Abstract
Methods and systems comprise new design procedures that can be implemented for additive manufacturing technologies that involve evaluation of stress concentration sites using finite element analysis and implementation of scanning strategies during fabrication that improve performance by spatially adjusting thermal energy at potential failure sites or high stress regions of a part.
