There were a few things that made ME 270 simultaneously incredibly interesting and difficult. The main factor that challenged me was the variety of topics discussed in class. This design for manufacturability course really pushed me to consider all the different aspects that go into being a successful engineer. Those include careful designing, testing, analytical evaluation, mathematical and statistical analysis, all leading to improved product quality. What I liked the most was exploring all those techniques and how they affect material properties, final product, cost, and quality. I learned so much starting from the different 3D printing methods, to machining, casting, sheet metal, etc. I had no idea about different support materials in 3D printing (and the lack of some). It was also interesting to learn how each affected surface roughness. The machining labs were very interesting. I learned how to think about the specific tool bits and how they affect our design guidelines. Learning about all those different methods to work with metals like forging, casting, sheet metal, forging, really deepened my understanding for design for manufacturing.

From the mini projects I learned to make assumption, to understand heavier reports, summarize information, and work in a group. Perhaps the two most important ones are to make assumptions and work in a group of people. In real life situations, it is impossible to consider all of the underlying factors. However, a successful engineer needs to be able to determine and evaluate the leading factors for the situation. Furthermore, group work, brainstorming ideas, and learning from others is the base of creativity and engineering.

In this course I also learned a lot about myself. My strengths throughout the semester were highlighted during the mini-projects and specifically through the analytical questions. Furthermore, I improved my ability to work in a team despite a busy schedule.

A weakness that I noticed in myself was definitely confidence. Often times I would ask my partners to double-check my work because I was unsure of myself. Also that lack of confidence often made me take longer when doing mini projects. Instead of using critical thinking and analyzing facts to draw conclusions, in the beginning of the semester I tried to find direct answers online. However, by the end of the semester, I learned how to read the main facts and draw conclusions myself. Overall this course was challenging yet very pleasing. The main project made me feel like a real engineer through the well-guided process of initial brainstorming, pds, QFD, cost analysis, and the final CAD, cost analysis and statistical evaluation. I’m glad I’m getting closer to being an engineer.
