Fiber-reinforced polymer composite (FRPC) 3D printing is revolutionizing the manufacturing of complex composite structures. Grid-stiffened composites are one of the applications that prized for their high specific stiffness and buckling resistance. However, the discrepancies between design and manufacturing and their influence on the properties of as-fabricated structures are often insufficiently considered. Herein, the manufacturing discrepancies are taken into account during the design stage by developing a novel path-planning approach specifically tailored for FRPC 3D printing of grid-stiffened composite structures with curved stiffeners. Firstly, an Euler graph-based technique is applied to obtain continuous paths that are well aligned with curved stiffeners and possess minimum fiber cutting frequency and printing time. These continuous paths are further optimized for buckling resistance using inexpensive yet accurate updated finite element models. These computational models are coupled with experimental characterization results to provide evaluations that consider manufacturing imperfections and as-fabricated properties. Within this performance-aware process, buckling resistance is optimized based on a fixed input geometry, with joint configurations as variables. Finally, the proposed path-planning approach is experimentally validated and proven to be effective in integrating performance considerations into both the design and manufacturing stages, leading to a more efficient and performance-optimized fabrication process for grid-stiffened composite structures.
