Abstract Scope |
To design for printability in additive manufacturing, the material, and processing spacing need to be analyzed as well as visualized. However, designing for printability can be a costly process due to the involvement of experiments. Therefore, we propose a framework using the Cantor system that calculates the material properties using a CALPHAD model and a reduced-order model. Using the material properties, the melt pool geometry is calculated using one of the three thermal models - the analytical Eagar-Tsai model, the scaled Eagar-Tsai model, and the neural network Eagar-Tsai model – during the AM processing. Further, the printability map for an arbitrary alloy in the material system is constructed using defined criteria for lack of fusion, balling, and keyholing. In the end, the material system's susceptibility to balling and hot cracking is assessed to construct printability maps for compositions that are least susceptible to balling and hot cracking. |
