Abstract Scope |
Over the past decade, operando synchrotron X-ray diffraction and imaging techniques have emerged as powerful tools for studying rapid transient phenomena within and around the melt pool during laser-based additive manufacturing processes. These measurements necessitate specialized sample environments that are compatible with synchrotron (and neutron) beam lines while closely mimicking the conditions found in industrial additive manufacturing devices.
This presentation showcases the approach undertaken at the Paul Scherrer Institute to address this challenge. We have successfully developed a series of miniaturized devices that enable operando laser-powder bed fusion experiments, seamlessly integrating with synchrotron X-ray diffraction/imaging, X-ray tomography, and neutron diffraction/Bragg edge imaging. Our systems offer real-time insights into the complex dynamics of additive manufacturing processes at the microstructural level.
In this work, I will present the design, development, and characterization of our miniaturized devices, highlighting their capabilities and demonstrating their utility in capturing key transient phenomena. |
