Abstract
Allergen Mixing Assistant (AMA) by Xtract Solutions is a device designed to more “effectively refrigerate, organize, and mix allergenic extracts”. Although Xtract Solutions intended the product to be fully automated, the company has decided against its automation and declared its current design as a minimum viable product whose components are too expensive, difficult to source and complex. Therefore, Cal Poly AMA design team - Mitchell Parks and Minwoo Suh - has decided to replace these expensive components with much more economical alternatives as shown below:

Automated Machine Tender, Ryan A. Canfield, Samuel N. Adler, Louis S. Roseguo
Mechanical Engineering
The use of CNC (Computerized Numerical Control) machines automate production in factories through programs controlling manual operations such as milling or lathing. The manufacturing process can be automated beyond the use of CNC machines through the addition of a robotic tender capable of carrying out the same tasks as a human operator. A tender can be integrated into the CNC machine itself, or purchased separately and configured to autonomously operate a particular machine. Smaller companies making limited production runs may not find it economically feasible to purchase large scale integrated machine tenders, but would benefit from a versatile autonomous machine …

Assembly Line Kitting: Foam Mold Material Substitute, Samer Samy Saleh
Industrial and Manufacturing Engineering
Kitting is considered an incredibly innovative and effective solution intended to aid operators within a mixed model assembly line. However, it is a non-value added procedure and one that customers may not be willing to pay for. With this project, the goal is to examine opportunities to employ lean principles and provide a solution that further eliminates non-value added procedures, while also producing the potential for a flexible, mixed model assembly line.
To achieve the aforementioned purpose, the production of foam molds, located within industrial totes and sent to the assembly line, was found to be a major waste within …
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 Effect Of Process Parameters And Surface Condition On Bond Strength Between Additively Manufactured Components And Polymer Substrates, Bharat Bhushan Chivukula
Graduate Theses and Dissertations
Additive patching is a process in which printers with multiple axes deposit molten material onto a pre-defined surface to form a bond. Studying the effect of surface roughness and process parameters selected for printing auxiliary part on the bond helps in improving the strength of the final component. Particularly, the influence of surface roughness, as established by adhesion theory, has not been evaluated in the framework of additive manufacturing (AM). A full factorial design of experiments with five replications was conducted on two levels and three factors, viz., layer thickness, surface roughness, and raster angle to examine the underlying effects …

Microstructure And Properties Of Spark Plasma Sintered Moalb Ceramics, Ting Lou
Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research
Molybdenum aluminum boride (MoAlB) is a ternary transition metal boride which has promising aeronautic and nuclear applications. It inheres excellent properties of the binary transitional metal borides (e.g., MoB, ZrB2) such as high melting temperature, high hardness, and thermal conductivity. Besides, MoAlB is superior to MoB because: (1) the Al element provides an oxidation resistance at high temperatures; (2) its nanolaminated structure consisting of M-B layers with alternating Al layers results in a unique damage tolerance property. In this research, polycrystalline MoAlB have been successfully synthesized and simultaneously sintered using spark plasma sintering (SPS) from molybdenum boride (MoB) …

Cold Gas Dynamic Spray – Characterization Of Polymeric Deposition, Trenton Bush
Masters Theses
When a solid, ductile particle impacts a substrate at sufficient velocity, the resulting heat, pressure, and plastic deformation can produce bonding at the interface. The use of a supersonic gas flow to accelerate such particles is known as Cold Spray deposition. The Cold Spray process has been commercialized for some metallic materials, but further research is required to unlock the exciting material properties possible with polymeric compounds. In this work, a combined computational and experimental study a) simulated and optimized the nozzle flow conditions necessary to produce bonding in a polyethylene particle, b) developed and fabricated an experimental device, and …
