| Abstract Scope |
Synchrotron techniques have emerged as powerful tools for studying additive manufacturing (AM) processes. Many highly transient phenomena and non-equilibrium structure dynamics involved in AM have been investigated using operando x-ray imaging and diffraction. These experiments have advanced the field by: (i) quantitatively measuring key process and material parameters for model calibration and validation; (ii) enabling mechanistic studies of defect formation and microstructure evolution; and (iii) providing high-fidelity ground truth for benchmarking process sensing techniques. Over the past decade, this research community has grown rapidly, with operando experiments now conducted at nearly all major synchrotron facilities worldwide and applied across a broad range of AM processes. In this presentation, I will highlight insights gained from our previous synchrotron studies and discuss the remaining questions that could potentially be addressed in the next research phase. I will also present the new opportunities and challenges associated with experiments at 4th-gen synchrotron facilities. |
