Additive manufacturing processes have evoked great interest for aerospace applications as they attain highly complex parts at low production volumes and have demonstrated reduction in component lead times. Over the past 30 years we have seen significant growth, evolution, and implementation of these processes from the laboratory to the factory floor. With the formation of geometrically complex features via additive manufacturing entering a stage deep understanding, recent research has evolved to explore the fabrication of spatially-tailored materials. This talk will discuss ongoing projects at the Materials and Manufacturing for Aerospace and Extremes Laboratory (MMAX Lab) related to the use of additive manufacturing for spatially-tailored functionality. I will highlight two projects, demonstrating methods for generating spatially-tailored porosity and microstructure. For porosity, I’ll discuss work on the fabrication components with parameter-induced porosity in powder bed fusion. For microstructure, I’ll present work on the control of microstructure and deformation of ceramics via reactive binder jet additive manufacturing. This presentation aims to provide a perspective on the possibilities for spatial tailoring of materials and the current state-of-the-art in processing science for compositional control.
