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 …

3-Axis Automated Probe Traverse For Aerodynamic Testing, Tananant Boonya-Ananta, Ricky Wai, Zander Oostman, Teyvon Brooks
Mechanical Engineering
Our primary objective is to design, build, and test an automated traverse to hold measurement probes in Cal Poly’s low speed wind tunnel. The device should cause minimal flow disturbance. It’s movements must be able to cover eighty percent of the three-dimensional test section. The device should have a mounting point for interchangeable probes. The assembly is to be integrated with the current frame structure on the wind tunnel test section, and should allow very minimal deflection of the measurement probe. The user should be able to control the motion of the traverse via a computer interface which supports automatic …

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 …

Modelling Of Coal-Biomass Blends Gasification And Power Plant Revamp Alternatives In Egypt’S Natural Gas Sector, Dalia A. Ali Eng, Mamdouh A. Gadalla Prof., Omar Y. Abdelaziz, Fatma H. Ashour Prof.
Chemical Engineering
Recently, there has been a growing research interest in the co-gasification of biomass with coal to produce syngas and electricity in a sustainable manner. Co-gasification technology do not only decrease potentially the exploitation of a significant amount of conventional coal resources, and thus lower greenhouse gases (GHG) emissions, but also boost the overall gasification process efficiency. In the present work, a rigorous simulation model of an entrained flow gasifier is developed using the Aspen Plus® software environment. The proposed simulation model is tested for an American coal and the model validation is performed in good agreement with practical data. The …
Design And Analysis Of The Impact Diffusion Helmet Through A Finite Element Analysis Approach, Steven Paul Warnert
Design And Analysis Of The Impact Diffusion Helmet Through A Finite Element Analysis Approach, Steven Paul Warnert
Master's Theses
By applying the finite element approach to the design and analysis of the impact diffusion helmet, many helmet configurations were able to be analyzed. Initially it was important to determine what design variables had an influence on the impact reducing abilities of the helmet design. The helmet was run through a series of Abaqus simulations that determined that a design with two oval shaped channels running along the length of the helmet was best. Next, these options were optimized to generate the helmet that produced the greatest impact reduction. The optimization simulations determined that a helmet that pushed the channels …

An Engineering Approach To Industrial Research And Development Of Pillows, Wesley Patterson
Mahurin Honors College Capstone Experience/Thesis Projects
Comfort during sleep, though taken for granted, involves a great amount of research and engineering. Few give it a second thought, but nearly one-third of a person’s life is spent with their head on a pillow, thus making them a point for increased quality. Having been approached by a tier-1 bedding manufacturer, a team of both mechanical and electrical engineers was been tasked with the goal of creating a valid research tool that the customer, Tempur-Sealy, will utilize in the company’s research and development of high-end pillows. The team sought to tackle this project utilizing tools and knowledge gained throughout …
