ABSTRACT
Embedding sensors into carrier parts is of great significance for in-suit monitoring of industrial
processes. In this study, a new extrusion free-forming process for ceramic parts was developed. In this
process, Aqueous–based ceramic paste extrusion is extruded at room temperature with side evaporation
prohibited by oil. A new tool path planning program for this process was developed to overcome the
limitations of existing tool path planning software. The capability of fabricating solid ceramic parts was
demonstrated by embedding several sensors using this process. Among the optical fiber samples
embedded in this process, silica fibers were damaged due to the high sintering temperature. Sapphire
fibers survived the whole fabrication process and it was validated by optical test.
