“…This information is crucial for the implementation of 3D printed prostheses as post-operative or transitional prostheses. Based on previous investigations [11][12][13][14][16][17][18][19], we hypothesized that (i) antibacterial 3D printed filaments can be used for the development of functional upper-limb prostheses and (ii) the antibacterial properties of the 3D printing filament after extrusion and development of the prosthesis do not affect the antibacterial properties of the filament.…”

The purpose of the current investigation was two-fold: (i) to describe the development of 3D printed prostheses using antibacterial filaments and (ii) to verify the antibacterial properties of the 3D printed prostheses. Three-dimensional printed finger prostheses were manufactured using PLACTIVETM antibacterial 3D printing filaments. Two adults with left index finger amputations at the proximal phalanx were fitted with a customized 3D printed finger prosthesis manufactured with an antibacterial filament. The manual gross dexterity was assessed during the Box and Block Test. Patient satisfaction was assessed using the Quebec User Evaluation of Satisfaction with assistive Technology (QUEST 2.0). Bacterial analysis of the 3D printed prostheses was performed by two independent laboratories against Staphylococcus aureus and Escherichia coli (ISO 22196). Two customized 3D printed partial finger prostheses were manufactured using a 3D printed antibacterial filament. The bacterial analysis showed that PLACTIVETM with 1% antibacterial nanoparticles additives was up to 99.99% effective against Staphylococcus aureus and Escherichia coli. The manual gross dexterity assessed was improved after using the 3D printed partial finger prosthesis. The research subjects indicated that they were “quite satisfied” to “very satisfied” with the 3D printed partial finger prosthesis. The present investigation showed that the antibacterial 3D printed filament can be used for the development of functional and effective antibacterial finger prostheses.

“…To deepen our understanding of the long-term effects of 3D-printed myoelectric prostheses in upper-limb amputees, we adopted the OPUS-UEFS to assess the potential of a 3D-printed myoelectric prosthesis created with a lower price or a nonprofit goal in mind for enhancing prosthesis dexterity and quality of life. A previous study investigated a 3D-printed body-powered prosthesis and changes in manual dexterity using the box and block test with 2 years of follow-up [19]. However, there is no previous study on a 3D-printed myoelectrical hand prosthesis with a clinical evaluation of patient-reported outcomes.…”

Background Prosthetic hands with a myoelectric interface have recently received interest within the broader category of hand prostheses, but their high cost is a major barrier to use. Modern three-dimensional (3D) printing technology has enabled more widespread development and cost-effectiveness in the field of prostheses. The objective of the present study was to evaluate the clinical impact of a low-cost 3D-printed myoelectric-interface prosthetic hand on patients' daily life. Methods A prospective review of all upper-arm transradial amputation amputees who used 3D-printed myoelectric interface prostheses (Mark V) between January 2016 and August 2017 was conducted. The functional outcomes of prosthesis usage over a 3-month follow-up period were measured using a validated method (Orthotics Prosthetics User Survey-Upper Extremity Functional Status [OPUS-UEFS]). In addition, the correlation between the length of the amputated radius and changes in OPUS-UEFS scores was analyzed. Results Ten patients were included in the study. After use of the 3D-printed myoelectric single electromyography channel prosthesis for 3 months, the average OPUS-UEFS score significantly increased from 45.50 to 60.10. The Spearman correlation coefficient (r) of the correlation between radius length and OPUS-UEFS at the 3rd month of prosthetic use was 0.815. Conclusions This low-cost 3D-printed myoelectric-interface prosthetic hand with a single reliable myoelectrical signal shows the potential to positively impact amputees' quality of life through daily usage. The emergence of a low-cost 3D-printed myoelectric prosthesis could lead to new market trends, with such a device gaining popularity via reduced production costs and increased market demand.

“…Only one 3D-printed hand reports comparable force measurements over the fingertips (3.9–11.5 N), 33 and only one study presents results of a SHAP test on a 3D-printed hand, 34 not reporting, however, IOF scores. Just another study performs a BBT on a 3D-printed hand (Cyborg beast; 13 ± 12.7 blocks) scoring similarly to our 3D-printed non-assembly hand, 35 although our design performs better in comparison when using friction enhancements over the finger pads. Interestingly, Zuniga et al’s 35,36 study is one of the few that provides other clinical metrics like range of motion or wrist strength.…”

In developing countries, the access of amputees to prosthetic devices is very limited. In a way to increase accessibility of prosthetic hands, we have recently developed a new approach for the design and 3D printing of non-assembly active hand prostheses using inexpensive 3D printers working on the basis of material extrusion technology. This article describes the design of our novel 3D-printed hand prosthesis and also shows the mechanical and functional evaluation in view of its future use in developing countries. We have fabricated a hand prosthesis using 3D printing technology and a non-assembly design approach that reaches certain level of functionality. The mechanical resistance of critical parts, the mechanical performance, and the functionality of a non-assembly 3D-printed hand prosthesis were assessed. The mechanical configuration used in the hand prosthesis is able to withstand typical actuation forces delivered by prosthetic users. Moreover, the activation forces and the energy required for a closing cycle are considerably lower as compared to other body-powered prostheses. The non-assembly design achieved a comparable level of functionality with respect to other body-powered alternatives. We consider this prosthetic hand a valuable option for people with arm defects in developing countries.
