146082 - Fabrication of Ceramic/metal Composite Structures Using Additive Manufacturing 

Amidst the growing demand for innovative material design and fabrication technologies, this study explores the application of Additive Manufacturing (AM) techniques for processing composite materials with transverse thermoelectricity. By employing a modified dual-nozzle FDM 3D printer, we achieve precise mixing and positioning of two distinct materials to fabricate composite structures. The primary objective is to develop a novel 3D printing process for manufacturing transverse thermoelectric composite materials with superior performance. In this work, zinc oxide and copper are selected as the ceramic and metal phases. Powders of these materials are made suitable for 3D printing by adding binders and other organic solvents to adjust their flow behavior. The printing behavior, sintering behavior, the microstructures and the Seebeck performance will be discussed. This approach presents a new possibility for manufacturing transverse thermoelectric materials, offering advantages over traditional machining methods by addressing challenges related to high equipment costs and complex process control issues.
