The chapter presents the concluding remarks of the book. The book aimed to introduce generative design to both specialized and non-specialized audiences, focusing on its application in aerospace. Generative design is closely linked with new creative design processes and a new manufacturing process. Specifically, the methodology is suited for additive manufacturing. In this sense, it can help obtain novel, lightweight designs that align with sustainable production objectives. Technological advances, such as big data, computing, and artificial intelligence, significantly enhance its capabilities. The suitability of this methodology in aerospace has been discussed by presenting several examples in previous chapters.
