| Abstract Scope |
Molten Metal Deposition (MMD) is a novel wire-based metal additive manufacturing (AM) technique with an initial focus on aluminium. MMD involves the direct liquefaction and deposition of wire feedstock onto a heated substrate. This method eliminates the need for auxiliary energy sources like lasers, binders, or support structures, thereby reducing thermal stress and enhancing process efficiency. MMD is particularly suited for the production of high-strength aluminium alloys in the 6xxx and 7xxx series. To optimize the parameters of this process, a detailed finite element analysis (FEA) is performed using an element-birth technique to accurately simulate the dynamic conditions during deposition. Following this, experimental validation of the thermal profiles of the components is carried out to ensure consistency with the simulated results. An extensive design of experiments is performed to obtain the optimum process parameters. The study demonstrates the potential of MMD to fabricate components with diverse geometrical configurations effectively. |
