There is a need for advances in heat transfer manufacturability to achieve high heat transfer can be achieved with lower costs and smaller footprints. Our work focuses on improving the pool boiling heat transfer through enhanced solid-liquid interfacial characteristics by additively manufacturing multidimensional coatings and heater surface geometries. However, to fully harness the potential of additive manufacturing processes for industrial scale thermal manufacturing, it is critical to develop an understanding of why and how processing methods influence the composition and the structure. For various manifestations, the pool boiling performance of a surface is dictated by higher critical heat fluxes (CHF) and heat transfer coefficients (HTC) at lower wall superheat. In this talk, I will present our recent work on Fused Filament Fabricated (FFF) 3D printed copper with combined geometry and porosity that yielded higher heat transfer coefficients. Additionally, I will discuss our efforts of creating geometries through magnetically aligned metal inks that achieved 49.9% in CHF and 105% in HTC compared to plain copper surface. I will discuss the new fundamental mechanisms correlating wickability and altered three-phase contact angle that attributed to these enhancements.
