摘要： A method of additively manufacturing three-dimensional objects, and/or a method of controlling one or more irradiation parameters of the energy beam system, may include determining an irradiation setting using an irradiation control model and outputting an irradiation control command to an energy beam system based at least in part on the irradiation setting. The irradiation control model may be configured to determine the irradiation setting based at least in part on a power density factor and/or an irradiation vector factor. The irradiation control command may be configured to change one or more irradiation parameters for additively manufacturing a three-dimensional object. An additive manufacturing system may include an energy beam system and a control system that includes an irradiation controller. The irradiation controller may include a control module configured to perform such a method.

摘要： Methods for creating a cast component, along with the resulting cast components, are provided. The method may provide for a controlled grain structure in the resulting cast component. The methods may include heating at least a first portion mold under controlled conditions, such as when the first portion of the mold is buried in a ceramic powder.

摘要： Methods and apparatus for two-dimensional and three-dimensional scanning path visualization are disclosed. An example apparatus includes at least one memory, instructions in the apparatus, and processor circuitry to execute the instructions to identify at least one melt pool dimension using a beam parameter setting, the at least one melt pool dimension identified from a plurality of melt pool dimensions obtained by varying the beam parameter setting, identify a response surface model based on the plurality of melt pool dimensions to determine an effect of variation in the beam parameter setting on the at least one melt pool dimension, output a three-dimensional model of a scanning path for an additive manufacturing process using the response surface model, and adjust the beam parameter setting based on the three-dimensional model to identify a second beam parameter setting.

摘要： Methods and apparatus for two-dimensional and three-dimensional scanning path visualization are disclosed. An example apparatus includes a parameter determiner to determine at least one of a laser beam parameter setting or an electron beam parameter setting, a melt pool geometry determiner to identify melt pool dimensions using the parameter setting, the melt pool geometry determiner to vary the parameter setting to obtain multiple melt pool dimensions, and a visualization path generator to generate a three-dimensional view of a scanning path for an additive manufacturing process using the identified melt pool dimensions, the visualization path generator to adjust the laser beam parameters based on the generated three-dimensional view.
