Metal additive manufacturing can three-dimensionally print engineering parts with complicated and customized geometries directly from a digital file. Due to the uniqueness of this layer-by-layer printing process, residual stress is the major challenge to print reproducible and reliable parts during cyclic heating and cooling. However, it is difficult for conventional methods to characterize residual strain of additively manufactured parts with complex geometries non-destructively. Here, we apply synchrotron energy-dispersive diffraction to investigate residual strain mapping of additively manufactured Inconel 718 blade. Two principle strain components can be obtained and the location-dependent residual strain mapping will be elucidated. The quantified residual strain mapping will be crucial for printing structurally-sound parts and benefit the validation and optimization of residual stress modeling in additive manufacturing.
