Abstract Scope |
This talk reviews the different approaches for the additive manufacturing of ceramics and discusses how preceramic polymers can offer new opportunities from high temperature applications to microelectronics. Siloxane and carbosilane organo-silicon polymers will convert to Si(O)C upon pyrolysis. We have developed UV curable variants for use with liquid-vat type 3D printers as well as shear-thickening variants for direct ink writing. Suspending fibers or particles in the resin before printing results in a two-phase microstructure in the pyrolyzed part. This enables additive manufacturing of SiC based ceramic matrix composites that exhibit high strength at 1600°C. Furthermore, the low viscosity of preceramic resins is advantageous for additive micro-manufacturing of parts on the centimeter scale with 10 µm sized features. We demonstrate thousands of curved holes (i.e., vias) – printed directly into the ceramic – that can be subsequently metallized to provide electric pathways. This technology enables unprecedented via routing and packaging options for the 3D integration of microelectronic subsystems. |
