Additive manufacturing of spare part supported by digital design concept

Material processing (P) method defines through the forming microstructure (S), what kind of properties (P) the material has in certain environment and how the material performs (P). Integrated computational material engineering (ICME) transfers the traditional material development based on experimental trial and error approach into digital approach and enables new angles for component design through true performance based material development. Digital design and digital manufacturing combined with digital material design masters the life cycle of a component with endless variation possibilities in extremely short time periods. The digitally developed, performance optimised, load bearing components can be executed through powder metallurgical (PM) route manufactured by 3D printing, e.g., selective laser melting (SLM). The concept based on digital design from component level down to materials microstructure based on the performance needs is presented. Digital design route is compared to the experimental route. The benefits are presented through OEM case example.
