3D Printing Technologies and Materials for Prosthetics and Orthotics

The integration of 3D printing technologies in the field of prosthetics and orthotics has ushered in a new era of customisation, accessibility and innovation. This book chapter provides an in-depth exploration of the diverse range of 3D printing technologies and materials utilised for the fabrication of prosthetic and orthotic devices. Beginning with an overview of the fundamental principles underlying 3D printing processes such as fused deposition modelling (FDM), stereolithography (SLA), selective laser sintering (SLS), and binder jetting, the chapter elucidates their respective strengths, limitations and applications in the context of prosthetic and orthotic design and production. Furthermore, it examines the crucial role of materials selection in achieving optimal performance, comfort and durability of prosthetic and orthotic devices, discussing the properties and characteristics of commonly used materials such as thermoplastics, metals and biocompatible polymers. Additionally, the chapter explores advancements in additive manufacturing techniques, including multi-material printing and 4D printing, and their potential to enhance the functionality and adaptability of prosthetic and orthotic solutions. Through case studies and real-world examples, the chapter showcases the transformative impact of 3D printing technologies on improving patient outcomes, reducing production costs and accelerating the customisation process in the field of prosthetics and orthotics. By offering insights into the latest advancements and best practices, this chapter serves as a valuable resource for researchers, clinicians and practitioners seeking to harness the full potential of 3D printing for the development of next-generation prosthetic and orthotic solutions.
