The complex microstructure evolution and heterogeneities in metal additive manufacturing (AM) continue to delay the adoption of AM parts by additional industries. Achieving uniform superior properties requires better fundamental understanding microstructural evolution. A suitable pathway gain such is via situ techniques as high-speed X-ray imaging, high-resolution infrared cameras, or synchrotron neutron diffraction. However, these methods are resource intensive. Modeling may be a more economical avenue, yet, make models robust reliable, data from often required. We believe that some cases, physical simulation originally developed for research on conventional processing forging, rolling, welding provide similar insights. This viewpoint article discusses existing experimental tracking during lab-scale settings, focusing Ni-based superalloys case study. proposed include Gleeble thermo-mechanical simulator, dilatometry, arc-melting heat treatment technique. These can also integrated into various X-ray, synchrotron, diffraction set-ups. discuss how insights derived thermo-kinetic modeling underpin observations simulations. Last, transmission electron microscopy evaluated powerful method with unparalleled resolution observing directly simulated processes. extended other alloy systems, enhancing scientific understanding, streamlining efficient development properties, promoting widespread AM.
