Abstract
This study evaluates the feasibility of incorporating waste printed circuit board glass fiber powder (WPCBP) into 3D-printed cement mortar for structural applications. Printability was assessed by measuring initial setting time, extrudability, flowability, and buildability. Mechanical properties were evaluated through compressive, flexural, and splitting tensile tests. Among all specimens, the mortar with a WPCBP-to-cement ratio of 0.2 exhibited the best mechanical performance across all tests. Four-point bending tests on 3D-printed truss elements, validated by finite element simulations, confirmed that WPCBP enhances the mechanical and structural behavior of the components. In addition, the results highlighted pronounced anisotropic behavior in the 3D-printed specimens, with strength dependent on the printing and loading directions. Overall, integrating WPCBP with 3D printing improves material performance and facilitates effective recycling of non-metallic electronic waste.
