This thesis focuses on the analysis and optimization of process parameters in additive manufacturing technologies, specifically DLP technology for the production of polymer components and LPBF technology for metallic components made of titanium alloy. To optimize the printing parameters, various tests were carried out, including density measurements, microscopic analysis of defect type, static tests. The physical and process characterization of the materials aims to identify their potential applications, primarily for the development of high-performance components that have to be as rigid, strong, and lightweight as possible. In this context, a case study is presented involving a skyhook, which is typically manufactured from bulk-machined maraging steel. As an alternative, a solution using Ti6Al4V alloy produced via LPBF is proposed. The operating stresses are analyzed, the component's fatigue life is estimated, and the results are validated through an experimental test.
Questa tesi tratta l’analisi e l’ottimizzazione dei parametri di processo di tecnologie additive, in particolare la tecnologia DLP per la realizzazione di componenti in materiale polimerico e la tecnologia LPBF per componenti metallici in lega di titanio. Al fine di ottimizzare i parametri di stampa sono stati effettuati diversi test, tra cui misure di densità, analisi del grado di difettosità e loro tipologia al microscopio, prove statiche. La caratterizzazione fisica e di processo dei materiali è volta ad individuare le possibili applicazioni di questi ultimi, principalmente per la creazione di componenti ad alte prestazioni, quindi più rigidi, resistenti e leggeri possibile. A tal proposito viene analizzato un caso studio riguardante uno skyhook, generalmente realizzato in acciaio maraging lavorato dal pieno. In alternativa, viene proposta una soluzione mediante l’impiego della lega Ti6Al4V stampata tramite LPBF, vengono analizzate le sollecitazioni in esercizio e viene stimata la vita a fatica del componente, infine vengono validati i risultati tramite una prova sperimentale.

Abstract
This thesis focuses on the analysis and optimization of process parameters in additive manufacturing technologies, specifically DLP technology for the production of polymer components and LPBF technology for metallic components made of titanium alloy. To optimize the printing parameters, various tests were carried out, including density measurements, microscopic analysis of defect type, static tests. The physical and process characterization of the materials aims to identify their potential applications, primarily for the development of high-performance components that have to be as rigid, strong, and lightweight as possible. In this context, a case study is presented involving a skyhook, which is typically manufactured from bulk-machined maraging steel. As an alternative, a solution using Ti6Al4V alloy produced via LPBF is proposed. The operating stresses are analyzed, the component's fatigue life is estimated, and the results are validated through an experimental test.| File | Dimensione | Formato | |
