The present disclosure relates to systems, methods and resins for additive manufacturing. In one embodiment, a method for additive manufacturing of a ceramic structure includes providing a resin including a preceramic polymer and inorganic ceramic filler particles dispersed in the preceramic polymer. The preceramic polymer is configured to convert to a ceramic phase. The method includes functionalizing inorganic ceramic filler particles with a reactive group and applying an energy source to the resin to create at least one layer of the ceramic phase from the resin.
