This research highlights the significant environmental benefits of employing additive manufacturing for lightweighting in the automotive industry. By redesigning a component using topology optimization and substituting iron with aluminum, a 69% weight reduction was achieved. Although the additive manufacturing process itself exhibited higher specific energy consumption, the overall life-cycle assessment indicated a net reduction in carbon dioxide emissions and energy demand, primarily due to improved fuel efficiency during the product's use phase. This underscores the importance of considering the entire product life cycle when evaluating the sustainability of manufacturing choices.
