Additive manufacturing (AM) processes have proven to be a perfect match for topology optimization (TO), as they are able realize sophisticated geometries in unique layer-by-layer manner. From viewpoint, however, there is significant likelihood of process-related defects within complex geometrical features designed by TO. This because TO seldomly accounts process constraints and conditions typically perceived purely design tool. On the other hand, advanced AM simulations shown their potential reliable tools capable predicting various hence serving second-to-none material tool achieving targeted properties. Thus far, these two geometry been traditionally viewed entirely separate paradigms, whereas one must conceive them holistic computational instead. More specifically, models provide input physics-based TO, where consequently, not only component will function optimally, but also near-to-minimum defects. In this regard, we aim at giving thorough overview concepts applied AM.
