The additive manufacturing of ceramic components offers transformative opportunities for energy storage, biomedical implants, aerospace thermal protection, and microelectronic packaging. However, the strong coupling between processing conditions, multiscale microstructure, and final performance remains a persistent barrier to reliable industrial deployment. Machine learning has emerged as a powerful methodology for navigating this complexity, but its value depends on the broader system in which it is embedded. This paper presents a systems-oriented analysis of machine learning-enabled process-structure-property optimization for ceramic additive manufacturing. Rather than focusing narrowly on model accuracy, it examines the architectural, infrastructural, and governance dimensions required to integrate predictive models into materials development workflows. The paper reviews ceramic-specific process constraints, including rheology, debinding, drying, and sintering, and discusses how heterogeneous data from in situ sensing, characterization, and simulation can be organized into learning systems. Structural trade-offs are explored among model interpretability and predictive power, centralized and distributed data architectures, and short-term optimization and long-term robustness. The analysis extends to sustainability, fairness, and accountability concerns that arise when data-driven tools influence experimental design and industrial qualification. Policy implications are considered through emerging artificial intelligence governance frameworks. The paper argues that durable progress depends not only on better predictive models but also on institutional mechanisms, shared data protocols, and socio-technical safeguards. A holistic systems architecture can enable machine learning to support ceramic additive manufacturing from powder formulation and printing through microstructure control and property certification. This perspective connects materials informatics, advanced manufacturing, and responsible artificial intelligence governance for academic and industrial research communities.
