About

N. Schell is a leading figure in advanced manufacturing, with a primary focus on wire and arc additive manufacturing (WAAM) and thermomechanical processing. Their most significant contribution is the pioneering development of hot forging wire and arc additive manufacturing (HF-WAAM), a novel variant that integrates in-situ forging during deposition. This breakthrough, detailed in their highly cited 2020 paper (166 citations), leverages high-temperature viscoplastic deformation and subsequent recrystallization to refine microstructure and enhance mechanical properties, directly addressing key limitations of conventional WAAM such as porosity and coarse grain structures. Schell’s work has fundamentally reshaped how researchers approach metal additive manufacturing by merging deformation and deposition, achieving near-wrought properties in as-built components. Their research has garnered substantial attention, with the HF-WAAM paper becoming a cornerstone reference in the field. Beyond this, Schell has contributed to understanding process-structure-property relationships in additive and forging processes, making their work essential for engineers seeking to produce high-integrity, large-scale metal parts. Their innovative approach continues to inspire new pathways in hybrid manufacturing.
