Summary Very high mortality rates of coronavirus pandemic (COVID‐19) are observed around the world due to lack of medical equipment. The increased need for medical devices and personal protective equipment (PPE) has kept several healthcare professionals at risk. Fortunately, 3D printing technology allows to overcome the lack of medical supplies. This study highlights the impact of 3D printing on the combat against COVID19, and its importance in the medical product supply chain. Indeed, the existing medical equipment fabricated by 3D printing technology and its role in the management of Covid19 pandemic is presented. Moreover, the last works are examined to know whether the models of the medical equipment are free of use and whether useful informations are presented (eg, available design data and setup guidelines).

“…The original and any follow-up scans or digital modifications can be preserved, providing a permanent record of a patient's limb [11,25]. In addition, it allows the use of a variety of materials for socket manufacturing, including antibacterial skin-safe filaments [48]. Despite such potential, 3D printing has been used primarily for grasping devices [20].…”

Modernising the way upper-limb prosthetic sockets are made has seen limited progress. The casting techniques that are employed in clinics today resemble those developed over 50 years ago and there is still a heavy reliance on manual labour. Modern manufacturing methods such as 3D scanning and printing are often presented as ready-to-use solutions for producing low-cost functional devices, with public perceptions being largely shaped by the superficial media representation and advertising. The promise is that modern socket manufacturing methods can improve patient satisfaction, decrease manufacturing times and reduce the workload in the clinic. However, the perception in the clinical community is that total conversion to digital methods in a clinical environment is not straightforward. Anecdotally, there is currently a disconnect between those developing technology to produce prosthetic devices and the actual needs of clinicians and people with limb difference. In this paper, we demonstrate strengths and drawbacks of a fully digitised, low-cost trans-radial diagnostic socket making process, informed by clinical expertise. We present volunteer feedback on the digitally created sockets and provide expert commentary on the use of digital tools in upper-limb socket manufacturing. We show that it is possible to utilise 3D scanning and printing, but only if the process is informed by expert knowledge. We bring examples to demonstrate how and why the process may go wrong. Finally, we provide discussion on why progress in modernising the manufacturing of upper-limb sockets has been slow yet it is still too early to rule out digital methods.

“…Recent developments and applications in biomechanics introduced the utilization of a three-dimensional (3D) printing system to enhance the process of socket design. As reported by Zuniga [3], 3D printers have been utilized to develop prosthetic devices using antibacterial filaments. The investigation found that the 3D printer is capable of developing effective antibacterial finger prosthesis.…”

“…According to Nguyen et al [4], the design and 3D printing of the transfemoral prosthetic socket required less time compared to conventional methods. However, the evaluation for 3D printing prefabrication has not been discussed in most of the previously published research studies [3,[5][6][7].…”

Development of an Evaluation System for Magnetic Resonance Imaging Based Three-Dimensional Modeling of a Transfemoral Prosthetic Socket Using Finite Elements

et al. 2019

Recent technologies have suggested the utilization of three-dimensional (3D) printing technology to enhance the fabrication accuracy of prosthetics. Accordingly, simulations are used to obtain precise parameters for subject-specified prosthetic socket. This study proposes an evaluation system to measure the accuracy of a subject-specific 3D transfemoral residuum model during the interaction with the socket in conjunction with the application of finite element methods. The proposed system can be used in future validations of socket fabrication. The evaluation is based on the measurement of the residuum’s soft tissue deformation inside two types of prosthetic sockets. In comparison with other studies, the 3D models were constructed with magnetic resonance images (MRI) with the aid of computer-aided design (CAD) software. The measurement of soft tissue deformation was conducted based on the measurement of the volumetric value of fat, muscle and skin in the pre- and post-donning phases. The result yielded a promising correlation coefficient value between the simulation and the experiment in the soft tissue deformation evaluation. The relation of the muscle–fat ratio in the residuum is extremely important in the determination of the ability of the prosthetic to deform. The environment during the socket fitting session was similar to that defined by the set boundary conditions in simulations. In view of the promising results of this study, the evaluation system proposed herein is considered reliable and is envisaged to be used in future research.
