Purpose The purpose of this paper is to investigate the phenomenon of the digital do-it-yourself (DiDIY) in the medical domain. In particular, the main contribution of the paper is the analysis and discussion of a questionnaire-based user study focused on 3D printing (3DP) technology, which was conducted among clinicians of one of the most important research hospital group in Lombardy, Italy. Design/methodology/approach A general reflection on the notion of knowledge artifacts (KAs) and on the use of 3DP in medicine is followed by the research questions and by a more detailed analysis of the specialist literature on the usage of 3DP technology for diagnostic, training and surgical planning activities for clinicians and patients. The questionnaire-based user study design is then emerging from the conceptual framework for DiDIY in healthcare. To help focus on the main actors and assets composing the 3DP innovation roles in healthcare, the authors model: the DiDIY-er as the main initiator of the practice innovation; the available technology allowing the envisioning of new practices; the specific activities gaining benefits from the innovative techniques introduced; and the knowledge community continuously supporting and evolving knowledge practices. Findings The authors discuss the results of the user study in the light of the four main components of our DiDIY framework and on the notion of KA. There are differences between high expertise, or senior, medical doctors (MDs) and relatively lower expertise MDs, or younger MDs, regarding the willing to acquire 3DP competences; those who have seen other colleagues using 3DP are significantly more in favor of 3DP adoption in medical practices, and those who wish to acquire 3DP competence and do-by-themselves are significantly more interested in the making of custom-made patient-specific tools, such as cutting guides and templates; there are many recurrent themes regarding how 3DP usage and application may improve medical practice. In each of the free-text questions, there were comments regarding the impact of 3DP on medical knowledge practices, such as surgical rehearsal, surgery, pathology comprehension, patient-physician communication and teaching. Originality/value The 3DP adoption in healthcare is seen favorably and advocated by most of the respondents. In this domain, 3DP objects can be considered KAs legitimately. They can support knowledgeable practices, promote knowledge sharing and circulation in the healthcare community, as well as contribute to their improvement by the introduction of a new DiDIY mindset in the everyday work of MDs.

Purpose The purpose of this paper is to describe a novel design workflow for the digital fabrication of custom-made orthoses (CMIO). It is intended to provide an easier process for clinical practitioners and orthotic technicians alike. It further functions to reduce the dependency of the operators’ abilities and skills. Design/methodology/approach The technical assessment covers low-cost three-dimensional (3D) scanning, free computer-aided design (CAD) software, and desktop 3D printing and acetone vapour finishing. To analyse its viability, a cost comparison was carried out between the proposed workflow and the traditional CMIO manufacture method. Findings The results show that the proposed workflow is a technically feasible and cost-effective solution to improve upon the traditional process of design and manufacture of custom-made static trapeziometacarpal (TMC) orthoses. Further studies are needed for ensuring a clinically feasible approach and for estimating the efficacy of the method for the recovery process in patients. Social implications The feasibility of the process increases the impact of the study, as the great accessibility to this type of 3D printers makes the digital fabrication method easier to be adopted by operators. Originality/value Although some research has been conducted on digital fabrication of CMIO, few studies have investigated the use of desktop 3D printing in any systematic way. This study provides a first step in the exploration of a new design workflow using low-cost digital fabrication tools combined with non-manual finishing.

Purpose The purpose of this paper is to focus on the profile of DiDIYers and the antecedents of digital do it yourself (DiDIY) in Network Marketing Direct Selling Organizations (NMDSO). Design/methodology/approach A two-step research design allowed the detection of DiDIYers strictu sensu (i.e. digital makers). After collecting data about the attitudes and the actual use of digital technology (DT) by network marketers through an online survey, an open-ended interview technique made it possible to analyze the personal characteristics of DiDIYers, the motivations that drive them and the activities that mainly foster the creation of artifacts in the DT domain. Besides, it allowed to recognize the perceived benefits and the impact of DiDIY output on networkers’ downline and firms’ performance. Findings The results provide a preliminary profile of the DiDIYer in network marketing communities that is suitable for further comparative studies. More specifically, this exploratory study acknowledges the most important antecedents of DiDIY in digital literacy – including the awareness of being a digital literate and/or a potential appropriateur – and in organizational culture. Research limitations/implications This is an exploratory study based on a limited sample of DiDIYers, nevertheless it offers a preliminary view of the subjective side of the DiDIY phenomenon in network marketing and represents as well a context-bound study. Practical implications Considering the ascribed benefits of DiDIY output on the traditional network marketing objectives (effectiveness, efficiency, cohesion, mutual assistance and reinforcement) network marketing communities could benefit from an increase of attention to the topic. Originality/value The study throws light on the process of DiDIY within direct sales and network marketing activities by defining a preliminary profile of digital makers and thus, underlining a phenomenon neglected so far.

Purpose This case study aims to demonstrate how the Greater Leadership Opportunities for Women (GLOW) Mayo Clinic Employee Resource Groups (MERG) has positively impacted leadership development focusing on growth, resilience, inspiration and tenacity (GRIT) and increased advancement for female leaders at Mayo Clinic. It will also establish how the innovative utilization of employee resource groups can positively impact the development of leaders within an institution in general and specially can enhance behaviors related to GRIT. Design/methodology/approach This case study design was used to measure the impact of the GLOW MERG’s interventions through qualitative and quantitative approaches that highlight both process and outcome to increase study validity through complementarity, which “seeks elaboration, enhancement, illustration, clarification of the results from one method with the results from another” (Greene, et al., 1989, p. 259) as well as completeness and context (Onghena et al., 2019; Schoonenboom and Johnson, 2017; Bryman, 2006). Learning outcomes (knowledge), skill accomplishments and attitude development were evaluated within two weeks after each session and annually through standardized surveys sent to participants via email. The surveys were designed to capture key information about the sessions, including the impact of the session content, the willingness and ability of attendees to apply the learning and identification of opportunities for improvement in session design and delivery, as well as measure satisfaction with the activities offered, the frequency and method(s) of communication, barriers to session attendance and particular topics or speakers of interest to members (Appendix 1). Response options included dichotomous scales, Likert-type scales, multi-select and free text. This provided a voluntary response sampling, as post-session surveys were sent to all session attendees and annual surveys were sent to all GLOW MERG members, which allowed individuals to choose if they would respond to the surveys (Creswell and Creswell, 2018). To foster an environment of continuous improvement, plan-do-study-act (PDSA) cycles (Langley et al., 2009) were conducted after every survey by the event planning team and the GLOW MERG Board. Interventions were tested, reviewed and discussed during monthly board meetings and event planning. Improvements were made and results were shared with key stakeholders through regular communication channels. Additionally, 30 past and present GLOW MERG leaders were surveyed to measure their perceived impact of participation in the GLOW MERG interventions using dichotomous scales, multi-select and free text responses (Appendix 2). This targeted purposive sample was selected because of their high level of engagement with the MERG to provide a retrospective evaluation of the success of the GLOW MERG, and its interventions for career advancement related to the development of GRIT attributes, knowledge and skills resulting in career advancement for those who are/have been highly engaged with the MERG. Findings The results spanning the past few years of GLOW MERG interventions has shown that the GLOW MERG has been successful in providing targeted educational events that address the GRIT knowledge, skills and attributes, needed for female health-care leaders to be successful in developing GRIT capabilities. By staying true to its mission and vision, the GLOW MERG has been able to promote, educate and empower female leaders at Mayo Clinic while actively breaking down the barriers that can prevent women from obtaining leadership positions. Research limitations/implications There are several limitations with this case study’s data collection and sampling methods. First, the post-session and annual survey sampling was based mainly on ease of access, with responses obtained from respondents who are more likely to volunteer or those with the strongest opinions. This allowed for potential bias as responses may not be representative of all GLOW MERG member opinions. Furthermore, the purposive sample of present and past GLOW MERG leaders was also subject to volunteer bias and may not have be representative of the GLOW MERG population. Additionally, the case study examined the practices of only one site and MERG group and may not be representative of all sites or employee resources groups. Practical implications The interventions implemented by the GLOW MERG to assist women with developing GRIT knowledge, skills and attributes – barriers women often face in leadership roles – were tested, reviewed and discussed during monthly board meetings and event planning. PDSA cycles were conducted, improvements were made and results were shared with key stakeholders through regular communication channels (Langley et al., 2009). Key lessons learned from these assessments include: One size does not fit all for leadership development. GLOW members have a wide variety of backgrounds, skills and experiences. Repetition is important in the development of GRIT knowledge, skills and attributes associated with GRIT. A one-time event provides attendees with an information overview and the steps to start developing a new skill but no dedicated time to practice and implement that skill. Originality/value The innovative utilization of employee resource groups can positively impact the development of leaders within an institution in general and specially can enhance behaviors related to GRIT.

Purpose This paper aims to examine the floating dry dock and 3D printing technologies in relation to the ways in which they have the potential to complement each other. This relates to how the tourism and maritime industries in Jamaica could become more robust and competitive. Design/methodology/approach This study used a qualitative approach through the application of personal interviews and data from secondary sources. Findings Although Jamaica is positioning itself to become one of the leading maritime and logistics centres in the world, the government has not fully taken advantage of the fourth industrial revolution and its enabling factors. The integration of the floating dry dock with 3D printing technology has the ability to advance Jamaica from its current position to become a more economically viable country. Research limitations/implications Time was a limitation for the researchers in conducting this study. As a result, a more robust field study is needed to fully understand the impact of the fourth industrial revolution technologies on the maritime and tourism industries. Practical implications An investment in a floating dry dock and 3D printing technology will spur job creation. The researchers expect improved economic activity in Jamaica resulting from many businesses being created and/or improved. Social implications The quality of life is expected to increase because of the greater economic yields the country will receive from such investments. Originality/value This paper explored the combination of the floating dry dock and 3D printing technologies and their impact on the tourism and maritime industries in relation to increasing service value and economic yields.

Purpose Nowadays, there is a high demand for online services and applications. However, there is a challenge to keep these applications secured by applying different methods rather than using the traditional approaches such as passwords and usernames. Keystroke dynamics is one of the alternative authentication methods that provide high level of security in which the used keyboard plays an important role in the recognition accuracy. To guarantee the robustness of a system in different practical situations, there is a need to examine how much the performance of the system is affected by changing the keyboard layout. This paper aims to investigate the impact of using different keyboards on the recognition accuracy for Arabic free-text typing. Design/methodology/approach To evaluate how much the performance of the system is affected by changing the keyboard layout, an experimental study is conducted by using two different keyboards which are a Mac’s keyboard and an HP’s keyboard. Findings By using the Mac’s keyboard, the results showed that the false rejection rate (FRR) was 0.20, whilst the false acceptance rate (FAR) was 0.44. However, these values have changed when using the HP’s keyboard where the FRR was equal to 0.08 and the FAR was equal to 0.60. Research limitations/implications The number of participants in the experiment, as the authors were targeting much more participants. Originality/value These results showed for the first time the impact of the keyboards on the system’s performance regarding the recognition accuracy when using Arabic free-text.

Purpose The purpose of this paper is to examine the impact of three-dimensional (3D)-printing process settings (particularly print orientation) on the tribological properties of different polymers. Design/methodology/approach In this study, fused deposition modelling 3D-printing technology was used for fabricating the specimens. To evaluate the influence of print orientation, the test pieces were manufactured horizontally (X) and vertically (Z). The tribological properties of various printed polymers, which are polylactide acid, high tensile/high temperature-polylactide acid and polyethylene terephthalate-glycol have been studied. The tribological tests have been carried out under reciprocating sliding and dry condition. Findings The results show that the presence of various orientations during the 3D-printing process makes a difference in the coefficient of friction and the wear depth values. Findings suggest that printing structure in the horizontal orientation (X) assists in reducing friction and wear. Originality/value To date, there has been very limited research on the tribology of objects produced by 3D printing. This work was made as an attempt to pave the way for future research on the science of tribology of 3D-printed polymers.

Purpose This paper aims to focus on the development of the three-dimensional (3D) printing filaments based on acrylonitrile butadiene styrene (ABS) copolymer and styrene-ethylene/butylene-styrene (SEBS) block copolymer, with tailored viscoelastic properties and controlled flow during the 3D printing process. Design/methodology/approach In this investigation, ABS was blended with various amounts of SEBS via a melt mixing process. Then the ABS/SEBS filaments were prepared by a single-screw extruder and printed by the FDM method. The rheological properties were determined using an MCR 501 from Anton-Paar. The melt flow behavior of ABS/SEBS filaments was determined. The morphology of the filaments was studied by scanning electron microscope and the mechanical (tensile and impact) properties, surface roughness and void content of printed samples were investigated. Findings The rheological results can accurately interpret what drives the morphology and mechanical properties’ changes in the blends. The impact strength, toughness, elongation-at-break and anisotropy in mechanical properties of ABS samples were improved concurrently by adding 40 Wt.% of SEBS. The optimal tensile properties of blend containing 40 Wt.% SEBS samples were obtained at −45°/+45° raster angle, 0.05 mm layer thickness and XYZ build orientation. Optimized samples showed an 890% increase in elongation compared to neat ABS. Also, the impact strength of ABS samples showed a 60% improvement by adding 40 Wt.% SEBS. Originality/value The paper simultaneously evaluates the effects of material composition and 3D printing parameters (layer thickness, raster angle and build orientation) on the rheology, morphology, mechanical properties and surface roughness. Also, a mechanical properties comparison between printed samples and their compression-molded counterpart was conducted.

Cardiovascular diseases are the leading cause of mortality worldwide. Given the limited endogenous regenerative capabilities of cardiac tissue, patient-specific anatomy, challenges in treatment options, and shortage of donor tissues for transplantation, there is an urgent need for novel approaches in cardiac tissue repair. 3D bioprinting is a technology based on additive manufacturing which allows for the design of precisely controlled and spatially organized structures, which could possibly lead to solutions in cardiac tissue repair. In this review, we describe the basic morphological and physiological specifics of the heart and cardiac tissues and introduce the readers to the fundamental principles underlying 3D printing technology and some of the materials/approaches which have been used to date for cardiac repair. By summarizing recent progress in 3D printing of cardiac tissue and valves with respect to the key features of cardiovascular tissue (such as contractility, conductivity, and vascularization), we highlight how 3D printing can facilitate surgical planning and provide custom-fit implants and properties that match those from the native heart. Finally, we also discuss the suitability of this technology in the design and fabrication of custom-made devices intended for the maturation of the cardiac tissue, a process that has been shown to increase the viability of implants. Altogether this review shows that 3D printing and bioprinting are versatile and highly modulative technologies with wide applications in cardiac regeneration and beyond.
