Investigation of the Effect of the Lighting Step on the Strength of a Ceramic Product in 3D Printing
Year: 2020
Type: conference-paper
Abstract: The subject of this study is to assess the effect of such a 3D printing parameter by the SLA method as the lighting step (the distance between the lines of the beam motion when lighting the layer) on the mechanical properties of a ceramic object. For the study, the lighting step of 50 μm, 75 μm and 100 μm was used. The dependencies such as the Mises stresses, the displacements of the layers of the printed object relative to each other, and also the pressure arising in the layer were compared. To exclude edge effects, dependences were evaluated in the range from 500 μm to 1500 μm of the surface of the object layer, the layer thickness was 100 μm. These studies are necessary to optimize the 3D printing process, to minimize internal stresses and pressures in the printed object. The use of optimal printing parameters will improve the results of heat treatment and obtain objects with the required surface quality.
