Purpose In this era of Fourth Industrial Revolution, also known as Industry 4.0, additive manufacturing (AM) has been recognized as one of the nine technologies of Industry 4.0 that will revolutionize different sectors (such as manufacturing and industrial production). Therefore, this study aims to focus on “Additive Manufacturing Education” and the primary aim of this study is to investigate the impacts of AM technology at selected South African universities and develop a proposed framework for effective AM education using South African universities as the case study. Design/methodology/approach Quantitative research approach was used in this study, that is, a survey (questionnaire) was designed specifically to investigate the impacts of the existing AM technology/education and the facilities at the selected South African universities. The survey was distributed to several students (undergraduate and postgraduate) and the academic staffs within the selected universities. The questionnaire contained structured questions based on five factors/variables and followed by two open-ended questions. The data were collected and analyzed using statistical tools and were interpreted accordingly (i.e. both the closed and open-ended questions). The hypotheses were stated, tested and accepted. In conclusion, the framework for AM education at the universities was developed. Findings Based on different literature reviewed on “framework for AM technology and education”, there is no specific framework that centers on AM education and this makes it difficult to find an existing framework for AM education to serve as a landscape to determine the new framework for AM education at the universities. Therefore, the results from this study made a significant contribution to the body of knowledge in AM, most especially in the area of education. The significant positive responses from the respondents have shown that the existing AM in-house facilities at the selected South African universities is promoting AM education and research activities. This study also shows that a number of students at the South African universities have access to AM/3D printing lab for design and research purposes. Furthermore, the findings show that the inclusion of AM education in the curriculum of both the science and engineering education is South Africa will bring very positive results. The introduction of a postgraduate degree in AM such as MSc or MEng in AM will greatly benefit the South African universities and different industries because it will increase the number of AM experts and professionals. Through literature review, this study was able to identify five factors (which includes sub-factors) that are suitable for the development of a framework for AM education, and this framework is expected to serve as base-line or building block for other universities globally to build/develop their AM journey. Research limitations/implications The survey was distributed to 200 participants and 130 completed questionnaires were returned. The target audience for the survey was mainly university students (both undergraduate and postgraduate) and the academics who have access to AM machines or have used the AM/3D printing lab/facilities on their campuses for both academic and research purposes. Therefore, one of the limitations of the survey is the limited sample size; however, the sample size for this survey is considered suitable for this type of research and would allow generalization of the findings. Nevertheless, future research on this study should use larger sample size for purpose of results generalization. In addition, this study is limited to quantitative research methodology; future study should include qualitative research method. Irrespective of any existing or developed framework, there is always a need to further improve the existing framework, and therefore, the proposed framework for AM education in this study contained only five factors/variables and future should include some other factors (AM commercialization, AM continuous Improvement, etc.) to further enhance the framework. Practical implications This study provides the readers and researchers within the STEM education, industry or engineering education/educators to see the importance of the inclusion of AM in the university curriculum for both undergraduate and postgraduate degrees. More so, this study serves as a roadmap for AM initiative at the universities and provides necessary factors to be considered when the universities are considering or embarking on AM education/research journey at their universities. It also serves as a guideline or platform for various investors or individual organization to see the need to invest in AM education. Originality/value The contribution of this study towards the existing body of knowledge in AM technology, specifically “AM education research” is in the form of proposed framework for AM education at the universities which would allow the government sectors/industry/department/bodies and key players in AM in South Africa and globally to see the need to invest significantly towards the advancement of AM technology, education and research activities at various universities.

Purpose This paper aims to provide a comprehensive overview of the recent applications of additive manufacturing (AM) research and activities within selected universities in the Republic of South Africa (SA). Design/methodology/approach The paper is a general review of AM education, research and development effort within selected South African universities. The paper begins by looking at several support programmes and investments in AM technologies by the South African Department of Science and Technology (DST). The paper presents South Africa’s AM journey to date and recent global development in AM education. Next, the paper reviews the recent research activities on AM at four selected South African universities, South Africa AM roadmap and South African AM strategy. The future prospects of AM education and research are then evaluated through a SWOT analysis. Finally, the paper looks at the sustainability of AM from an education perspective. Findings The main lessons that have been learnt from South African AM research activities within selected universities are as follows: AM research activities at South African universities serve as a platform to promote AM education, and several support programmes and investments from South Africa’s DST have greatly enhanced the growth of AM across different sectors, such as medical, manufacturing, industrial design, tooling, jewellery and education. The government support has also assisted in the actualisation of the “Aeroswift” project, the world’s largest and fastest state-of-the-art AM machine that can 3D print metal parts. The AM research activities within South Africa’s universities have shown that it is not too late for developing countries to start and embrace AM technologies both in academia and industry. Based on a SWOT analysis, the future prospects of AM technology in SA are bright. Practical implications Researchers/readers from different backgrounds such as academic, industrial and governmental will be able to learn important lessons from SA’s AM journey and the success of SA’s AM researchers/practitioners. This paper will allow the major investors in AM technologies and business to see great opportunities to invest in AM education and research at all educational levels (i.e. high schools, colleges and universities) in South Africa. Originality/value The authors believe that the progress of AM education and research activities within SA’s universities show good practice and achievement over the years in both the applications of AM and the South African AM strategy introduced to promote AM research and the educational aspect of the technologies.

Purpose This study aims to examine six South African universities with a particular focus on the quality of teaching and learning. Design/methodology/approach A qualitative case study approach was adopted and data were mainly generated by means of open-ended questionnaires. The questionnaire was circulated to approximately 1,800 students and 746 completed it. The data were categorized and analysed thematically, using both national and international benchmarks for quality teaching and learning. Findings The findings reveal that teaching and learning in South African universities is marred by a plethora of challenges. Lecturers lack basic skills and essential resources to effectively facilitate teaching and learning. Furthermore, quality benchmarks set by the Council on Higher Education are only met on paper and little or nothing is done to translate this into practice. Originality/value The study proposes among others that clearer policies on funding are recommended to ensure proper allocation of resources, staff development and institutional comeliness. Finally, to enhance transformation, universities should prioritize teaching and learning and take steps to ensure that those teaching in the classroom are qualified to do so.

PurposeInnovative startups have begun a trend using laser sintering (LS) technology patents expiration, namely, by introducing LS additive manufacturing (AM) machines that can overcome utilization barriers, such as the costliness of machines and productivity limitation. The recent rise of this trend has led the authors to investigate this new class of machines in novel settings, including hub configuration. There are various supply chain configurations to supply spare parts in industrial operations. This paper aims to explore the promise of a production configuration that combines the benefits of centralized production with the flexibility of local manufacturing without the huge costs related to it.Design/methodology/approachThis study quantitatively examines the feasibility of different AM-enabled spare parts supply chain configurations. Using cost data extracted from a case study, three scenarios per AM machine technology are modeled and compared.FindingsResults suggest that hub production configuration depending on the utilized AM machines can provide economic efficiency and effectiveness to reduce equipment downtime. While previous studies have suggested the need for AM machines with efficiency for single part production for a distributed supply chain, the findings in this research illustrate the positive relationship between multi-part production capability and the feasibility of a hub manufacturing configuration establishment.Originality/valueThis study explores the promise of a production configuration that combines the benefits of centralized production with the flexibility of local manufacturing without the huge costs related to it. Although the existing body of knowledge contains research on production decentralization, research on various levels of decentralization is lacking. Using a real-world case study, this study aims to compare the feasibility of different levels of decentralization for AM-enabled spare parts supply chains.

Purpose This paper aims to explore the development narrative and usage of environmental sustainability tours available at universities and takes an in-depth look into the Western Kentucky University (WKU) Green Tour. Design/methodology/approach Questionnaires and interviews were conducted with sustainability leaders involved in tours at their university to discover how they were developed and used. An assessment of the WKU Green Tour used surveys and pre- and post-tests to determine the reach of the tour to the campus population, student learning and faculty use. Findings There is a lack of data on sustainability tours, making it difficult to design new tours and validate their status as an essential tool. In the case of WKU, the need for data was confirmed, as current practices that were assumed to be effective proved ineffective. Multiple suggestions for improved tours are provided. Research limitations/implications The case study used in this paper is not representative of all university sustainability tours as they can vary widely. Given the lack of research on the subject, especially quantitative research, it is a valuable study. Practical implications Though sustainability tours are touted as a valuable tool for all campuses, more data are needed to validate this claim. Data suggest the tours are effective tools for increasing knowledge, but there is need for further assessment of tours and how they can be used to create a sustainably literate campus. Originality/value This study is the first to assess sustainability tours using mixed-methods.

Purpose The purpose of this paper is to explore the composition of “tourism experience” of tourist visiting during the Nabakalebara event at Puri, India. Design/methodology/approach The paper applies data reduction using exploratory factor analysis on a sample of 300 respondents drawn during the event and condenses a set of 20 attributes into a list of five compressible factors. Findings The research shows that visitors visualise tourism experience as a combination of five factors: education, entertainment, esthetics, escapism and ease of facilities. They assigned different weightage in terms of significance to each of these factors. Internal configuration of these factors also reveals interesting patterns. Research limitations/implications A non-probability sampling method is applied in this research. Future studies should replicate the research in different social, economic and geographical context to see if the factor composition and structure remain unchanged. Practical implications Organisers should focus on improving ease of facilities. Disproportionate expenditure on adding to other factors is not expected to yield matching dividends. Social implications The study assumes significance as this kind of event used to happen on every 15 years. This attracts millions of visitors. The paper explores the expectation of visitors. Originality/value This paper is among the few works done on understanding tourism experience during the Nabakalebara at Puri, India. It adds significantly to the meagre body of knowledge in the area of tourism experience.

Graduate Unemployment

PurposeThe purpose of this paper is to explore youth graduate unemployment and unemployability as a development problem in South Africa.Design/methodology/approachThis exploratory study applied a qualitative research method to elicit the perspectives of youth graduates regarding their unemployment and unemployability. A total of 30 face-to-face semi-structured interviews were conducted with unemployed youth who recently graduated from five South African universities.FindingsThe results indicate that, as youth graduate unemployment increases in South Africa, graduates become hopeless in terms of securing employment. The participants attributed their unemployment to multidimensional factors that include limited demand in the labour market, skills mismatch and lack of work experience.Research limitations/implicationsThis research exclusively focused on graduates from five South African universities; hence, the results of this small qualitative study cannot be generalised to the entire South African population. However, this paper offers important insights that may form the foundation for a nationwide study on a related topic.Originality/valueThis paper presents important insights that influence policy makers, government and other relevant stakeholders to develop alternative solutions to youth graduate unemployment. This paper recommends that government should play a critical role in bridging the gap between higher education and industry in order to address youth graduate unemployment. It also calls for a more cooperative effort between government, higher learning institutions and employers in order to create job opportunities for youth graduates in South Africa.

Purpose Fabrication of customized products in low volume through conventional manufacturing incurs a high cost, longer processing time and huge material waste. Hence, the concept of additive manufacturing (AM) comes into existence and fused deposition modelling (FDM), is at the forefront of researches related to polymer-based additive manufacturing. The purpose of this paper is to summarize the research works carried on the applications of FDM. Design/methodology/approach In the present paper, an extensive review has been performed related to major application areas (such as a sensor, shielding, scaffolding, drug delivery devices, microfluidic devices, rapid tooling, four-dimensional printing, automotive and aerospace, prosthetics and orthosis, fashion and architecture) where FDM has been tested. Finally, a roadmap for future research work in the FDM application has been discussed. As an example for future research scope, a case study on the usage of FDM printed ABS-carbon black composite for solvent sensing is demonstrated. Findings The printability of composite filament through FDM enhanced its application range. Sensors developed using FDM incurs a low cost and produces a result comparable to those conventional techniques. EMI shielding manufactured by FDM is light and non-oxidative. Biodegradable and biocompatible scaffolds of complex shapes are possible to manufacture by FDM. Further, FDM enables the fabrication of on-demand and customized prosthetics and orthosis. Tooling time and cost involved in the manufacturing of low volume customized products are reduced by FDM based rapid tooling technique. Results of the solvent sensing case study indicate that three-dimensional printed conductive polymer composites can sense different solvents. The sensors with a lower thickness (0.6 mm) exhibit better sensitivity. Originality/value This paper outlines the capabilities of FDM and provides information to the user about the different applications possible with FDM.
