| Abstract Scope |
Powder components subjected to sintering should ideally homogeneously shrink and retain their original shapes. However, the real-world materials processing is influenced by many factors (e.g. temperature non-uniformity, external friction forces, and gravity) which during sintering cause inhomogeneous densification and shape distortions in final products. These issues also affect powder components obtained using additive manufacturing technologies, such as binder jetting and ceramic stereolithography, followed by sintering. Therefore, the fundamental understanding of the sintering process and the different sintering-influencing factors is of great importance for the development of modeling tools able to predict the resulting shapes and properties of the final sintered 3D-printed components. In the present work, a finite element model is developed in order to predict the sintering behavior of 3D-printed specimens under the influence of gravitational forces. Subsequently, the model results are validated through the comparison with the experimental test outcomes. |
