Implementation of Additive Manufacturing Workflows into the Prosthetic & Orthotic Industry: Case Study

Abstract

The prosthetic and orthotic industry is evolving to include innovative technologies as solutions to material and labour usage, promoting more sustainable and cleanly practises for both staff and patients. 3D printing, scanning and software have revolutionised the workflows of clinicians, technicians and administrative staff. To determine the reliability and repeatability of additive manufacturing (AM) workflows in a P&O company, observation and interview analyses were undertaken within an established prosthetic and orthotic company. The collection of data from these opportunities offered valuable insight into workflow sessions, employee feedback and predetermined themes regarding both traditional and AM processes for the production of Transtibial prosthetic sockets. Findings revealed the reduction in workflow sessions, technician resource and storage requirements when working through AM processes, although there is a lack of opportunity and resource for clinicians and technicians to learn how to use these digitalised processes. Although both traditional and 3D printed sockets receive similar feedback from patients regarding comfort and fit, discrepancies in socket weight were noted. A further understanding on the culture and adoption barriers of AM processes should be investigated for clinicians, technicians and administrative staff across a larger sample size.
