Abstract:	Additive manufacturing enables the introduction of new shaping concepts, not only through direct printing of ceramic green bodies, but also through the production of molds. The particular advantage of the almost unlimited geometry complexity of additive manufacturing unfolds when soluble molds are used. This can be used to produce undercut shapes, threads, channels, and other otherwise complicated shape elements. The use of molds instead of direct 3D printing of ceramic green bodies offers the opportunity to circumvent existing limitations of currently available technologies and materials. For example, direct printing using DLP (digital light processing) processes is limited by the optical properties of raw materials and by the properties of available resins. Even fewer ceramic/thermoplastic filaments are commercially available for the FDM (fused deposition modeling) process. These limitations can be circumvented by printing the molds using DLP and filling and curing them with ceramic materials, e.g. as thermoplastic feedstocks in injection molding or as thermosetting gelcasting slurries. Subsequently, the mold is dissolved in solvents, but preferably in water, and a precisely molded green body is obtained. A similar material concept can of course also be used for the production of soluble support structures in 3D printing. A wide variety of examples for the use of soluble molds and support structures in DLP or FDM processes will be presented.
