Research of the Influence of 3D Printing Speed on Printing Dimension

In the process of 3D printing, the forming dimension of the extrusion fluid material will directly affects the printing precision. Under the given materials, the printing speed is one of the important parameters affecting the forming dimension of the material. Through numerical simulation, a dynamic three-dimensional model of the 3D printing process is established, and compared the spreading and forming dimension of the gelatin material under different printing speeds based on the volume of fluid (VOF) method, obtaining the influence of printing speed on the gelatin forming dimension. The results showed that both of the forming height and width of materials decrease with the increase of the printing speed, and the impact of the printing speed on the forming width of materials is more obvious.
