The COVID-19 pandemic has caused a surge of demand for medical supplies and spare parts, which has put pressure on the manufacturing sector. As a result, 3D printing communities and companies are currently operating to ease the breakdown in the medical supply chain. If no parts are available, 3D printing can potentially be used to produce time-critical parts on demand such as nasal swabs, face shields, respirators, and spares for ventilators. A structured search using online sources and feedback from key experts in the 3D printing area was applied to highlight critical issues and to suggest potential solutions. The prescribed outcomes were estimated in terms of cost and productivity at a small and large scale. This study analyzes the number and costs of parts that can be manufactured with a single machine within 24 h. It extrapolates this potential with the number of identical 3D printers in the world to estimate the global potential that can help practitioners, frontline workers, and those most vulnerable during the pandemic. It also proposes alternative 3D printing processes and materials that can be applicable. This new unregulated supply chain has also opened new questions concerning medical certification and Intellectual property rights (IPR). There is also a pressing need to develop new standards for 3D printing of medical parts for the current pandemic, and to ensure better national resilience.

Hackathons are time-bounded crowdsourcing events, which have recently prospered in many technology and science domains across the globe. We study Europe’s largest hackathon, Junction, to better understand the distinct crowdsourcing properties and mechanisms of this type of hackathon as a form of tournament-based crowdsourcing. Moreover, we determined how they add value to attending companies and participants. In this regard, six qualitative and quantitative datasets from participants, companies, and the organizer were collected and analyzed. Our findings revealed five distinct crowdsourcing properties and mechanisms of mega hackathons, including intricate crowd selection, strong crowd vibe, instant crowd feedback, versatile crowd potential, and pervasive information technology. Based on our findings, we argue that these properties and mechanisms increase the possibility of finding innovative solutions to companies’ problems in Junction-like mega hackathons. This article concludes with managerial implications for companies to consciously plan and prepare while knowing what to expect during the hackathon.

This paper aims to determine whether additive manufacturing (AM) always simplifies the supply chain. The advent of AM as a final-parts production method can radically impact supply chains. Due to AM's inherent characteristics that suit customised production and complex geometries, utilization of this technology continues to expand into various industries (e.g. aviation, defence, automobile, medicine). Some of the crucial areas that AM can contribute to are cost reduction and simplification of organizations' supply chains. An objective examination of the entire supply chain rather than merely focusing on production cost is important when studying the impact of switch-over from conventional to additive manufacturing. Supply chain complexity is caused by the proliferation of products, processes, suppliers, and markets, resulting in additional costs and decreased company profit. Therefore, to clearly illustrate the benefits and shortcomings of a switch-over to AM, it is necessary to investigate this transition in depth. In this paper, we analysed supply chain complexity before and after the implementation of AM in three case companies from distinct industries by conducting interviews or utilizing publicly available information. Our findings underline the simplification of supply chain in one of the cases, after the switch to AM, while it resulted in slightly higher complexity in another case. In the third case, the impact of switching to AM on the supply chain complexity is dependent on several variables. We contribute to the literature by elucidating on the common belief that AM simplifies the supply chain. We found that the implementation of AM is not a silver bullet to reduce the complexity of every supply chain.

In this paper, a use case related to smart buildings is presented to illustrate the application of IoT-enabled workplaces. The data collected from two office spaces are compared using efficient data analytics method. For this comparison, the environmental factors considered are temperature, humidity, air quality, and workplace particle numbers. This paper demonstrates how to build IoT-enabled workplaces and illustrates its actual benefits to energy management and remote systems monitoring and control. A survey was conducted by the Department of Industrial Engineering and Management at Aalto University, and responses were submitted from 50 unique users to illustrate the incentives regarding IoT-enabled workplaces and to study occupants' preferences. Moreover, the research results contribute to the facility management of companies and organizations by suggesting novel methods for providing more efficient and effective IoT-enabled workplaces.
