- Resumen
Additive Manufacturing (AM) technologies enable the fabrication of geometrically complex parts which promote the creative design and are starting to reshape the way products are conceived and designed. Given the capabilities of these technologies, specially the freedom in design, it is now possible to incorporate the most challenging demands of the industry into the product development. Nevertheless, in order to fully explore and take benefit of the remarkable possibilities of these technologies, innovative design approaches should be developed, so as to shift from traditional design processes, oriented to mass production and tooling, towards methods taking account of the potentials, the limitations and special features of additive technologies. This PhD Thesis explores and develops design strategies for providing a potential added value in the direct part production of applications for the energy, health and transport sectors, using vat photopolymerization systems. These systems lead to highly precise manufacturing in a wide set of photopolymers and high-performance ceramics, by resorting to additive photopolymerization of ceramic slurries. The strategies converge into an integrative Design for Additive Manufacturing (DfAM) methodology, specially developed and deployed for vat photopolymerization technologies, which in turn support: lightweight design and downsizing, through the use of metamaterials or topological optimization; integration of functionalities; incorporation of controlled surface properties; minimization of eco-impacts and enhancement of the mechanical, thermal and fluidic performance. Therefore, this research, performed with the support of the EU Horizon 2020 "ToMax: Toolless manufacture of complex structures" project, presents novel shape grammars, end-user parts and demonstrators in polymers and ceramics, which are supported by design guidelines resulting from experimental analysis and process modeling of the operated systems. Finally, systematic procedures for the assessment of the environmental issues are developed for promoting the industrial impact these technologies and related applications.
