A growing community of users is beginning to rely upon physics-based process simulation tools to provide insight into metal additive manufacturing processes. Predictions of residual stress, distortion, supports, thermal history, microstructures, porosity, and more is now possible. By understanding the complex correlations between build orientation, support strategy, machine settings, powder type and part geometry, users can more quickly optimize their process to enable part qualification and to achieve build success. During this presentation, a series of case studies will be used to illustrate the power of predictive simulation tools. Specific examples will include the use of 3DSIM’s exaSIM software tool to predict optimized support structure distributions, residual stress and part distortion for different build orientations and part assumptions; and the use of 3DSIM’s FLEX software tool to predict the thermal history of parts based upon scan strategy and laser settings, and how that thermal history is linked to build defects and part microstructure.
