About

Nahum Travitzky is a leading figure in the field of ceramic additive manufacturing, with a particular focus on the advanced fabrication technique known as robocasting. His research centers on developing novel material systems and processing strategies to create complex, high-performance ceramic and composite structures. Travitzky’s major contributions include pioneering the robocasting of intricate lattice structures, as demonstrated in his highly cited 2013 work on alumina hollow filaments (97 citations). He has also advanced the field by developing co-extrusion methods to create core-shell composites, such as carbon-alumina filaments, enabling the combination of disparate material properties within a single printed part. His work extends to the fundamental understanding of the robocasting process itself, using computational modeling (smoothed particle hydrodynamics) to predict filament behavior and investigating the critical role of particle reorientation during drying. With a citation count exceeding 140 for his most prominent works, Travitzky’s research is foundational for engineers and scientists seeking to push the boundaries of what is possible in 3D printing of ceramics, from structural components to functional devices.
