...From cliché to inception: a review of Bioprinting Tyler Crossley MCB 404 Biomedical Ethics Dr. Pimentel Introduction The utilization of 3-dimmensional printers to produce functional applications by the personal and consumer sectors have been acknowledged since the development of this technology. Two categories for product applications of 3-dimmensional printing exist: products to improve individual personal life, such as hearing aids and prosthetic limbs; engineering parts for many consumer products, such as many components of engines, guns and even musical instruments. Whichever contextual application of this technology is desired and utilized, both ethical benefits and weaknesses exist. Multiple American companies including General Electric, Boeing, Nike, Honeywell and others have used this technology in manufacturing motor components, shoes, solar panels and other consumer products. Endless potential applications of 3-dimmensional printing exist for future developments. Interestingly, printing of meat for human consumption as an alternative to harvesting meat from animals is currently being researched. In 2008 PeTA offered a $1 million X-Prize style reward for the first group to synthetically develop such commercially viable meat. This is one case in which proposing ethical dilemmas exist, and the many alternative controversies this topic entails. Further bioethical dilemma’s and considerations exist and will be discussed...

...economics research arm of McKinsey & Company, was established in 1990 to develop a deeper understanding of the evolving global economy. Our goal is to provide leaders in the commercial, public, and social sectors with the facts and insights on which to base management and policy decisions. MGI research combines the disciplines of economics and management, employing the analytical tools of economics with the insights of business leaders. Our “micro-to-macro” methodology examines microeconomic industry trends to better understand the broad macroeconomic forces affecting business strategy and public policy. MGI’s in-depth reports have covered more than 20 countries and 30 industries. Current research focuses on four themes: productivity and growth, the evolution of global financial markets, the economic impact of technology and innovation, and urbanization. Recent reports have assessed job creation, resource productivity, cities of the future, and the impact of the Internet. MGI is led by McKinsey & Company directors Richard Dobbs and James Manyika. Yougang Chen, Michael Chui, Susan Lund, and Jaana Remes serve as MGI principals. Project teams are led by a group of senior fellows and include consultants from McKinsey’s offices around the world. These teams draw on McKinsey’s global network of partners and industry and management experts. In addition, leading economists, including Nobel laureates, act as research advisers. The partners of McKinsey & Company fund MGI’s research; it is...

...Front. Mech. Eng. 2013, 8(3): 215–243 DOI 10.1007/s11465-013-0248-8 REVIEW ARTICLE Nannan GUO, Ming C. LEU Additive manufacturing: technology, applications and research needs © Higher Education Press and Springer-Verlag Berlin Heidelberg 2013 Abstract Additive manufacturing (AM) technology has been researched and developed for more than 20 years. Rather than removing materials, AM processes make three-dimensional parts directly from CAD models by adding materials layer by layer, offering the beneficial ability to build parts with geometric and material complexities that could not be produced by subtractive manufacturing processes. Through intensive research over the past two decades, significant progress has been made in the development and commercialization of new and innovative AM processes, as well as numerous practical applications in aerospace, automotive, biomedical, energy and other fields. This paper reviews the main processes, materials and applications of the current AM technology and presents future research needs for this technology. Keywords additive manufacturing (AM), AM processes, AM materials, AM applications 1 Introduction The ASTM F42 Technical Committee defines additive manufacturing (AM) as the “process of joining materials to make objects from three-dimensional (3D) model data, usually layer upon layer, as opposed to subtractive manufacturing methodologies” [1]. It is also known as additive fabrication, additive processes, direct digital...
