| description | 3D cementitious material printing process, which is typically used in building and
construction area, is getting attractive for both industry and academic. Rotational rectangular
nozzle is widely applied in 3D cementitious material printing process to improve surface finishing
while maintaining printing speed. However, due to the fact that curved printing path has longer
outer side than inner side, material printed by rotational rectangular nozzle in curved printing
trajectories becomes unevenly distributed, causing deposited filament to be offset from expected
position. In order to ensure uniform material distribution for curved printing trajectories, rotational
trapezoid nozzle shape is proposed for 3D cementitious material printing process. In this paper, the
material distributions for various trapezoid nozzle were studied by numerical simulations.
Validation experiments showed that these simulation results can be used to predict material
distribution for curved printing trajectories with trapezoid shaped nozzle. A variable geometry
nozzle utilizing the simulation results as controller was then proposed for 3D cementitious material
printing process. |
