ELLIS University of Maine Orono, ME  \nAND  \nJEFF GRAVESON Pratt & Whitney North Berwick, ME  \nABSTRACT  \nGraduating approximately 150,000 engineering and engineering technology students per year, the engineering education system seeks to teach students to solve problems via analysis and design. Unfortunately, many curricula emphasize analysis at the expense of design, often relegating design activities to cornerstone and capstone design courses and leaving students ill-prepared for substantive capstone projects and post-baccalaureate practice. This work seeks to address this problem by introducing an appropriately-scaffolded design-analyze-build-test spine within an existing Mechanical Engineering Technology second-year Strength of Materials course. The 33-student cohort self-selected into 11 teams of 3 students per team to design, analyze, and additively manufacture 6-inch-long by 1-inch-maximum-width by 1-inch-maximum-height 3D-printed polylactic acid (PLA) beams weighing ≤ 45 grams. Beams were then three-point loaded during a culminating competition. The project intentionally rewarded multiple, competing objectives, including beam mass, maximum force at a 0. 050-inch deflection, accuracy of analysis, and creativity. Over 29 calendar days, the project consumed approximately 1.5 in-class hours and was completed using only commonly-available university hardware, e.g., 3D printers and a load frame. Formative and summative surveys were administered to assess student task value, self-efficacy, and opinions. Results indicated that students were primarily motivated by utility and intrinsic task value. Despite 74% of the students having minimal experience with additive manufacturing, 75% of students felt their team had appropriate skills to complete the project. In addition to 84% of students stating the project reinforced their understanding of strength of materials, 95% of students stated that the project increased their understanding of open-ended design and the interconnection between  \n2022: VOLUME 10 ISSUE 3 19  \nADVANCES IN ENGINEERING EDUCATION  \nTeaching Design and Strength of Materials via Additive Manufacturing Project-Based Learning  \nmaterial properties, materials processing, and strength of materials. This work is important in that it demonstrates a case study on how to incorporate design concepts within an engineering analysis course and that analysis and design concepts may coexist within a course.  \nKey words: Rapid prototyping, sophomore, design  \nINTRODUCTION  \nDesign is a fundamental engineering activity in which engineers create new processes and products to satisfy one or more than one performance requirement. Satisfying performance requirements requires three sets of skills: soft skills (e.g., problem definition, communication, teamwork, project management) (Atman et al. 2007; Atman et al. 2008); deductive engineering analyses (Carroll 1997); and inductive reasoning to identify feasible domains and preferred regions within feasible domains (Olson 1997) . The three sets of skills vary in utilization of discipline-specific knowledge and in the uniqueness of solutions. For example, whereas soft skills and inductive reasoning apply to all engineering disciplines, engineering analysis is discipline specific. As another example, although soft skills and inductive reasoning rarely result in unique solutions, engineering analysis seeks to accurately predict a unique solution given a set of assumptions.  \nUndergraduate engineering education often focuses on analytical solutions to well-posed problems, meaning design is a relatively minor component of most engineering programs (Duderstadt 2010) .
