Abstract: A powder processing machine includes a work bed, a powder deposition device operable to deposit powder in the work bed, at least one energy beam device operable to emit an energy beam with a variable beam power and direct the energy beam onto the work bed with a variable beam scan rate to melt and fuse regions of the powder, and a controller operable to dynamically control at least one of the beam power or the beam scan rate to change how the powder melts and fuses. The controller is configured to determine whether an instant set of process parameters falls within a defect condition or a non-defect condition and adjust at least one of the beam power or the beam scan rate responsive to the defect condition such that the instant set of process parameters falls within the non-defect condition.

Abstract: A structure includes a first body section that has a wall that spans in a vertical direction. The wall has a relatively thin thickness with respect to a length and a width of the wall. A second body section is arranged next to, but spaced apart from, the first body section. A gusset connects the first body section and the second body section. The gusset extends obliquely from the wall of the first body section with respect to the vertical direction such that the gusset is self-supporting. The first body section has a geometry that corresponds to an end-use component exclusive of the gusset.

Abstract: An exemplary method for determining a set of additive manufacturing parameters includes, a) determining a nominal parameter of at least one surface of a component, b) determining at least a second order variation in the nominal parameter, c) predicting an actual resultant dimension based at least in part on the nominal parameter and the second order variation, and d) adjusting at least one additive manufacturing process parameter in response to the predicted actual resultant dimension.

Abstract: A system for additive manufacturing a component includes an additive manufacturing machine for building a component layer by layer and a first sensor configured to collect a first physical property data for each layer of the component as each layer is formed by the additive manufacturing machine. The system also includes a second sensor configured to collect a second physical property data for each layer of the component as each layer is formed by the additive manufacturing machine. A computing device is operatively connected to the first and second sensors and configured to receive the first physical property data and the second physical property data of the component and configured to compare the first physical property data with the second physical property data to determine a potential failure mode in the component.
