Ph.D. in Mechanical Engineering
In a multidisciplinary Engineering Technology (ET) program with 5 different concentrations, it is not possible to cover the detailed theory and applications of all high-level classes. For this reason, many educational projects are aimed to give students the opportunity to acquire this high-level knowledge through hands-on practice. At the end of these projects, students conclude their experience and prepare a student manual that, later on, guides other groups in getting the same knowledge through hands-on experience. This initiative is applied through some senior design projects as well as through support from agencies such as the Louisiana NASA space grant (LaSPACE). In this paper, an investigation of the effect of 3D printing parameters on the mechanical properties was performed by a senior design student funded by LaSPACE. The scope of the project includes the studying of some printing parameters such as the printing orientation and infill density on the mechanical properties of the commonly used polylactide (PLA), learning experience included following the ASTM standards for tensile and Charpy tests for 3D printed materials, learning how to set up a bench-top vertical testing stand, setup extensometer, and the basics of data acquisition from a load cell and an extensometer using two different software. Along with these learning outcomes, students could analyze the resulting data and compare results to some commercially available data. Besides its undergraduate research component, this project is aimed to expose students to more testing of materials techniques to supplement the knowledge acquired during the course of study in the Engineering Technology program. The acquired experience will be presented with partial results of the project in this work in process.
