Abstract Scope Conventional construction relies heavily on cement, raising concerns about resource depletion and environmental impact. However, geopolymers offer a promising alternative. By substituting conventional cement with copper mine tailings to produce geopolymer material, we can optimize cement usage and address environmental concerns such as acid mine drainage. Geopolymerization, the process of creating geopolymers, stabilizes the heavy metals often found in mine tailings. Moreover, 3D printing emerges as a promising technique for manufacturing geopolymer materials. This study investigates the influence of printing parameters such as nozzle diameter/layer height ratio and printing speed on the stability and quality of printed geopolymer material. Different 3D-printed designs incorporating features like vertical edges and overhangs were evaluated for factors such as delamination, surface finish, and dimensional accuracy under various printing settings.
