Open Access Graduate Research Paper


Three-dimensional printing; Virtual reality in engineering;


This action research investigates the impact of using 3D printing for a Technology Education course in a ninth grade classroom in general, and the effectiveness of students' ability to connect virtual design and manufacturing concepts in particular. There is a current gap in 3D printing research involving the link between designing products virtually using CADD software and the manufacturing processes necessary to create real life products. This action research attempts to fill the current research gap between computer-aided design and product manufacturing for ninth grade students.

Within the three weeks of this experimental design research, as a teacher who teaches Introduction to Manufacturing, I collected both qualitative and quantitative data. I also continually modified the action research project to meet the needs of my students and their instruction. It was found that the use of 3D printers really enhanced student engagement and learning. 3D printers can close students' knowledge gap between virtual design and product manufacturing.
