Pioneer of laser directed energy deposition (DMD/LENS) and laser cladding
Jyotirmoy Mazumder is Robert H. Lurie Professor of Engineering at the University of Michigan and one of the founding pioneers of laser-based directed energy deposition, beginning work on laser cladding and powder-fed laser processing in the late 1970s and 1980s. He is the inventor of Direct Metal Deposition (DMD), a form of DED that became one of the first commercially deployed laser AM processes, and holds multiple foundational patents in laser-based metal deposition. His research has produced seminal models of melt-pool fluid dynamics, solidification morphology, and microstructure evolution in laser-deposited alloys, enabling closed-loop control strategies that maintain bead geometry and composition during multi-layer builds. Mazumder's group demonstrated real-time composition and microstructure control through in-situ spectroscopy integrated with the deposition head — a precursor to today's in-process monitoring systems. He is a member of the National Academy of Inventors and has received the ASME Blackall Machine Tool award for his contributions to manufacturing.
