In this study, novel nozzles for cement paste 3D printing are designed and optimized for higher interlayer strength via experiment and volume-of-fluid (VOF) based simulation, in terms of various outlet shapes and two nozzle components namely the interface shaper and the side trowel. These nozzles ar...
