6. Conclusions and future works The aim of the reported research is the Generative Design of supporting structure for retrievals of small and medium scale for exhibition purposes. The usage of dedicated software and developed algorithms proved the significance of the method, reaching two different variants of supporting structures for each of the two case studies considered, a bronze axe and an aryballos. The obtained structures are additive manufacturable, lightweight and they also accomplish one of the main needs, translated into an aesthetic requirement, of minimizing the visibility of the supports from the observer viewpoint. In Fig. 10, the final assembly with supports and retrievals inside the exhibition case is reported, with the possible view of the observer.

In the next future, the number of case studies will be increased and further extended to large-scale retrievals. This research will be also extended with the usage of Lattice Structures and their topological optimization (LSTO) in a Generative Design approach. Studies will be also carried out concerning the usage of different materials (also soft materials, metals and multimaterials) and different kinds of basements, fixturing and manufacturing processes, with possible applications of Machine Learning in the process, mainly concerning the optimization of the supporting interfaces.
