Abstract
Recently, additive manufacturing (AM) of metals has enjoyed significant advancement. While the mainstream AM methods utilize high-energy power beams to melt metal powders, other low-cost alternatives are also being developed (e.g., direct ink printing). In this study, a copper powder-binder paste is developed, which is not only capable to be used for direct printing, but also to be cast using soft molds. Dense three-dimensional parts can be obtained by sintering green bodies. The electrical and mechanical properties of the sintered samples are evaluated by conductivity, hardness measurements and tensile tests, respectively. The results are comparable to other powder processed copper materials.
