Abstract
Smart materials are vital for the rapid advancement of aerospace. To date, additive manufacturing (AM) has empowered the dynamic-stimuli-responsive bio-inspired and metamaterial structures of ceramic matrix composites (CMC) to achieve groundbreaking applications. Smart SiC composites, particularly those applied in extreme conditions of high temperature and load, as well as strong electromagnetic interference, have an urgent demand for development and application. The challenges such as poor powder flowability, limited densification, microcrack evolution, and unstable structural–electromagnetic coupling at high temperatures are still seriously affected both mechanical reliability and electromagnetic adaptability. Recent advances in powder modification, dopant engineering, and hierarchical microstructure design have improved sinter ability and impedance matching, while optimized process parameters and post-sintering treatments have enhanced strength and toughness. Meanwhile, digital twin–driven monitoring systems and in-situ sensing technologies offer new opportunities to establish adaptive feedback loops, enabling real-time correction of processing deviations and intelligent defect suppression. Furthermore, the synergistic interactions between innovative material design, process optimization, and real-time monitoring were discussed. A new integrative framework that connects raw material modification, process optimization, and online monitoring to enable high-quality AM of smart SiC composites was presented. It constitutes a comprehensive strategy for high-quality additive manufacturing of smart SiC composites, thereby paving the way for the advancement of smart materials.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
