Lightweight design is a common way of reducing mass while enhancing the performance mechanical components. The paper proposes method to analyse substitution bulk volume with optimised lattice structures. approach considers an early DoE analysis explore space, Finite Element Analysis evaluate feasibility possible solutions, and Artificial Intelligence tools look for optimal including Genetic Algorithms Response Surface Methods. To validate methodological approach, this work optimisation lightweight diesel engine connecting rod, redesigned using Triply Periodic Minimal (TPMS) structures where they are functionally convenient. TPMS cells analysed gyroid, diamond, SplitP. Laser-Powder Bed Fusion (L-PBF) Additive Manufacturing process considered during redesign phase. resulting rod achieves roughly 614 g, obtaining more than 50% initial weight, gyroid titanium alloy powders such as Ti6Al4V.
