Abstract: Some embodiments facilitate creation of an industrial asset item via an additive manufacturing process wherein motion is provided between a build plate and a print arm. A correction engine may receive, from an industrial asset item definition data store containing at least one electronic record defining the industrial asset item, the data defining the industrial asset item. A correction engine computer processor may then correct the motion provided between the build plate and the print arm such that the motion deviates from a path indicated by the data defining the industrial asset item. The three-dimension printer may be a rotary printer such that the build plate rotates about a vertical axis and moves along the vertical axis during printing. In these cases, a pre-compensation algorithm may be applied to correct the motion provided between the build plate and the print arm before transmitting data to the three-dimensional additive manufacturing printer.

Abstract: A component is fabricated in a powder bed by moving a laser array across the powder bed. The laser array includes a plurality of laser devices. The power output of each laser device of the plurality of laser devices is independently controlled. The laser array emits a plurality of energy beams from a plurality of selected laser devices of the plurality of laser devices to generate a melt pool in the powder bed. A non-uniform energy intensity profile is generated by the plurality of selected laser devices. The non-uniform energy intensity profile facilitates generating a melt pool that has a predetermined characteristic.

Abstract: Methods, apparatus, systems and articles of manufacture are disclosed to generate a workscope. An example apparatus includes a workscope mapper, workscope strategy analyzer, and workscope selector. The workscope strategy analyzer is to evaluate each of the plurality of workscopes using dynamic optimization to determine a maintenance value and benefit to an asset associated with each workscope based on a stage in a remaining life of a constraint at which the evaluation is executed and a state of the asset. The dynamic optimization is to determine a prediction of the maintenance value based on a probability of a future change in state and associated workscope value until the end of life of the constraint. The maintenance value, used to select a workscope from the plurality of workscopes, is to be determined by the dynamic optimization as a sum of the associated workscope values until the end of life of the constraint.
