Abstract
Among the Additive Manufacturing (AM) technologies, 3D extrusion of viscous pastes has been highlighted because of its great flexibility of materials that can be processed, high material utilization and for enabling to produce parts with complex-shaped geometries and isotropic properties. However, there is a lack in the investigation on manufacturing metals by 3D extrusion of viscous pastes published in the literature. In this context, the focus of this study was on evaluating the printability of copper pastes. The pastes were fabricated using two water-based binder system. By systematically varying the powder load and binder composition, we aimed to identify the binder composition that yielded the desired viscosity and printability characteristics. This information is crucial for ensuring successful additive manufacturing processes. Overall, this investigation provided valuable insights into the development of copper pastes for 3D extrusion, highlighting the importance of binder selection in achieving the desired material properties and process performance.
