Additive manufacturing (AM) has attracted significant attention due to its geometrical flexibility for modern industrial parts design and manufacture. There is a growing demand for lightweight components to be built in this manner. However, the number of qualified aluminium alloys for this innovative process is still very limited compared to the wide range of alloys available for conventional manufacturing. In the present study, a number of alloys based on the Al-Sc system were designed and evaluated for SLM based on a laser remelting method. The microstructures of the developed alloys were systematically studied by various characterisation techniques, including scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Microhardness testing was used to evaluate the age hardening performance. Underlying mechanisms governing the relationships between alloy composition, processing method, microstructure and properties were elucidated. Finally, the suitability of this alloy design approach for SLM is discussed and future work directions are proposed.
