Course Description
The second in the Design and Manufacturing Technologies 3D printing and additive manufacturing (AM) curriculum sequence, this course builds upon foundational subject matter knowledge. Course topics include AM workflow and rapid prototyping, emphasizing project-based activities and assignments. Students will learn how to integrate AM into the product development life cycle from prototyping to production while exploring design for AM (DfAM), advanced materials, and state-of-the-art 3D printing and post-processing technologies. To implement assigned projects and activities, students are expected to have working knowledge of at least one parametric modeling CAD software application and produce functional designs.
