Extrusion-based 3D printing using ‘cement inks’ is a promising emerging technology in the construction and infrastructure industries. However, the pressure used to drive extrusion may have dynamic effects on the composition and microstructure of formed filaments. The effects of the extrusion process on microstructural mechanical properties are not well understood. This study employs grid nanoindentation coupled with scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS) to examine the changes in mechanical and chemical properties of a cement ink’s heterogeneous microstructure between regions of 3D printed samples corresponding to different stages of the printing process.
