The present Thesis "Qualification of SLM - Additive Manufacturing for Aluminium Alloys" considers the suitability of two aluminum alloys for the additive manufacturing technique Selective Laserbeam Melting (SLM). High cooling rates can be realised in SLM which allow the use of the tailored Al-alloy options Scalmalloy and SilmagAl. The investigations deepen the scholarly understanding of processing both alloys in SLM. Different aspects of the process chain are described, analysed and discussed with regard to define powder and material specifications for aerospace applications. Main process influencing powder characteristics are identified and characterising techniques are discussed. The additive manufactured material of both alloys is comprehensively investigated regarding mechanical and physical properties. As result, different processing routes are identified which aim to meet the final proposed material specification for principle structural elements (PSE) and non-principle structural elements (non-PSE) in aerospace qualifications.
