Allied Vision EoSens Camera Captures the Physics of Metal 3D Printing at 20,000 Frames per Second

KU Leuven researchers used an Allied Vision EoSens high-speed camera to film metal Laser Powder Bed Fusion at 20,000 frames per second, capturing melt pool and spatter behavior in fine detail. The resulting data enhances defect prediction in LPBF and points toward better-controlled, potentially zero-defect metal 3D printing.

How close are we to integrating this kind of high-speed imaging and defect prediction into closed-loop, production LPBF systems at scale, and what barriers (cost, data processing, robustness) still stand in the way?
