“…Several studies have been conducted on incorporating AM into socket design and advancement to address the issues of a transtibial amputee. Because of the low cost of printing, FDM is a common fabrication technique for prosthesis sockets (Lu et al , 2009; Moulic et al , 2019; van der Stelt et al , 2021). Traditional transtibial prosthesis design and manufacturing time vary between 5 and 14 days, including measurements (one day), mold creation (one to three days), socket creation (two to six days), assembly, alignment, fitting and cosmetic finish (one to four days).…”

Purpose Medical devices are undergoing rapid changes because of the increasing affordability of advanced technologies like additive manufacturing (AM) and three-dimensional scanning. New avenues are available for providing solutions and comfort that were not previously conceivable. The purpose of this paper is to provide a comprehensive review of the research on developing prostheses using AM to understand the opportunities and challenges in the domain. Various studies on prosthesis development using AM are investigated to explore the scope of integration of AM in prostheses development. Design/methodology/approach A review of key publications from the past two decades was conducted. Integration of AM and prostheses development is reviewed from the technologies, materials and functionality point of view to identify challenges, opportunities and future scope. Findings AM in prostheses provides superior physical and cognitive ergonomics and reduced cost and delivery time. Patient-specific, lightweight solutions for complex designs improve comfort, functionality and clinical outcomes. Compared to existing procedures and methodologies, using AM technologies in prosthetics could benefit a large population. Originality/value This paper helps investigate the impact of AM and related technology in the field of prosthetics and can also be viewed as a collection of relevant medical research and findings.

“…As in any layer manufacturing process, the strength of the FDM socket depends on how well one layer of material is bonded to another. FDM printed prosthetic leg sockets are rarely made, and limited research has been performed regarding the strength, comfort and long-term tear, and wear of these devices [24][25][26]. In an earlier study, the strength of these low-cost 3D-printed transtibial prosthetic sockets was investigated and evaluated [27].…”

Pioneering low-cost 3D-printed transtibial prosthetics to serve a rural population in Sierra Leone – an observational cohort study

et al. 2021

Background: There is a huge unmet global need for affordable prostheses. Amputations often happen in Sierra Leone due to serious infections, complex wounds, traffic accidents and delayed patient presentation to the hospital. However, purchasing a prosthesis is still beyond reach for most Sierra Leonean amputees. Method: We applied computer-aided design (CAD) and computer-aided manufacturing (CAM) to produce low-cost transtibial prosthetic sockets. In February and March 2020, eight participants received a 3D printed transtibial prosthesis in the village of Masanga in Tonkolili district, Sierra Leone. Research was performed using questionnaires to investigate the use, participants' satisfaction, and possible complications related to the prostheses. Questionnaires were conducted prior to production of the prosthesis and five to six weeks after fitting the prosthesis. A personal short-term goal was set by the participants. Findings: Competitively priced and fully functional prostheses were produced locally. After six weeks, all participants were still wearing the prosthesis and six of the eight participants reached their personal rehabilitation goals. Using their prostheses, all participants were no longer in need of their crutches. Interpretation: We have come a step closer to the production of low-cost prostheses for low-and middleincome countries (LMICs). The goal of our project is to perform long-term follow-up and to refine our concept of 3D printed prostheses for LMICs to provide practical solutions for a global health need unmet to date. Funding: € 15,000 was collected during a crowdfunding campaign in collaboration with the Dutch Albert Schweitzer Fund. Internship allowance for MvdS was obtained from the University of Twente. 3D-scanner, 3D-printer, and printing material were donated by Ultimaker BV and Shining 3D.
