Relating print velocity and extrusion characteristics of 3D-printable cementitious binders: Implications towards testing methods

This study aims to relate print velocity to critical parameters extracted from a controlled ram extrusion test, towards a test method to expedite the selection of materials and process parameters for 3D-printing of cementitious materials. Higher print velocities, while aiding faster construction, results in a need for higher extrusion pressure, while lower velocities interfere with extrudate quality through effects such as water filtration....
