Irina Ciobanescu Husanu, Ph. D. is Assistant Clinical Professor with Drexel University, Engineering Technology program. Her area of expertise is in thermo-fluid sciences with applications in micro-combustion, fuel cells, green fuels and plasma assisted combustion. She has prior industrial experience in aerospace engineering that encompasses both theoretical analysis and experimental investigations such as designing and testing of propulsion systems including design and development of pilot testing facility, mechanical instrumentation, and industrial applications of aircraft engines. Also, in the past 10 years she gained experience in teaching ME and ET courses in both quality control and quality assurance areas as well as in thermal-fluid, energy conversion and mechanical areas from various levels of instruction and addressed to a broad spectrum of students, from freshmen to seniors, from high school graduates to adult learners. She also has extended experience in curriculum development. Dr Husanu developed laboratory activities for Measurement and Instrumentation course as well as for quality control undergraduate and graduate courses in ET Masters program. Also, she introduced the first experiential activity for Applied Mechanics courses. She is coordinator and advisor for capstone projects for Engineering Technology.

Abstract

In recent years there has been a big push to get students into the STEM fields. However, what seems to be lacking in this academic push is the hands on side of it. Engineering simply just isn’t about equations, but actually developing and building a physical product. Something you can touch and in most cases see work. The manufacturing field fits into STEM academics and is very important. With learning the importance of manufacturing, the Senior Design team at XYZ University's ABC Department have decided that one of the best ways to expose new students to exciting Manufacturing Engineering fields from the high school through college level is to give students hands on experiences in this field that would make them interested in it. To do this they have developed a desktop size design of a filament extruding machine for educational use. The purpose of this project was to develop a desktop 3D filament manufacturing device with a production cost under $700 that has been designed to extrude 3D filament spools from recycled thermoplastics. It is designed to fulfill all of the major components of 3D filament manufacture; being material reclamation, filament extrusion, and filament collection on recycled spools. This machine will be tested to extrude the standard 3D printer thermoplastics Polylactic Acid (PLA) and Acrylonitrile Butadiene Styrene (ABS) as well as the thermoplastics Polyethylene Terephthalate (PET), High-Density Polyethylene (HDPE), Low-Density Polyethylene (LDPE), and Polypropylene (PP) that are commonly found in recyclables. The intended audience for this machine are hobbyists as a way form them to reclaim their wasted printing material and for schools beginning at grade four as a classroom demo to demonstrate the properties of thermoplastics, 3D printing, plastic extrusion, and recycling. This machine is designed to reclaim up to 90% of wasted 3D printed material and revert it back to useable 3D filament as well as operate in a safe and controlled condition that is appropriate for school children. The significance of the methodology to be applied in this capstone course project is to combine theory and practice to prepare the students to become better problem solvers and obtain practical solutions to real life/simulated problems using a project based approach. Students in the Mechanical, Electrical, and Industrial fields along with many others can learn many new skills from multi-disciplinary projects such as the design and development of an Injection molding machine for educators. Such projects show students how to use different types of technology, and demonstrate how advanced technology can be used in an innovative application. Overall, many different fields of engineering can benefit from this application, enabling the development of skill and knowledge in many different engineering aspects and processes. This capstone design project stimulates the students’ interest in real-world product realization. As manufacturing laboratories are very expensive to develop, this project can also be adapted at other institutions that have limited funding to improve manufacturing process and prototyping facilities. Expected student learning outcomes assessment in this capstone course was performed using written reports and oral presentations as well as an evaluation of each student’s contribution to the project. Oral presentations were assessed at the end of the first and last quarter and written reports at the end of each quarter. Both written reports and oral presentations were assessed by all faculty members and a number of outside assessors from regional industries. The assessment of individual student contributions was performed by the project advisor and co-advisor. The students’ performance was assessed using a set of performance indicators that are also used to assess the program’s student a-k outcomes (ABET). Each indicator is assessed according to a Likert-type scale and the results weighted to emphasize technical qualities of the work and scaled to produce a score from 0 to 100 in order to determine the students’ final grades.
