Abstract: A computer program product comprising a non-transitory computer-readable medium storing instructions, that when executed by a computer processor, cause the computer processor to perform obtain a model defining a geometry of a component for manufacturing using an additive manufacturing system, discretize the geometry of the component into a plurality of voxels, each voxel representing a volumetric portion of the component, identify voxels of the plurality of voxels having a value of stress greater than a threshold value, determine regions of the component contributing to the identified voxels having the value of stress greater than the threshold value through a build process simulation configured to iteratively simulate modifications to voxels of the component so that the value of stress of the identified voxels is reduced, modify the geometry of the regions of the component, and store an updated model of the component incorporating the modifications to the geometry.

Abstract: An example additive manufacturing apparatus includes an energy source to melt material to form a component in an additive manufacturing process, a camera aligned with the energy source to obtain image data of the melted material during the additive manufacturing process, and a controller to control the energy source during the additive manufacturing process in response to processing of the image data. The controller adjusts control of the energy source based on a correction determined by: applying an artificial intelligence model to image data captured by a camera during an additive manufacturing process, the image data including an image of a melt pool of the additive manufacturing process; predicting an error in the additive manufacturing process using an output of the artificial intelligence model; and compensating for the error by generating a correction to adjust a configuration of the energy source during the additive manufacturing process.
