Ctrl+P is an online store for 3D printed items, founded by four members with experience in computer-aided design (CAD) and financial management. They initially started with a broader scope but later focused on designing custom pool racks for the pool community. They conducted customer discovery with over 634 ASU students and landed an ongoing business deal with Mill’s Modern Social, a pool hall and bar in Tempe. The team has already made a profit and aims to be revenue-earning by the end of the project. The financial plan includes potential expenses for website development, printer filament, and 3D printers. Ctrl+P's brand mission is to print products desired by customers that consult Ctrl+P. The long-term goal of the team is to continue to gain customers and expand the business to a larger customer base.

As a result of the increase of pollution related to industrialization in Vietnam, acid rain has become a prevalent issue for Vietnamese farmers who are forced to rinse their crops – risking damage due to overwatering and poor harvest. Thus, the team was motivated to develop a solution to harmful impacts of acidic rainwater by creating a system with the ability to capture rainwater and determine its level of acidity in order to optimize the crop watering process, and promote productive crops. By conducting preliminary research on rainfall and tropical climate in Vietnam, existing products on the market, and pH sensors for monitoring and device material, the team was able to design a number of devices to collect, store, and measure the pH of rainwater. After developing a number of initial design requirements based on the needs of the farmers, a final prototype was developed using the best aspects of each initial design. Tests were conducted with varying structural and aqueous materials to represent a broad range of environmental conditions. While the scope of the project was ultimately limited to prototyping purposes, the principles explored throughout this thesis project can successfully be applied to a fully-functioning production model available for commercial use on Vietnamese farms. Given more time for development, improvements would be made in the extent of materials tested, and the configuration of electronics and data acquisition, in order to further optimize the process of determining rainwater acidity.

This study experimentally investigated a selected methodology of mechanical torque testing of 3D printed gears. The motivation for pursuing this topic of research stemmed from a previous experience of one of the team members that propelled inspiration to quantify how different variables associated with 3D printing affect the structural integrity of the resulting piece. With this goal in mind, the team set forward with creating an experimental set-up and the construction of a test rig. However, due to restrictions in time and other unforeseen circumstances, this thesis underwent a change in scope. The new scope focused solely on determining if the selected methodology of mechanical torque testing was valid. Following the securement of parts and construction of a test rig, the team was able to conduct mechanical testing. This testing was done multiple times on an identically printed gear. The data collected showed results similar to a stress-strain curve when the torque was plotted against the angle of twist. In the resulting graph, the point of plastic deformation is clearly visible and the maximum torque the gear could withstand is clearly identifiable. Additionally, across the tests conducted, the results show high similarity in results. From this, it is possible to conclude that if the tests were repeated multiple times the maximum possible torque could be found. From that maximum possible torque, the mechanical strength of the tested gear could be identified.

This thesis paper outlines the Ctrl+P print store business, an honors thesis project conducted through the Founder’s Lab program at Arizona State University. The project is an online store for 3D printed items, operated by a team of four students with backgrounds in engineering and finance. Three team members have experience in computer-aided design (CAD) and can design products to print and sell, while the fourth member is responsible for the financial side of the business. The project began with a broader scope but later focused on the niche community of pool. In the spring semester, the team conducted customer discovery with over 600 ASU students; and in the fall semester, reached out to several pool halls to facilitate feedback on designs of custom pool racks. The team currently has a pending business deal with Mill’s Modern Social, a pool hall and bar in Tempe. The team's goal was to be revenue-earning by the end of the project, and they have already made a profit as a business.

The goal of the presented research is using Electro Field-assisted Nano Ink Writing(EF-NIW) to deposit poly(3,4-ethylenedioxythiophene) polystyrene sulfonate, or PEDOT, on a substrate to serve as a basis for designing high-efficiency, scalable solar cells. Through the analysis of parameters that affect electrospray deposition, methods to accurately produce a PEDOT film will be determined. With the finished, contingent film, tests for efficacy can be performed. The film will be analyzed for profilometry, determining the thickness of the film. The film will then be put up to a conductivity test.
