Laser Assisted Manufacturing: A Comparison Of Mechanical Properties Between Lam And Conventional Manufacturing Techniques, William Blakeslee, Neil S. Bailey, Kyung-Min Hong, Shunyu Liu, Yung C. Shin
The Summer Undergraduate Research Fellowship (SURF) Symposium
Laser assisted manufacturing methods, such as direct metal deposition (DMD) and laser beam welding (LBW), are promising methods because of their higher precision and greater productivity when compared to traditional manufacturing methods. Because these methods are relatively new, the mechanical properties of samples produced by laser assisted manufacturing are not well understood. In this study the mechanical properties of samples produced by laser assisted manufacturing methods are analyzed and compared with data obtained from traditional manufacturing methods. The DMD process used Fe-TiC and Ti-TiC metal matrix composites, while LBW used AISI 304 stainless steel. The results vary widely with the …

Applications Of Additive Manufacturing Techniques In Making Energetic Materials, Peter A. Cattani, Trevor J. Fleck, Jeff F. Rhoads, Steven F. Son, I. Emre Gunduz
The Summer Undergraduate Research Fellowship (SURF) Symposium
Energetic materials are currently manufactured using methods such as casting, which can only produce certain geometries. Additive manufacturing enables more flexible fabrication and the potential for improved material consistency. Additive manufacturing has transformed many industries, but has only recently been applied to the manufacturing of energetic materials. This paper describes the development of two processes to apply additive manufacturing methods to energetic materials. Method one applies a fused deposition modelling approach (FDM). 5 µm aluminum powder and PVDF were mixed and made into filaments using a Filabot Original filament extruder. Energetic filaments were created composed of 90:10, 80:20, and 75:25 …

Laser-Assisted Microchanneling On Pmma Substrate Utilizing Two-Pass Fabrication Method, Sijie Zhang, Yung C. Shin
The Summer Undergraduate Research Fellowship (SURF) Symposium
Microchannel is widely used in microfluidic devices for mixing, chemical reaction, detection, particle separation and etc. CO2 laser-based microchanneling of PMMA as a low cost, rapid, noncontact fabrication method has attracted the attention of industry. However, the typical V-shape grooves fabricated by CO2 laser microchanneling have limitations since the V-shape grooves will affect the flow behavior and heat transfer of the fluid, which are important to the performance of microfluidic devices. A two-pass fabrication method is proposed and investigated in this paper to improve the quality of the PMMA microchannel fabricated by CO2 laser. It was found …

Development Of Distributed Off-Grid Renewable Energy System For Rural African Communities, Mateo Sebastian Guerrero, Menghong Feng
Engagement & Service-Learning Summit
Our Hybrid Energy System team is committed to develop low-cost renewable energy solutions to rural African communities where access to electricity from government grid is not available. According to a World Bank’s report, only 24% of sub-Saharan countries have access to electricity. Our team has been working with local partners to build renewable energy systems since 2008. From 2015 the team has been working on micro hydropower turbine and vertical-axis wind turbine with solar energy system combined. Our current efforts include a prototype design of a wind-solar system, using a new concept of vertical axis wind turbine to harvest wind …

The Summer Undergraduate Research Fellowship (SURF) Symposium
There exists a pressing operational need to secure and control access to high-valued electromechanical systems, and in some cases render them inoperable. Developing a reliable method for depositing energetic materials will allow for the near-seamless integration of electromechanical systems and energetic material, and, in turn, provide the pathway for security and selective destruction that is needed. In this work, piezoelectric inkjet printing was used to selectively deposit energetic materials. Nanothermites, comprising of nanoscale aluminum and nanoscale copper oxide suspended in dimethyl-formamide (DMF), were printed onto silicon wafers, which enabled both thermal and thrust measurements of the decomposing energetic material. Various …
Integrating Systems For Liquid/Substrate Characterization And Functional Printing, Jianyi Du, J. William Boley, Rebecca K. Kramer
Integrating Systems For Liquid/Substrate Characterization And Functional Printing, Jianyi Du, J. William Boley, Rebecca K. Kramer
The Summer Undergraduate Research Fellowship (SURF) Symposium
Gallium-Indium alloys are recently applied in fabricating soft devices, such as stretchable sensors, electric circuits, micro pumps and optics. Its printability demonstrates the possibility for a wide extension of the application. Current fabrication methods are inefficient when printing is most handled manually, and are highly dependent on material properties. There is need for a fast way to characterize material properties, and to functionally print the given shape on the substrate. This paper presents the construction of an efficiently integrated system with optical imaging and functional printing for Gallium-Indium alloys. The imaging section allows for characterization of material properties to fast …
Microstructure Development Of Granular System During Compaction, Chen Shang, Marcial Gonzalez
Microstructure Development Of Granular System During Compaction, Chen Shang, Marcial Gonzalez
The Summer Undergraduate Research Fellowship (SURF) Symposium
Granular materials is the second most manipulated material in the industry today. They are easy to transport and more and more newly developed materials cannot stand the process of traditional casting, like energetic materials and bio-materials, but will survive the powder compaction process. Having a better understanding of the microstructure development of granular systems during compaction process, especially for particles that will heavily deform under loading, will give an insight of how to better process the powders to produce materials with overall better performance comparing to bulk materials. The main theory and mechanism applied are Hertz law and nonlocal contact …

Thirty-one percent of annual energy consumption in the United States occurs within the industrial sector, where manufacturing processes account for the largest amount of energy consumption and carbon emissions. For this reason, energy efficiency in manufacturing facilities is increasingly important for reducing operating costs and improving profits. Using microgrids to generate local sustainable power should reduce energy consumption from the main utility grid along with energy costs and carbon emissions. Also, microgrids have the potential to serve as reliable energy generators in international locations where the utility grid is often unstable.
For this research, a manufacturing process that had approximately …

Mechatronics Application To Solar Tracking, Danny L. Rodriguez Jr
Purdue Polytechnic Directed Projects
The purpose of this was to design and implement a two-axis solar tracking system utilizing the National Instruments C-Rio real time controller. In order to accomplish this a prototype was modeled in CAD. This prototype used two 12 V DC motors to change a solar panel's rotation and tilt based on feedback data from three cadmium sulfide photoresistors. This configuration was chosen for its ability to create both a left-right rotational and an up/down tilt differential. In Addition this approach uses National Instruments Labview to control a solar tracking system. Using Labview add uniqueness to this project by adding a …
