| Abstract Scope |
Molten Metal Jetting (MMJ) is a near-net shape additive manufacturing technology in which parts are built by successively adding droplets of molten metal onto a heated build platform. For functional surfaces, subtractive technologies such as milling may need to be used subsequently, raising questions about the residual stress state of the parts due to potential part warping. In this work, we used the hole-drilling method to investigate the residual stress state of parts fabricated from AlSi12 by MMJ under different thermal conditions. The results lead to the conclusion that in MMJ of aluminum, there is no pronounced residual-stress buildup and thus a low risk of residual-stress-induced warping during milling. |
