3D printing is a process of making three-dimensional objects using additive processes where layers are laid down in succession to create a complete object. Companies across the globe are actively piloting and leveraging the inherent benefits of 3D printing technology. Today, 3D printing can revolutionize food innovation and production through better creativity, customizability, and sustainability. This article highlights 3D printing evolving technologies and trends and identifies its applications and implementation challenges. In this paper, we conducted a literature review to explore 3D printing's current technologies and applications in the food industry, including its advantages, its potential implications, and its obstacles to rapid growth. Finally, the article investigates the future of 3D printing in the food industry. Our discussions bring new insight into the application transformative potentials of 3D food printing of 3D printing techniques and provide practitioners decision-makers a way to discover more effective strategies to adopt 3D food printing technology.

The use of Digital Twin technology has been expanding rapidly, and projections indicate that it will continue to proliferate across various applications, use cases, and industries, including healthcare. In recent years, the healthcare sector has seen an acceleration in digital transformation. This fast-paced change offers both opportunities and risks, especially with emerging technologies like digital twins, which are relatively untested and still in the early stages of adoption in medical care. This paper aims to conduct a literature review to explore how digital twins facilitate intelligent automation in healthcare. It defines the concept, traces the technology’s evolution and development, reviews its key enabling technologies, and examines current trends and challenges. The paper also presents a range of application examples in personalized medicine and public health, concluding with a succinct discussion of the primary technical and ancillary challenges, as well as the ethical issues that arise when applying digital twin technology to human subjects.

A circular economy approach within wastewater consumption for agriculture has gained relevance in recent years. Extreme climate conditions (e.g., megadrought in California) have resulted in severe water shortages, yet there seems to be a reluctance to accept alternative water sources. Despite the numerous local initiatives towards oilfield water reuse, barriers remain to its implementation in practice. This study identifies the barriers towards widespread adoption of Oilfield Produced Water (OPW) for crop irrigation. Semi-structured interviews were conducted with five major stakeholder groups of the OPW: oil and gas managers/ business owners, farmers, entrepreneurs, water district managers, and water board personnel. This study used qualitative data analysis to identify factors influencing the beneficial uses and barriers to reusing OPW. The findings highlighted three macro-categories: water shortages, costs of treatment Vs. the expected benefits, and public perceptions vs. scientific studies based on thematic relevance and coherence. The interviews revealed the need for a tighter collaboration among the various stakeholder groups in this ecosystem that involves public-private partnerships and shared governance in managing the environment—addressing these barriers aids the development of a circular economy for wastewater.
