Abstract Scope |
Molten Metal Jetting (MMJ) is an additive manufacturing technology for fabricating metal parts without the need for powder feedstock. The raw material is melted and ejected dropwise onto a build platform, whereby support structures are necessary for realizing arbitrary shapes. Recently, the jetting of molten salts for fabricating water-soluble support structures for MMJ has been developed and integrated into the process. In another work, an automated multi-material simulation environment has been set up to evaluate the thermal history during the printing of both metal and salt. In this work, the processing of aluminum parts with salt support structures is investigated on sample geometries, using AlSi12 as build material and a mixture of KCl and NaCl as support material. The results show that the part build-up strategy greatly influences the thermal history of the droplets and, thus, the mechanical properties of parts, opening a way for local part property modification. |
