh including a plurality of nodes; predicting a distortion of a position of each node of the plurality of nodes; determining whether the predicted distortion position exceeds a pre-set tolerance; determining an adjusted pre-distortion position for each node of the plurality of nodes when the predicted distortion position exceeds the pre-set tolerance; predicting a distortion of the adjusted determined pre-distortion position for each node of the plurality of nodes; determining whether the distortion of the determined adjusted pre-distortion position exceeds the pre-set tolerance; and printing the part when one of the predicted distortion position and the predicted adjusted pre-distortion position is below the pre-set tolerance. Numerous other aspects are provided.
