Abstract
The size control of 3D printed concrete filament limits application of 3D printed concrete technology. The accuracy of 3D printed concrete will benefit from stability of extrusion flow. Therefore, it is necessary to study the effective factors on extrusion flow. In this paper, the effects from fluidity and mass of loading in material tank on extrusion flow were discussed. The special phenomenon effective on extrusion flow during the printing process was discovered and named as ‘collapse’ and ‘critical loading’. Meanwhile, the liner relationship between fluidity and extrusion flow per unit mass of initial loading in material tank was observed. A feasible method for extrusion flow prediction was proposed based on mathematical results in this study. And some advices were provided according to the experience from this research.
