Measuring The Impact Of 3d Printers On The Health Of Youth, Alexis Kostin, Olla Obeid, Oz Trost
Measuring The Impact Of 3d Printers On The Health Of Youth, Alexis Kostin, Olla Obeid, Oz Trost
Wetterhahn Science Symposium Posters
3D printers are used more widely than ever before; they can be found in factories, hospitals, and even schools. However, the health effects of the VOCs and UFPs that these machines emit have yet to be fully understood. In collaboration with the University of Nevada, Las Vegas, this study utilizes an Air Gradient One sensor at the Diamond Lab to monitor VOC and UFP emissions before, during, and after 3D printing sessions. By comparing these levels to EPA and CDC safety standards, we aim to quantify the respiratory risks posed to youth.
Integrated Compliant Structure For A Hand Exoskeleton, Tristan R. Koopman
Integrated Compliant Structure For A Hand Exoskeleton, Tristan R. Koopman
Honors Undergraduate Theses
This thesis presents the design and prototyping of a wearable hand exoskeleton that integrates a flexible structural framework to assist with hand movement while maintaining comfort and anatomical conformity. The goal was to create a device that supports tendon-driven actuation through a compliant structure, combining elements of rigidity and flexibility to match the natural geometry and motion of the human hand. Traditional hand exoskeletons often trade off motion for structure or vice versa. This project aims to bridge that gap with a hybrid compliant design that balances flexibility and support. The design process followed an iterative approach involving rapid prototyping …

Additive Manufacturing For Medical Education, Michael Noon
Additive Manufacturing For Medical Education, Michael Noon
College of Engineering Summer Undergraduate Research Program
A growing body of evidence is suggesting that anatomical knowledge, the keystone of many medical specialties, is suffering among new graduates. While a host of reasons are provided, one common thread that many point to is the decline of cadaver dissections in the classroom. Many virtual audio-visual tools are used to address this gap, yet evidence has shown their ineffectiveness. Given this gap, the high degree of flexibility found in additive manufacturing (AM), and the many uses AM has already found in the medical field, we propose its use to fill this gap, allowing for students to learn with touch …

Modeling, Control, And Hardware Development Of A Thrust-Vector Coaxial Uav, Andrew North
Doctoral Dissertations and Master's Theses
This thesis introduces a unique thrust vector coaxial unmanned aerial vehicle (UAV) configuration and presents a comprehensive investigation encompassing dynamics modeling, hardware design, and controller development. Using the Newton-Euler method, a dynamic model for the UAV is derived to gain in-depth insights into its fundamental flight characteristics. A simple thrust model is formulated and modified by comparing it with data obtained from vehicle testing. The feasibility of manufacturing such a vehicle is assessed through the development of a hardware prototype. Finally, a linear state feedback controller is designed and evaluated using the non-linear dynamics model. The results demonstrate successful validation …

Additive Manufacturing (AM), also known as 3D Printing (3DP), is one of the newest manufacturing technologies with growing utilization in our daily life. Parallel to this growth, new materials, machines, and specific processes are being developed to produce parts in better-finished quality, at lower cost, and with shorter production time. However, workforce education in this evolving field has not advanced at the same pace as the technology, lacking proven curriculums, high-quality/accredited degree programs, and specialized advanced degrees. In this paper, some best practices established by the authors are introduced. The list is far from exhaustive but is proven to be …
Design And Fabrication Of A Polymer Fdm Printer Capable Of Build Parameter Monitoring And In-Sit Geometric Monitoring Via Photogrammetry, Travis Roberts
Design And Fabrication Of A Polymer Fdm Printer Capable Of Build Parameter Monitoring And In-Sit Geometric Monitoring Via Photogrammetry, Travis Roberts
All Theses
Additive manufacturing, or 3D printing, is a complex process that creates free-form geometric objects by sequentially placing material in a location to construct an object, usually as a layer-by-layer process. One of the most widespread methods is Fused Deposition Modeling (FDM). FDM is used in many of the consumer-grade polymer 3D printers available today. While consumer grade machines are cheap and plentiful, they lack many of the features desired in a machine used for research purposes and are often closed-source platforms. Commercial-grade models are more expensive and are also usually closed-source platforms that do not offer flexibility for modifications often …
Design For Additive Manufacturing (3d Printing), Michael O'Donnell, Michael J. Levy
Design For Additive Manufacturing (3d Printing), Michael O'Donnell, Michael J. Levy
Williams Honors College, Honors Research Projects
The goal of this project is to study the performance of a 3D printed mechanical part subjected to topology optimization. A part that is somewhat complex in its load bearing and geometry will be selected. That part will then be designed, finite element analysis will be performed on it to optimize its topology, and then it will be 3D printed and tested. The goal of topology optimization is to either save material cost and/or part weight due to the ability of 3D printing to manufacture parts with complex and obscure geometry.

Pressure mapping will give the weight distribution on an individual's food and the laser scanner will give the x-y coordinates of the foot. these two together will be used to generate a a 3D model which will then be 3D printed to create a custom orthotic. Research and material testing will also be done to determine the best material type to be used in …
Selective Resistive Sintering: A Novel Additive Manufacturing Process, Austin Bryan Van Horn
Selective Resistive Sintering: A Novel Additive Manufacturing Process, Austin Bryan Van Horn
Graduate Theses and Dissertations
Selective laser sintering (SLS) is one of the most popular 3D printing methods that uses a laser to pattern energy and selectively sinter powder particles to build 3D geometries. However, this printing method is plagued by slow printing speeds, high power consumption, difficulty to scale, and high overhead expense. In this research, a new 3D printing method is proposed to overcome these limitations of SLS. Instead of using a laser to pattern energy, this new method, termed selective resistive sintering (SRS), uses an array of microheaters to pattern heat for selectively sintering materials. Using microheaters offers significant power savings, significantly …
The Risks Of Revolution: Ethical Dilemmas In 3d Printing From A Us Perspective, Erica L. Neely
The Risks Of Revolution: Ethical Dilemmas In 3d Printing From A Us Perspective, Erica L. Neely
Philosophy and Religion Faculty Scholarship
Additive manufacturing has spread widely over the past decade, especially with the availability of home 3D printers. In the future, many items may be manufactured at home, which raises two ethical issues. First, there are questions of safety. Our current safety regulations depend on centralized manufacturing assumptions they will be difficult to enforce on this new model of manufacturing. Using current US law as an example, I argue that consumers are not capable of fully assessing all relevant risks and thus continue to require protection any regulation will likely apply to plans, however, not physical objects. Second, there are intellectual …
