| Abstract Scope |
Liquid metal jetting (LMJ) bears the potential of being a fast part manufacturing technology while using a cheap raw material. LMJ is a subtype of material jetting (MJT) and the parts are built by successively depositing droplets of molten metal onto a build platform. For full 3D capability, support structures are necessary which must be removed in subsequent processes. In previous investigations, we proposed the usage of water-soluble salt as a support material, selected a suitable salt, and analyzed the influence of this material on aluminum parts made in LMJ. In the present work, we show a duplex MJT print head for the processing of aluminum alloys and KCl-NaCl salt. Various printing strategies and support structure types are compared. The results show that the sequence of printing aluminum and salt is crucial. Furthermore, the use of thin layers of support material as a release layer appears promising. |
