The present study is a horizon scanning report based on the British model Sigma Scan. It explores possible future issues and trends in 3D printing and its potential impact on society, particularly with regard to new security threats that its spread is expected to cause. This exercise allows for an examination based on the best predictions of how the future of this disruptive and, at the same time, enabling technology is likely to be, in order to better understand the uncertainties that its development will bring. This report addresses the potential implications of the development of 3D printing, in particular for crimes, the likely early indicators of the development of this technology, the simultaneous developments that can serve as inhibitors and drivers, the potential crime preventers and promoters, and the evidence that indicates the possibility of the predicted events. Keywords: 3D printing, additive manufacturing, disruptive technology, enabling technology, security risks.

Metal 3D Printing

Purpose With the overarching idea of disruptive technology and its effects on business, this paper focuses on how companies strategically consider meeting the challenge of a disruptive technology such as additive manufacturing. The purpose of this paper is to describe and discuss changes in positions and roles related to the implementation of a disruptive technology. Design/methodology/approach Additive manufacturing could be expected to have different consequences for parties based on their current supply chain positions. The paper therefore investigates companies’ strategies related to various supply chain positions and does so by departing from a position and role point of view. Three business cases related to metal 3D printing - illustrating sub-suppliers, manufacturers and logistics firms - describe as many strategies. Data for the cases were collected through meetings, interviews, seminars and secondary data focusing on both current business activities related to additive manufacturing and scenarios for the future. Findings The companies attempted to defend their current positions, leading to new roles for them. This disconnects the change of roles from that of positions. The changed roles indicate that all parties, regardless of supply chain positions, would move into competing producing roles, thereby indicating how a disruptive technology may disrupt network structures based on companies’ attempts to defend their positions. Originality/value The paper contributes to previous research by reporting a disconnect between positions and roles among firms when disruption takes place. The paper further denotes how the investigated firms largely disregarded network consequences at the disruptive stage, caused by the introduction of additive manufacturing. The paper also contributes to research on additive manufacturing by including a business dimension and linking this to positions and roles.

Purpose The purpose of this paper is to discuss the current state-of-the-art in additive manufacturing, more commonly known as 3D printing, from the business perspectives. The primary drivers behind the development of the associated technologies are considered along with features that limit growth. Design/methodology/approach The approach is a personal perspective, based on approximately 25-years study of the development of the associated technologies and applications. Findings The discussion has found that the technology is still growing healthily, but with an understanding that there are numerous application areas that should be considered separately. Some areas are significantly more mature than others and success in some areas does not guarantee success in others. Originality/value This viewpoint has been prepared for the current state-of-the-art and can be compared with earlier viewpoints to see how things may have changed in the past. This should be of value to those interested to explore how the technology has developed in recent times and how it may move into the future.

The Future

This work presents the review of locomotives and the future of railway automotive power in Africa. Locomotives down time on account of inadequate spare parts still remains a challenge in African. It is thus, imperative to review the locomotives in African, to establish the current capabilities as well as provide recommendations to bridge the gaps and its extrapolated trends in future. Firstly, the comparison factors were track length, electrified rails, number of locomotives and yearly passengers on each of Egypt, Ghana, Kenya, Nigeria, South Africa and Zambia rails. Secondly, the focus was on engine parameters from literatures and maintenance logbooks of locomotives. From available data, it was found that South Africa and Egypt have more advanced rail system than the rest four selected countries. It was also found that additive manufacturing, 3D printing, ductile cast iron and die-forging can be used to produce the engine body for diesel engine using steel and aluminum alloys while aluminum silicon and tin doped with copper are good for reciprocation mechanisms. And finally, increased reliability of locomotives can be guided by an engine selection matrix, while use of renewable and energy hybridization are needed to meet the expansion of railroads in Africa.

The Future

Abstract Stories of using 3D printing to respond to the pandemic throw a spotlight on additive manufacturing and its potential for fast, flexible production of critically needed parts. Whether it was face shields, nasopharyngeal swabs, or respiratory masks, additive manufacturing rose to the challenge to fill in the gap caused by a disrupted supply chain. Now, some industry observers are starting to ask whether 3D printing could be the future of manufacturing.
