A single- or multi-photon reactive composition comprises a liquid polysilazane precursor, a multifunctional acrylate additive, and a single- or multi-photon photocuring composition. The invention can be used to provide ceramic-based microstructures as, for example, high temperature resistant materials, including devices such as microcombustors, micro-heat-exchangers, sensor and actuator systems, microfluidic devices, and micro-optics systems that can be used independently or integrated into other systems.
