dc.description.abstractThe cost and time-intense mold making often limits widespread use of ceramic injection molding (CIM), especially during the prototyping phase of a project, when multiple iterations of design, fabrication and testing are required. We seek to speed up prototyping by 3D printing water-soluble sacrificial molds by fused deposition modeling (FDM) from polyvinyl alcohol (PVA) or digital light processing (DLP) from water-soluble resin. Furthermore, sacrificial molds enable more design freedom and complex geometries since limitations concerning undercuts do not apply. The method was used to injection mold parts with various geometries from commercial Al2O3 feedstock as well as ceramic heating elements in different shapes. The heating elements were produced from a ceramic composite feedstock containing conductive MoSi2, Al2O3 and feldspar. A comparison between molds printed from FDM and DLP revealed that DLP is better suited for parts with fine structures due to the higher resolution of DLP. Furthermore, the method was extended to two-component CIM on two examples of a ceramic crucible with integrated ceramic heating coil as well as a heating element with zones of different electrical conductivity.de_CH
