| Abstract Scope |
Molten Metal Jetting (MMJ) belongs to the group of metal-based additive manufacturing processes, where components are built up layer by layer through repetitive material deposition. In contrast to most fusion-based methods, LMP does not require a beam source for material melting or powders, as the material is supplied as wire, melted in a crucible, and deposited drop by drop. Utilizing a piezoelectrically driven actuator, near-net-shape manufacturing with droplet diameters ranging between 500 µm and 750 µm are achievable. Overall, the advantages of LMP enable efficient, cost-effective, and high-quality component manufacturing. This paper focuses on establishing and qualifying, industry-relevant aluminum alloys to leverage MMJ´s potential for industrial production and applications in lightweight construction. Using the example of AlSi12, potentials and challenges regarding manufacturing parameters and mechanical properties are delineated. Based on this, requirements are derived to process higher magnesium-containing alloys such as AlSi10Mg and EN AW-7075 in the future. |
