On the other hand, optimizing the filament deposition paths will provide an extra possibility to enhance the structural performance. To approach the reality, topology optimization for AM should deal with these directional variations. Specifically, the tensile modulus and strength in the raster direction, the transverse direction, and the build direction are all evidently different. The directional material properties are rooted in the layer-by-layer deposition process, which is a feature of the fused deposition modeling (FDM) technique. Among these topics, the design constraints imposed by the anisotropic properties of AM materials are of interest and will be addressed by the hybrid topology optimization technique proposed in this work. Despite the efforts, a lack of solutions is still the common issue in the topology optimization for AM as summarized by the literature. Detailed reviews on these topics can be found in. However, there are new design rules and unique constraints induced by AM, which introduce new challenges such as support structure design/elimination, minimum component size constraints, directional material properties, topology design interpretation, variable-density cellular structure design, and many others. Because the shape and topology are concurrently designed, topology optimization makes the greatest design freedom possible compared with shape-only or size-only optimization. Topology optimization has been treated as the main computational design method for AM. Several numerical examples were investigated to verify the effectiveness of the proposed method, while satisfactory optimization results have been derived. An asynchronous starting strategy is proposed to prevent the local minimum solutions caused by the concurrent optimization scheme. With this set-up, a concurrent optimization problem was formulated to simultaneously optimize the topological structure of the printing layer, the multipatch distribution, and the corresponding deposition directions. The level set method was employed to represent and track the layer shape evolution discrete material optimization (DMO) model was adopted to realize the material property interpolation among the patches. The ‘multipatch’ concept consists of each printing layer disintegrated into multiple patches with different zigzag-type filament deposition directions. The Layer 3D To Feature Class geoprocessing tool in ArcGIS Pro takes the 3D display properties of the input feature layer and outputs a 3D line or multipatch feature class.This paper presents a hybrid topology optimization method for multipatch fused deposition modeling (FDM) 3D printing to address the process-induced material anisotropy.
