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 …

3d Printed Aircraft, Matthew Nagy, Charles D'Amico, Alexis Salgado Medina
Mechanical Engineering
This project is to design, build, and test a 3D-printable aircraft. The goal is to create a final design that will be able to fly for the longest duration possible, around 20 seconds. To determine the correct preliminary design and manufacturing process for a 3D printed RC aircraft, an analysis of multiple design options and manufacturing materials was performed. This allowed for a variety of choices for aircraft type, airfoil design, structure, among other topics to be narrowed down to the most promising option. It has been found that the aircraft will follow a design similar to industry motor-gliders, with …
Utilization Of Resin-Based Additive Manufacturing For Investment Casting, Matthew Frost, Isaiah Hong
Utilization Of Resin-Based Additive Manufacturing For Investment Casting, Matthew Frost, Isaiah Hong
Mechanical Engineering
Dr. Xuan Wang, an Industrial & Manufacturing Engineering (IME) professor at California Polytechnic State University, San Luis Obispo, has sponsored the resin-based 3D printing investment cast senior project. The objective of the project was to thoroughly research the process and document the findings of using a resin-based 3D printed part as the pattern for investment casting. While this manufacturing process is not necessarily a new idea, the lack of technical research and documentation limits its ability to be reproducible. The research portion of the senior project included analyzing the limitations to the printing/casting manufacturing process. Measurements of part thicknesses, hole …

Med-Drop Pill Dispenser, Cole Pike, Taylor Morris, Christopher Bruni, Jose Gomez
Mechanical Engineering
Veterans’ Affairs home care nurses currently spend anywhere from thirty minutes to two hours filling out monthly prescriptions one pill at a time to veterans who are unable to leave their homes. The goal of this project was to create an easy-to-use device that could be left at a patient’s home that nurses could use to quickly and accurately dispense medication into the patient’s monthly pill box.
Fiber Length Attrition In Additive Manufacturing, Michael Chapiro
Fiber Length Attrition In Additive Manufacturing, Michael Chapiro
Materials Engineering
Chopped carbon fibers are used as reinforcements in thermoplastics, but the viscous shear forces that arise in melt-processing reduces the fiber length well below its critical length resulting in only moderate strength and stiffness gains compared to the neat resin. This research project aimed to experimentally determine the effect of the melt–flow portion of a single-screw- extrusion process on carbon fiber length attrition in isolation from the immediately preceding screw–plastication step that is responsible for most of the heat needed for melting. Carbon fibers with an initial length of 2 mm were stirred into 5,000 centipoise and 10,000 centipoise silicone …
