The eruption of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (corona virus disease, COVID-19) in Wuhan, China, and its global spread has led to an exponentially growing number of infected patients, currently exceeding over 6.6 million and over 390,000 deaths as of the 5th of June 2020. In this pandemic situation, health systems have been put under stress, and the demand for personal protective equipment (PPE) exceeded the delivery capabilities of suppliers. To address this issue, 3D printing was identified as a possible solution to quickly produce PPE items such as face shields, mask straps, masks, valves, and ear savers. Around the world, companies, universities, research institutions, and private individuals/hobbyists stepped into the void, using their 3D printers to support hospitals, doctors, nursing homes, and even refugee camps by providing them with PPE. In Germany, the makervsvirus movement took up the challenge and connected thousands of end users, makers, companies, and logistic providers for the production and supply of face shields, protective masks, and ear savers. The Karlsruhe Institute of Technology (KIT) also joined the makervsvirus movement and used its facilities to print headbands for face shield assemblies and ear savers. Within this paper, the challenges and lessons learned from the quick ramp up of a research laboratory to a production site for medium-sized batches of PPE, the limitations in material supply, selection criteria for suitable models, quality measures, and future prospects are reported and conclusions drawn.

In addition to their ability to reach distant learners, interactive e-learning environments have the potential to make the teaching-learning process more effective. This paper highlights some of the e-learning implementation efforts at the Addis Ababa Institute of Technology (AAiT) in Ethiopia. This case study shows that limited resources do not deter a developing nation to exploit the power of e-learning. Based on feedback from participants in the first national videoconferencing program held in Ethiopian higher education system between October 2011 and June 2012, the paper addresses the lessons learned and recommended actions for moving forward to a successful implementation of e-learning in Ethiopia, particularly in a videoconferencing mode.

Abstract Background As the healthcare system faced an acute shortage of personal protective equipment (PPE) during the COVID-19 pandemic, the use of 3D printing technologies became an innovative method of increasing production capacity to meet this acute need. Due to the emergence of a large number of 3D printed face shield designs and community-led PPE printing initiatives, this case study examines the methods and design best optimized for community printers who may not have the resources or experience to conduct such a thorough analysis. Case presentation We present the optimization of the production of 3D printed face shields by community 3D printers, as part of an initiative aimed at producing PPE for healthcare workers. The face shield frames were manufactured using the 3DVerkstan design and were coupled with an acetate sheet to assemble a complete face shield. Rigorous quality assurance and decontamination protocols ensured community-printed PPE was satisfactory for healthcare use. Conclusion Additive manufacturing is a promising method of producing adequate face shields for frontline health workers because of its versatility and quick up-start time. The optimization of stacking and sanitization protocols allowed 3D printing to feasibly supplement formal public health responses in the face of a global pandemic.

With the increasing economic accessibility of 3D printers, the lessons learned and the logics cultivated on digital Web 2.0 now seem applicable to the world of material things. Released in early 2012 by the artist groups F.A.T. and Sy-lab, the Free Universal Construction Kit is a set of 3D drawings that enable everyone with access to a 3D printer to make connectors between intellectual property restricted toys like LEGO, Tinkertoys, and Fischertechnik. However, when describing this project as “reverse engineering as a civic activity”, it becomes obvious that the Kit’s greater agenda is not just to enable cross-over playing, but rather, to problematize and perhaps ultimately open up closed formats through critical appropriation. But how does that, for instance, conform with the fact that the connectors are parasitically attached to these toys, whose logic it is simultaneously defying? And which (implicit) notions of creativity and play are at stake in this project, and to what extent do they fit the more general philosophical underpinnings of this project?

This article explores the practice of 3D printers from a playful perspective. Using the Ultimaker Original as a case study, it addresses the question of whether the practice of open source software and hardware in 3D printing is inherently playful and how the user affects and is affected by its playability. After examining the materiality of open source development and hacking processes in the Ultimaker Original, I will argue how playfulness of 3D printing stimulates hacking the 3D printer. From a broader perspective, the playful practice of 3D printing can be seen as part of a general development towards the ludification of culture.

This paper consists of an overview of programmes supporting sustainable planning and management in the City of Johannesburg one of the most important social and economic hubs of the transitional Republic of South Africa. Following from this is an analysis of the experience identified as most appropriate for Johannesburg City and its metropolitan region (Gauteng). This case study is used to highlight efforts and lessons learned from the international project "Designing, Implementing and Measuring Sustainable Urban Development" (DIMSUD) which have intended to contribute to new solutions for sustainable urban development through a collaborative multi-disciplinary, and participatory approach combining research, urban design, and capacity building. DIMSUD (http://sustainability.ethz.ch) is carried out jointly by the Swiss Federal Institute of Technology (ETH) Massachusetts Institute of Technology (MIT), Chalmers University of Technology (Sweden), University of Botswana, University of the Witwatersrand (South Africa) and the Catholic University of Santiago de Chile. Another partner was the United Nations University (UNU) at Tokyo. The project has enabled a global overview of core problems, providing a synthesis of realizable strategies and offering both a scientific forum and an "urban field laboratory" for joint learning. The strategies developed will not only help improve the conditions in the case study cities (Gaborone Johannesburg, Santiago de Chile), but will also provide working examples so that other cities can learn from and adapt and adopt appropriate "best practices".

The Numbas e-assessment system was first introduced to Cork Institute of Technology (CIT) in 2014. It has been implemented in several modules and is used regularly by a number of Lecturers. The aim of this case study was to investigate how embedded Numbas is in the Mathematics department in CIT and to examine the perceptions of the lecturing staff which have led to their individual adoptions of the Numbas e-assessment tool. The results of a survey of lecturers within the department show that the use of Numbas is common and varied and that Lecturers’ attitudes towards Numbas are positive. Several themes arose around ways to increase or improve the use of Numbas including the need for ongoing training and ideas for the broadening of use. Lessons learned could be applied to advancing the integration of Numbas in Cork Institute of Technology but may also be of use to others hoping to increase adoption of e-assessment in Mathematics within their institutions.

BACKGROUND Applications (apps) for smartphones and tablets are part of our daily life. Such apps give new opportunities for the health sector to improve the well-being of individuals and to support research. Good application development practices are essential for the success of an application. OBJECTIVE The objective of this study was to assess the current state of software engineering expertise in an academic sport science setting and to identify recommendations for successful project implementation. METHODS We conducted a questionnaire study to get insights in the actual development process for apps in a typical academic setting. The participants were (33 (SD=7) years, 58% were female) were recruited within the sport science faculty at the Karlsruhe Institute of Technology. The major topics of the survey developed by a multidisciplinary team were demographics, project information, development process, requirements and features, security, technology, and dissemination. RESULTS The questionnaire gave us a good overview on the heterogeneity of development projects and potential shortcomings. These shortcomings exist along the complete development lifecycle (e.g. development methodology, requirements engineering). CONCLUSIONS Based on these findings, we have proposed recommendations to improve the success probability and the sustainability of app development in a research context and give orientation on the potential roles that sport scientists should take.

The paper presents the possibility of using an innovative hydroxyapatite filament Ca10(PO4)6(OH)2 for printing in 3D printers of bone implants and the possibility of using it during implantation with voice prostheses. The introduction of an additional colloidal silver composite in voice implants will contribute to the reduction of bacterial infections, fungal infections and granulomatous hyperplasia. The creation of a stable external ring of the vocal fistula will remove complications associated with it with enlargement of the fistula and leakiness of voice implants. The ability to print with a hydroxyapatite filament will allow digital pre-surgery modeling of bone implants suited to the needs of surgical procedures.
