About
Valdemar R. Duarte is a leading innovator in advanced manufacturing, whose work is reshaping the landscape of metal additive processes. His primary research focuses on the development and refinement of Wire and Arc Additive Manufacturing (WAAM), with a particular emphasis on a groundbreaking variant he pioneered: Hot Forging Wire and Arc Additive Manufacturing (HF-WAAM). Duarte’s major contribution lies in integrating in-situ hot forging directly into the WAAM process. By locally forging the deposited material at high temperatures, his technique induces viscoplastic deformation and promotes recrystallization, dramatically improving the mechanical properties and microstructural quality of printed components. His seminal 2020 paper on this method has garnered 166 citations, underscoring its profound impact on the field. More recently, Duarte has advanced the practical implementation of HF-WAAM by developing a novel robotic cell, meticulously investigating process parameters and vibration dynamics to enhance part accuracy and system stability. His work is not only pushing the boundaries of what is possible in additive manufacturing but also providing a viable path toward producing high-integrity, large-scale metal parts for demanding industrial applications.
