Designs can be programmed as problems to be solved by using computational tools based on complex algorithms to optimize and produce more effective solutions. Additivemanufacturing technologies enhance these possibilities by providing great geometric freedom to the materialization phase. This work presents a design methodology for the optimization of parts produced by additive manufacturing and explores the synergies between additive manufacturing, parametric design, and optimization processes to guide their integration into the proposedmethodology. By usingGrasshopper, a visual programming application, a continuous data flowfor parts optimization is defined. Parametric design tools support the structural optimization of the general geometry, the infill, and the shell structure to obtain lightweight designs. Thus, the final shapes are obtained as a result of the optimization process which starts from basic geometries, not from an initial design. The infill does not correspond to pre-established patterns, and its elements are sized in a non-uniform manner throughout the piece to respond to different local loads. Mass customization and Fused Deposition Modeling (FDM) systems represent contexts of special potential for this methodology.eninfo:eu-repo/semantics/openAccess3305 Tecnología de la construcción3310 Tecnología industrialartículoadditive manufacturingFDMoptimizationparametric designinfill optimizationmass customizingODS 9 - Industria, innovación e infraestructura2073-4360
