Abstract: A three-dimensional model (i.e., MCAD model) for additively manufacturing a physical object with a laser is received in a computer system. The laser is controlled or driven by a set of instructions. The instructions specify scan properties for scanning each of multiple deposit layers during the additive manufacturing. Two-dimensional (2D) maps representing the scan properties for the deposit layer are generated. Each 2D map includes values in grid points representing the deposit layer. Each 2D map corresponds to a respective scan property for the deposit layer. A trained machine learning model is invoked to predict a physical behavior of a layer of the physical object based on the 2D maps as an input. The input further includes a state map showing a state of an immediately prior deposit layer. The layer of the physical object corresponds to the deposit layer.
