Abstract
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.

Abstract
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.

Abstract
Purpose
The development and introduction of novel hypoallergenic foods represents a potential approach to reducing the negative health impacts of food allergy. The purpose of this paper is to assess whether novel hypoallergenic foods will be accepted by food chain actors and consumers.
Design/methodology/approach
Stakeholder opinions (collated using semi‐structured interviews (n=16)) regarding the acceptability of novel hypoallergenic foods were assessed. Three focus groups were applied to understand the opinions of food allergic consumers.
Findings
Food allergic consumers expressed a preference for a “cure” for food allergy. However, they acknowledged that hypoallergenic foods had the potential to improve the quality of lives of food allergy sufferers through increasing dietary variation and reducing restrictions on product selection. Stakeholders supported the introduction of novel foods (although this support was not universal), assuming that the products were acceptable to food allergic consumers, consumers in general and regulators.
Originality/value
The paper is likely to be useful for the potential developers of hypoallergenic foods, allergen food products (food industry and scientists) and policy makers regarding the commercialisation of novel hypoallergenic foods and their regulation.

Abstract
Purpose
The purpose of this paper is to explore the detection and prevention of elder financial abuse through the lens of a “professional bystander intervention model”. The authors were interested in the decision cues that raise suspicions of financial abuse, how such abuse comes to the attention of professionals who do not have a statutory responsibility for safeguarding older adults, and the barriers to intervention.
Design/methodology/approach
In‐depth interviews were conducted using the critical incident technique. Thematic analysis was carried out on transcribed interviews. In total, 20 banking and 20 health professionals were recruited. Participants were asked to discuss real cases which they had dealt with personally.
Findings
The cases described indicated that a variety of cues were used in coming to a decision that financial abuse was very likely taking place. Common to these cases was a discrepancy between what is normal and expected and what is abnormal or unexpected. There was a marked difference in the type of abuse noticed by banking and health professionals, drawing attention to the ways in which context influences the likelihood that financial abuse will be detected. The study revealed that even if professionals suspect abuse, there are barriers which prevent them acting.
Originality/value
The originality of this study lies in its use of the bystander intervention model to study the decision‐making processes of professionals who are not explicitly charged with adult safeguarding. The study was also unique because real cases were under consideration. Hence, what the professionals actually do, rather than what they might do, was under investigation.
