Title: Towards spatial tailoring of ceramics via additive manufacturing

Abstract: Over the past 30 years we have seen significant growth, evolution, and implementation of additive manufacturing processes from the laboratory to the factory floor. For polymers and metals, additive manufacturing has achieved highly complex parts at low production volumes and reduction in component lead times. For ceramics, the formation of high-density, geometrically complex features via additive manufacturing is still a challenge. Yet, the fabrication of multi-material spatially-tailored components is of great interest for nuclear energy, quantum devices, power electronics. This talk will discuss ongoing projects at the Materials and Manufacturing for Aerospace and Extremes Laboratory (MMAX Lab) at UCSB related to the use of additive manufacturing for deposition of ceramic materials with spatially-tailored functionality. I will highlight two projects, demonstrating methods for generating spatially-tailored microstructure and composition. First, I’ll present work on the control of microstructure and deformation of ceramics via reactive binder jet additive manufacturing. Second, I’ll showcase preliminary work on the exploration of nanoparticle material jetting fundamentals for multi-material ceramic components. This presentation aims to provide a perspective on the possibilities for spatial tailoring and the current state-of-the-art in processing science for compositional control of ceramics.

Bio: Daniel Oropeza is an Assistant Professor in the Materials Department at UCSB. His group at UCSB couples the study of material synthesis and characterization, machine and equipment design, and manufacturing process fundamentals, to develop next-generation alloys and ceramic materials. Group expertise includes testbed fabrication, powder rheology and characterization, and sinter-based ceramics processing. Daniel completed a B.S. at the University of Texas at Austin in 2012, an M.S. in aeronautics and astronautics from Stanford University in 2014, a Ph.D. in mechanical engineering at the Massachusetts Institute of Technology in 2021, and was a postdoctoral fellow at NASA’s Jet Propulsion Laboratory.
