The evolution and widespread presence of advanced computing has created avenues for incorporating more advanced modeling techniques into the classroom at an earlier stage of the engineering educational timeline. Since many students are now already well-versed in using technology in the classroom to enhance technical concepts, it is possible to guide students to more broad and advanced applications of computer aided design. Additionally, with the constant innovation of cheap, accessible rapid prototyping devices, it is now easier than ever to introduce students to manufacturing and prototyping to reinforce concepts and visualize the consequences of their design decisions. However, identifying outdated aspects of the course to be substituted with their modern counterparts can be challenging. In this paper, we describe the decisions made to create a more advanced design environment in an introductory-level course without losing critical engineering design foundations. This includes building a project-based curriculum focused on computer aided design of a product with considerations for multiple manufacturing methods, including 3D printing, laser cutting, and injection molding. In addition to comparing the learning outcomes, we also evaluated the student learning experience to ensure that the changes both increased classroom engagement and student-assessed value of their learning.
