Fused Filament Fabrication of Small Ceramic Components
With respect to rapid prototyping of ceramic components, there are known only a few processes (stereo lithography, binder jetting) In this work, a new process chain is described in detail, showing that ceramics can be printed in a very cost efficient way. We developed a ceramic polymer composite as filament material that can be printed on a low cost fused filament fabrication (FFF) desktop printer, even with very small nozzle sizes enabling very small geometric feature sizes. The thermal post processing, with debinding and sintering, is very close to the ceramic injection molding (CIM) process chain.
