Abstract

This study reviews the progress of using additive manufacturing (AM) for custom orthoses and prostheses (O&P) in the past 25 years. Foot orthoses (FOs), ankle-foot orthoses (AFOs), and prosthetic sockets are the most common types of O&P that are custom fabricated. A brief introduction to traditional plaster molding fabrication techniques for custom O&P are given for FO, AFO, and prosthetic sockets, followed by the AM process. Prior studies on AM of FOs, AFOs, and prosthetics sockets are reviewed. Applications of AM for other types of O&P are also presented. Lastly, future trends and challenges for adoption of AM for fabrication of O&P in clinical settings are discussed.

6. Trends and Future Challenges

This paper summarized the traditional and AM processes of custom FOs, AFOs, lower limb prosthetic sockets, and other applications in the past 25 years. In limited clinical evaluations, the AM technology has demonstrated the capability of fabricating custom FOs, AFOs, and lower limb prosthetic sockets with good fit and adequate strength. However, studies clearly show that there are clinical, technological (on both design and manufacturing), and financial barriers that need to be overcome before the AM technology can be adopted for full-scale implementation in a service system for custom O&P. While a number of research studies have been conducted for AM of O&P, major clinical facilities have not yet adopted AM for mass production of custom O&P. Several barriers need to be overcome in order to enable the adoption of AM in the orthotics and prosthetics industry. These barriers include: the lack of clinical and design interface for an AM system [11, 43], uneconomic throughput and material cost [12, 15], and limited material strength [41, 46].
