There is a trend toward more performant materials with the objective to improve the efficiency of actual systems and to repel technological boundaries. Carbides can be considered as such strategic materials. Inherent difficulties to the traditional techniques for manufacturing such materials with a complex geometry can be overcome by the development of new manufacturing approaches on the first hand, and the deployment of synthetic paths. This second part can be investigated by the Polymer-Derived Ceramics (PDCs) route, which offers new opportunities in ceramic sciences. Here, the aim of this work is to modify SiC precursors to fit in Fused Deposition Modeling technology and design SiC-based components with complex shapes at relatively low temperature. The chemistry behind the synthesis and pyrolysis behaviour of these polymers as well as their processability will be presented and discussed. The characterization of the materials will be done at each step of their elaboration process.
