  • Additive layering method using improved build description
    Patent number: 9757902
    Abstract: A build description is created for a part intended to be built by additive layering. The build description includes a description of the part broken down into constituent substructures and a build sequence for the substructures. A power schedule calculation method utilizes the build description and an idealized geometry to predict laser power levels on an additive path during laser deposition. The method calculates beam power for any point along the path traveled to form the build. Each point along the path has associated with it an idealized geometry comprising a melt pool, hot zone and bulk portion.
