Abstract: A method for repairing a structure in an additive manufacturing system is provided. The method includes detecting a defect in a structure formed using an additive manufacturing process, the structure including a first surface that faces a powder containing region and a second surface that faces a substantially powder free region, generating a supplemental scan path that covers at least a portion of the structure based on a location of the detected defect, and controlling a consolidation device, based on the supplemental scan path, to remedy the defect.

Abstract: An additive manufacturing system includes an excitation energy source for generating a melt pool in a build material based on a build parameter. The system includes a sensing energy source and a first scanning device that directs the sensing energy source across the build material. The build material emits an ambient quantity of electromagnetic radiation prior to being contacted by an energy beam from the sensing energy source, and a sensing quantity of electromagnetic radiation different than the ambient quantity after contact by the energy beam. The system includes an optical system having an optical detector for detecting the sensing quantity of electromagnetic radiation and generating a detection signal in response. A computing device receives the detection signal and generates a control signal in response. The control signal is configured to modify the build parameter based on the sensing quantity of electromagnetic radiation to achieve a desired melt pool characteristic.

Abstract: A system for fabricating a component includes an additive manufacturing device and a computing device. The additive manufacturing device is configured to fabricate a first component by sequentially forming a plurality of superposed layers based upon a nominal digital representation of a second component, which includes a plurality of nominal digital two-dimensional cross-sections, each corresponding to a layer of the first component. The computing device includes a processor, wherein for an ith layer of the first component, the processor is configured to (a) generate a cumulative compensation transformation; (b) apply the cumulative compensation transformation to the nominal digital two-dimensional cross-section corresponding to the ith layer to create an intermediate digital two-dimensional cross-section corresponding to the ith layer; (c) determine a local compensation transformation; and (d) apply the local compensation transformation to the intermediate digital two-dimensional cross-section corresponding to the ith layer.

Abstract: A dataset including boundary representations of shapes associated with an item being designed for manufacture is accessed by a semantic processing module. A semantic graph of each of the boundary representations of shapes is generated and a numerical processing module computes geometric attributes of each of the shapes. The semantic graph of a shape is updated based on any geometric attributes computed for the shape. The semantic graphs are then compared to a repository of semantic graphs of manufacturing features to identify instances of manufacturing features. Geometric attributes associated with each instance of a manufacturing feature are then computed. For each instance, the associated geometric attributes are compared against a repository of semantic manufacturing rules to determine whether the instance is in compliance with the rules. A user designing the item is alerted to the presence of any instances of manufacturing features that are not in compliance with the rules.
