Abstract Scope Traditional structural design is a staple of mechanical engineering curricula and typically covered in mechanics of materials. But new additive manufacturing capabilities allow engineers to design structures free of prismatic constraints. Our senior-year machine design lab was modified to include a transition from prismatic to free-form design. Students do an engineering problem designing a 3-point center-pivot lever using dimension, load and weight parameters (Part I). Part II requires the lever to be non-prismatic. Part III, groups redesign their parts to optimize performance. In Part IV, light-weighting is applied through secondary analyses to remove material. Finally, free-form shape optimization is implemented. A metric was developed including progressive assessments of the design process. Results show that students only design with traditional prismatic shapes in Part I. Only half the students combine non-prismatic and efficient cross-sections in Parts II and III. The last Phases show regimented improvement.
