Design, production and qualification of structural components fabricated by metal additive manufacturing: a case study

Abstract

The study focuses on designing fatigue-critical components produced by Additive Manufacturing (AM), developing a comprehensive workflow for producing L-PBF metal parts, and evaluating their structural integrity through fatigue testing. The approach includes topological optimization, simulation of the AM process, fabrication using an industrial-grade Laser powder bed fusion system and AlSi10Mg alloy powder, and evaluation of material and mechanical properties.

Lo studio è stato orientato alla progettazione di componenti strutturali realizzati tramite additive manufacturing (AM), identificando le fasi principali per lo sviluppo delle parti prodotte in AlSi10Mg tramite fusione laser selettiva, considerando l’ottimizzazione topologica della geometria, la simulazione del processo AM, la produzione delle parti e la qualifica dell’ integrità strutturale attraverso prove di fatica.
