Additive Manufacturing of Polymer Composites: Technologies, Materials, and Applications provides a comprehensive and multidisciplinary exploration of the intersection between additive manufacturing (AM) and polymer matrix composites (PMCs). Its primary objective is to bridge the knowledge gap between AM technologies and polymer composites, delivering an integrated perspective that encompasses fundamental principles, material selection, process optimization, technological advancements, and emerging applications. The book&s timely significance is highlighted by the rapidly evolving use of AM to fabricate lightweight, high-performance composites for sectors such as aerospace, automotive, medical devices, and industrial tooling. It covers new developments such as smart composites, 4D printing, and AI-driven process optimization-areas not yet fully addressed in the current literature. The book&s content structure follows a logical progression: it begins with a foundational overview of AM and PMCs, explores materials and their properties, examines technological processes and process parameter optimization, and then addresses advanced characterization, quality control, and applications. Future perspectives, including sustainability, smart materials, and digital innovations, are also included. Key themes include material-process integration, quality assurance, sustainability, and the application of AM-PMCs in complex engineering contexts. Includes standardization and certification of AM composites Expanded sections on AI/machine learning in process optimization Covers detailed modeling and simulation (including predictive modeling) Includes economic feasibility and industrial scalability Covers life cycle assessment, sustainable materials, and recycling strategies Includes experimental validation techniques
