"This book presents a structured and comprehensive overview of digital technologies and additive manufacturing techniques applied in prosthetics and orthotics. It traces the transition from traditional fabrication methods to modern digital workflows, emphasizing the role of 3D scanning, computer-aided design, additive and subtractive manufacturing in achieving patient-specific solutions. Fundamental concepts, process classifications, materials, equipment, and design considerations are explained using clear illustrations, tables, practical examples, exam-oriented questions, and real-world manufacturing perspectives to enhance learning and application. The content is aligned with the prescribed syllabus of the Rehabilitation Council of India (RCI). Most existing textbooks in prosthetics and orthotics primarily focus on traditional fabrication techniques, while books on digital fabrication tend to be engineering-oriented or limited to CAD/CAM concepts without adequate clinical integration. As a result, there is a lack of a dedicated resource that comprehensively explains CAD/CAM, 3D scanning and digital assessment, additive manufacturing, clinical fitting, and outcome evaluation within a unified framework. This book addresses this gap by integrating digital technologies with clinical prosthetic and orthotic practice, providing a complete guide from design to clinical application."
