Additive Manufacturing: A Summary of the Literature

The Center for Economic Development at the Levin College of Urban Affairs at Cleveland State University prepared this report for the Ohio Manufacturing Institute (OMI) at The Ohio State University. The objective of this study is to provide background analysis of additive manufacturing (AM) for the OMI as they prepare a roadmap for the future and recommendations on AM for the Ohio Development Services Agency (ODSA).1 This report is a literature review and summary of findings. Literature on AM was collected from various sources. Academic articles, reports, and studies were collated and analyzed from databases, internet searches, and publications. The goal of this report is to provide a clear context of the state, national, and international conversation on AM, as well as delineate opportunities and challenges as it relates to this technology. It is important to note two major considerations in this literature review: the designation between AM and 3D printing, and overall technical specifications: (1) AM is known in the mainstream media as “3D printing,” but in actuality, this designation is a subset of the AM concept. On occasion, this report will single out 3D printing technology as a subset of AM. There is a vast amount of material on 3D printing because it is currently a popular subject for the media. At times, the literature refers to 3D printing separately from AM, and it is unknown to the authors of this report whether these different designations are deliberate. To avoid confusion, we use both concepts and report the labeling as the literature refers to it. This provides clarity for the reader. (2) There is a significant amount of technical information in the AM literature that is not covered in this report. This report is designed only to consider AM in the context of the overall conversation. No technical information, mathematics, or other technical concepts involved in the AM conversation will be covered

Consuming Digital Debris in the Plasticene

Claims of customization and control by socio-technical industries are altering the role of consumer and producer. These narratives are often misleading attempts to engage consumers with new forms of technology. By addressing capitalist intent, material, and the reproduction limits of 3-D printed objects’, I observe the aspirational promise of becoming a producer of my own belongings through new networks of production. I am interested in gaining a better understanding of the data consumed that perpetuates hyper-consumptive tendencies for new technological apparatuses. My role as a designer focuses on the resolution of not only the surface of the object through 3-D printing, but the social implications to acknowledge consequential conditions of new forms of consumer technology

Exploring the Utilization of Augmented Reality in Higher Education Perceptions of Media and Communication Students

The present study aims to explore the perceptions and usage of Augmented Reality (AR) technology among media students in Palestinian universities. A quantitative approach was adopted, and data was gathered from a web-based survey of 237 media students. The Technology Acceptance Model (TAM) was utilized to gauge participants' perceptions of AR, and descriptive statistics were used for analysis. The findings reveal a generally positive perception of AR as a beneficial tool for skill enhancement, with mean scores ranging from 3.70 to 4.04 indicating strong agreement. The study also found moderate to high AR usage among participants, particularly for translating texts using Google Translate, but noted that usage patterns were more individual-oriented. Additionally, 91.1% of respondents attributed the COVID-19 pandemic to increased technology usage in higher education. The novelty of this study lies in providing insights into the perception and application of AR in higher education within the Palestinian context, an under-researched area. The study sheds light on the potential for integrating AR more formally into curricula, which could foster a more engaging and immersive educational experience. However, it also highlights the need to address barriers such as lack of technical support and possible discomfort with technology. Doi: 10.28991/ESJ-2023-SIED2-016 Full Text: PD

THE ROLE OF COMPUTER AIDED ENGINEERING IN DEVELOPING A COMBINED TRASH AND RECYCLING TRUCK : A CASE STUDY

This work will illustrate how Environmental America Inc., EAI, and the Clemson University design team utilized lean manufacturing principles to revolutionize the curbside waste collection process. Through the application of lean manufacturing principles the number of non-value added steps was significantly reduced and the information gathered from the lean process tree acted as a framework to develop initial constraints and criteria for the vehicle\u27s development. The design team was asked to construct the fifth iteration of the prototype collection vehicle in an effort to minimize vehicle cost, size and weight. An extensive case study will be presented which illustrates how the design team utilized CAE to optimize the proposed prototype baling system. The investigation is conducted through the use of an \u27observer as participant\u27 form of case study. The EAI combined collection vehicle was selected as the focus of the study due to the complexity and size of the system, as it has a significantly larger scope than those presented in classic academic engineering design projects. Since previous prototypes have been developed without the use of CAE software or additional engineering tool support, a benchmark for comparison exists which will directly demonstrate the benefits and limitations of the chosen software. Currently, CAE and FEA software is often used for product validation, system optimization, and parametric studies, however, this paper will demonstrate how CAE and FEA can be utilized to verify physical experimentation. The results of this case study will show that although the use of CAE significantly reduces lead time and cost associated with product development, the software can be extremely hazardous when used inappropriately

The culture in fabrication: the 21st century makespace as a flexible, open source tool to inspire a maker community

Thesis is submitted in partial fulfilment for the degree of Master of Architecture to the Faculty of Engineering and the Built Environment, School of Architecture and Planning at the University of the Witwatersrand, Johannesburg, 2017The world is standing on the cusp of a third industrial revolution that will see an explosion of creativity, knowledge creation and innovation. South Africa is at the forefront of a different revolution, one that is concerned with the access to knowledge and education. While these revolutions are somewhat different, they fight for the same ideal; that is a world where information and education are available to all, such that people are inspired to innovate, create and empower themselves through the development and use of new knowledge. These revolutions will be facilitated by a number of factors, but what is architecture’s role? This research report discusses a makerspace as an architectural response to the coming knowledge revolution and what this typology means in the context of Johannesburg, South Africa. The author makes reference to the theoretical understanding of maker culture as the celebration of creativity and innovation and that a makerspace facilitates access to the tools and space required so that anyone can make. The intent of this research report is to create an architectural intervention based on extensive research of related theories, careful analysis of the context and various precedent studies. The key issue is determining how the typology affects and is affected by the context. The author utilises the context of Newtown, Johannesburg for the intervention due to its history as a primarily industrial area that grew into a cultural hub of the city. In a World where knowledge has become a privatised commodity, this research report explores how architecture, specifically in the form of a makerspace, can democratise access to information, empower the individual and the community, and boost a stagnant local economy through the encouragement of entrepreneurship.MT201
