Abstract: A system and method for creating pre-compensated parts through additive manufacturing by providing more precise compensation in part regions either through a user specified selection of the region or an automatic selection of the region. An additive manufacturing system first generates a computer-aided design (CAD) image and then measures the physical representation of the component, then determines the amount to be compensated and generates a compensation field using multi-level b-spline morphing over the entire part to create a 3-D part. Embodiments can also include automation to determine the best level to morph all the points on the entire additive manufactured part, using incremental morphs, determining the correct morphing level locally, and using weights to determine what regions receive high level morphs as they are compensated.

Abstract: A system and method for analyzing build files in an additive manufacturing process in order to predict defects in an additive part. The system and method further include the steps of reading an additive build file containing a set of scan paths of a three-dimensional (3D) object for a build, the set of scan paths comprising a plurality of points, creating a transfer function from parameters in the build file that corresponds to a local melt pool shape at each point of the plurality of points along the scan paths, and identifying potential defective portions of the additive part including at least one of pores, excessive melting, or surface finish based on the transfer function.

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 apparatus may include a processor, memory modules, and machine-readable instructions stored in the memory modules. When executed by the processor, the instructions may cause the apparatus to receive image data of one or more laser strikes on a build plane, the image data indicating positions of a first set of fiducial strikes made by a first laser on the build plane and positions of a second set of fiducial strikes made by a second laser on the build plane, determine relative positions of the first set of fiducial strikes and the second set of fiducial strikes with respect to each other from the received image data, compare the determined relative positions of the first and second sets of fiducial strikes with respect to each other to expected relative positions of the first and second sets of fiducial strikes with respect to each other, and determine whether the first laser and the second laser are misaligned with respect to each other based on the comparison.
